Alaska Cruise Weather by Month

The Alaska cruise season generally runs from May to September, with occasional cruises in April and October.

The below chart shows the Alaska cruise temperatures you can expect on the inside passage, along with rainfall and hours of daylight:

Alaska Cruise Weather in May

Highs : 55°F
Lows : 40°F
Average Rainfall : 3.48 inches
Hours of Daylight : 16.5 hours of daylight

Many cruise ships begin their summer deployments to Alaska in May before peak season begins in June.

The Alaska cruise weather in June is fairly cool, but it has the least amount of rainfall during the Alaska cruise season. You can expect Alaska cruise temperatures in May to have lows of around 40 and highs of around 55 degrees Fahrenheit.

May is one of the best times to visit Alaska for dry weather, fewer crowds, and lots of wildlife.

During May, you’ll find several whale species along Alaska’s inside passage. By this time of the year, most of the whales will have completed their migration from the warm waters of Mexico to Alaska, where they will spend the summer.

Spring is also the time to spot newborn wildlife.

You can expect to see lots of snow-capped mountains, and there are fewer insects and mosquitos.

Alaska Cruise Weather in June

Highs : 60°F
Lows : 45°F
Average Rainfall : 3.36 inches
Hours of Daylight : 18.1 hours of daylight

Early June is when the Alaska cruise season kicks into high gear. The warming weather allows cruise ships to travel through the Arctic waters providing unique opportunities for passengers.

The Alaska cruise temperature is warmer in June, with lows of 45 and highs in the low 60 degrees Fahrenheit. Make sure to pack insect repellant when you visit Alaska in June, as mosquitos and other insects can become a nuisance.

The warm weather makes it one of the best times to witness the calving of glaciers.

You can expect 18-20 hours of daylight in June, providing lots of time to enjoy the Alaskan wilderness and abundant wildlife.

June is one of the best months for wildlife sightings, with caribou, black bears, mountain goats, moose calves, and even polar bears out and about.

Alaska Cruise Weather in July

Highs : 65°F
Lows : 50°F
Average Rainfall : 4.14 inches
Hours of Daylight : 17.3 hours of daylight

July is the peak season for Alaska cruises and provides the best Alaska cruise weather and wildlife opportunities. This month has some of the warmest weather, longest daylight hours, and the largest number of tourists.

Temperatures in July average from the high 40s to 65 degrees Fahrenheit.

The warm weather and long hours of sunlight mean you’ll want to pack sunglasses and sunscreen. You should still wear layers when visiting the port, but if you’re planning active shore excursions like hikes or glacier walks, you’ll want to stick with lightweight clothing.

July is an ideal month to visit for salmon fishing, cultural festivals, bear viewing, and small-town exploring. With the popularity of July cruising, cruise prices are at their highest.

Despite having the best weather, Alaska’s weather in July is very unpredictable. You’ll want to pack for all kinds of weather and wear a lightweight rain jacket.

Alaska Cruise Weather in August

Average Rainfall : 5.37 inches
Hours of Daylight : 15.2 hours of daylight

August is when the Alaska cruise season begins to wind down. During this month, you can expect the weather begins to cool, higher rainfall, and gorgeous fall landscapes.

You may be able to find some deals towards mid-August, but expect full fares for the most part.

The chance of rain during this month is over 50%, so you’ll want to pack plenty of waterproof gear – including waterproof shoes and wool socks.

Alaska Cruise Weather in September

Average Rainfall : 7.54 inches
Hours of Daylight : 12.4 hours of daylight

As school returns to session, cruise prices dip and provide travelers with last-minute bargains to take an Alaskan cruise.

The temperatures in September are slightly cooler, with highs of 55 and lows around 40 degrees fair height. September is also the rainiest month of the cruise season. So be prepared to pack lots of rain gear.

September also sees fewer crowds than in the summer. However, the shoulder season has become more prevalent in recent years, making great deals harder to find. Knowing when to book your cruise can help you save money on your trip.

Due to the shorter daylight hours, September provides the best opportunity to see the Aurora Borealis from an Alaskan cruise.

Fun Alaska Weather Facts

Final Thoughts

Alaska cruise weather is unpredictable. The weather conditions can change several times throughout the day, which is why it’s best to pack plenty of layers and a lightweight raincoat.

The best time to cruise Alaska for good weather is between late June and early July. The summer months have the warmest temperatures and the least amount of snowfall.

Not to mention you’ll have a better chance of seeing humpback whales, king salmon, bears, moose, and bald eagles.

The Best Time to Cruise Alaska: A Month-by-Month Guide

Sharing is caring!

Choosing the best time of year for an Alaskan cruise can be challenging. From month to month, the weather, wildlife, and your chances of viewing the mesmerizing Northern Lights vary greatly.

Since I grew up in Alaska, I’m a fan of just about everything in the Land of the Midnight Sun. I also know that your experience can vary widely depending on the month you choose to visit Alaska.

Which raises the question…

When is the Best Time of Year to Cruise to Alaska?

The abbreviated Alaskan cruising season goes from May to September. Although you’ll find the highest number of travelers visiting Alaska during the peak cruising (and fishing) months of July and August, the ideal time for your Alaskan cruise depends most on your personal priorities.

In this post, I share a month-by-month guide about the best time of year for an Alaskan cruise. I’ve included tips on the weather, wildlife, daylight, and the general experience you’ll have each month of the Alaska cruise season to determine when to set sail for the 49th state.

Alaska Cruise Season

The cruising season to Alaska is shorter out of necessity. Weather, ocean conditions, and limited sunlight make winter cruising to Alaska impossible.

For major cruise lines, the Alaska cruise season runs between May and late September, including Viking and Disney.

Many cruise lines also have limited early cruise ships departing for Alaska in April. Norwegian Cruise Lines has the first departures of the season in early April from Seattle.

Holland America Princess, and Royal Caribbean have Alaskan Inside Passage cruises departing from Vancouver at the end of April. Carnival has 14-day Alaskan cruises departing from Seattle and Long Beach in late April.

Alaskan Cruise Month-By-Month Guide

What to Expect on an Alaskan Cruise in April

Spring in Alaska is a unique experience. The benefits of cruising in April include less expensive pricing, fewer tourists, and less crowded ports. Here is a breakdown of other important considerations for an April Alaskan cruise.

Locals typically call the months of April and May “break-up” because the snow and ice begin to break apart and melt after the long winter. What does this mean for tourists? Snow and mud! In April, mountains will still be snowy, and high temperatures will max out in the upper 40s for most cruise ports.

April marks the beginning of the dry season for Southeast Alaska. However, it’s important to remember that this area is part of the world’s largest temperate rainforest.

The average rainfall in Juneau during the month of April is 2.77 inches. Although the rain isn’t convenient, it is the reason for the lush vegetation you enjoy.

Be sure to pack high-quality rain gear for excursions along with warm, layered clothing and a hat and gloves. Many early spring cruisers also pack a winter coat.

Because of its latitude, Alaska experiences extremes in daylight in the summer and darkness in the winter.

On Winter Solstice (December 21 or 22), the state breaks out of its winter hibernation and begins gaining a few minutes of sunlight each day. By the time Summer Solstice occurs (June 20,21, or 22), travelers to Juneau, Alaska, a common port, will experience a day with 19 hours of sunlight.

In April, towns along the Inside Passage will have just over 15 and a half hours of sunlight and will be gaining daylight every day.

Since the skies do still get dark during this month, there is a slight chance that you’ll be able to view the Northern Lights on an Alaskan cruise in April. Peak viewing of the Aurora Borealis happens between November and March, but on a clear night with lots of solar activity, you have a shot at this once-in-a-lifetime viewing experience.

When it comes to Alaskan cruises, balcony cabins come at a premium. You can save money by opting for an inside or an oceanview cabin. However, the views and ability to go sightseeing from your room on ocean days make the higher price worth it.

If you purchase a balcony cabin, you can take advantage of the long days in the Land of the Midnight Sun. As your ship reaches the Inside Passage, the early morning views outside of your room are breathtaking.

There are plenty of animals to see while cruising to Alaska. Arguably, the biggest draw is the marine animals, with opportunities to see pods of humpback whales, gray whales, orcas, sea lions, sea otters, and more.

There are also amazing birds, including bald eagles and land animals like mountain goats, Dall sheep, and brown and black bears.

Although gray whales are more elusive than their humpback cousins, April is your best chance to spot them as they migrate from their winter breeding grounds in Baja, Mexico, to feed in the waters inside the Interior Passage of Alaska.

Orca whales (which are actually members of the dolphin family) are a fairly common site on an Alaskan cruise. “Resident” orcas (who stay near shore and feed on fish) are easy to spot and fun to watch from the cruise ship or on a whale-watching excursion.

General Experience:

Choosing to cruise in the early spring of Alaska will impact your experience. Less travelers might sound appealing, but many port towns aren’t fully “tourist operational” until late June when summer workers start to arrive.

An April sail date is one way to save money on your Alaskan cruise. Just expect cooler weather, fewer wildlife viewing opportunities, and less active ports with some shops that are still shuttered.

What to Expect on an Alaskan Cruise in May

Cruising to Alaska in May is still considered early in the season. As the month progresses, temperatures rise slightly, and daylight hours increase.

While prices in the early season are generally less expensive, your experience during a May cruise will look different from during the high season in July and August. Here is what you’ll find in Alaska in May.

Alaska will still be emerging from winter during May. The high temperature in May in the capital city of Juneau, averages in the mid-50s, with lows in the 40s.

In most Alaska ports, rainfall occurs about 15 days of the month. You’ve got about a 50/50 chance of getting rained or snowed on during excursions. You’ll be very happy if you purchase a quality raincoat and pack clothing you can add or remove in layers.

A hat, gloves, and a winter coat would be a good idea to pack for an Alaskan cruise, especially if you depart in April, May, or September.

Alaska is still gaining sunlight as the Summer Solstice approaches, so you’ll experience longer days during your May cruise.

At the beginning of the month, sunrise in Juneau begins at 5:00 a.m., and sunset is at 8:47, resulting in 15 hours and 47 minutes of daylight. As May closes, the days are even longer, with the sun rising in Juneau at 4:00 a.m. and setting at 9:49 p.m. (almost 18 hours of daylight!).

Another thing to keep in mind when deciding the best month for your Alaskan cruise is wildlife viewing opportunities.

Salmon usually begin their long journeys home to spawn in May, but they come in different waves or “runs.” You might have a chance to view bear feeding on salmon this early in the springtime, but your chances are better later in the summer.

There are exciting marine animals that you can see this early in the Alaskan springtime.

Alaska’s Stellar sea lions are an impressive sight for cruisers. Because they don’t migrate, you have a great chance of viewing these 1000+ pound, 10-foot-long animals on rocks near the shorelines as you cruise. Be sure to listen for their signature roar.

There is also potential for viewing orcas, gray whales, and walruses.

May is an excellent cruising month for birdwatchers as migratory songbirds start to arrive in Alaska and seabirds gather in their nesting spots or rookeries. Keep an eye out for my favorite, the ever-adorable puffins, Arctic terns, cormorants, and bald eagles.

May is a practical choice for Alaskan cruisers who are on a limited budget but want to have slightly warmer and drier weather and more chances to see wildlife. Your views will likely include snowy mountains, but they are gorgeous nonetheless.

Expect less activity and fewer shop openings in some smaller port towns in May since most summer workers are in college and won’t arrive until June.

What to Expect on an Alaskan Cruise in June

Things start hopping in Alaska in June. Summer workers (typically college students) begin to arrive for the peak tourist season, and shops and restaurants open for the summer.

As the temperature warms up, the snow on the ground in port towns melts, and more wildlife begins emerging from their winter dens.

Because school is often still in session for younger children in May and June, taking an Alaskan cruise in the early Spring/Summer is a good choice if you prefer fewer children on board.

In the Lower 48, temperatures in June start to heat up, not so much in Alaska.

While temperatures are warmer and the snow is typically gone at lower elevations, the highs in Juneau average in the low 60s, with lows in the upper 40s.

Temperature is relative, so don’t be shocked if you see an Alaskan sporting shorts and a tank top in June. The 60s can feel downright tropical after winter temperatures in the 20s and 30s.

Rainfall slows down a bit in June, with about 13 days of the month having some precipitation.

Packing-wise, you’ll still want to bring a raincoat, but you can probably leave your winter coat home if you are cruising in June.

It is remarkable to experience Alaska on or around the summer solstice. The amount of daylight increases as you travel northward, but even Juneau’s 19-hour solstice day, with the sun rising at 3:48 a.m. and setting at 10:09 p.m., is a fantastic experience.

If you are in port, you’ll get to see how Alaskans take advantage of the Midnight Sun with locals out biking, hiking, and fishing at all hours of the night.

You’ll also have more hours to look for wildlife from your room window or veranda.

If you have an exterior room and are sensitive to light while sleeping, a sleeping mask will help you rest during these long days.

Humpback whales are the most commonly seen whale in Alaska. They begin migrating from Hawaiian waters in the springtime to feed in the nutrient-rich Alaskan waters.

While it is possible to see humpbacks during the entire cruise season (April-October), your best bet for whale watching will be the months of June, July, and August. They are quite an awe-inspiring sight to see as they travel in pods, breech, and feed.

This is also the time of year when King Salmon runs both begin and end. If you are an angler, there is nothing like hooking and reeling in a King. With an average size of 24 to 36 inches and weighing 10-50 pounds, you’ll finally have a true fishing story worth telling.

If you cruise to Alaska in June, you can expect warmer and drier temperatures, fewer children onboard, increased wildlife sightings, and more cruise offerings.

June is a smart choice for cruisers who don’t want to travel during peak season but want more opportunities.

What to Expect on an Alaskan Cruise in July

Weather is a pretty big consideration when it comes to booking an Alaskan cruise. Temperatures can be quite chilly on deck and in ports of call. If you have a low tolerance for cold weather, cruising Alaska during the warmest months of July and August is a better choice.

July and August are considered peak seasons to cruise to Alaska for good reason. These are the months when all good things combine to create the optimal Alaskan experience.

That being said, the weather and wildlife in Alaska are notoriously unpredictable. You could book a cruise in July and never get above the 50s. You might take a float plane to see bears and, sadly, not see a single one.

My advice is to pack plenty of warm (and waterproof) layers , expect the unexpected, and find joy in whatever experience you get.

The weather in July only trends slightly warmer than June. The average July temperature in Juneau is 64 degrees, with an average low of 51 degrees.

The dry season ends, and precipitation starts to increase in July. Rain falls on average 14 days of the month. Just remember our earlier reminder that you are visiting the world’s largest temperate rainforest and enjoy the lush greenery.

After the Summer Solstice in June, Alaska begins losing daylight with each passing day. While the days are still longer than those in the Lower 48, they are getting slightly shorter throughout July.

In Juneau, the sun rises at 3:54 a.m. at the beginning of July. By the end of July, it starts rising at 4:45 a.m.

Sunsets move to earlier in the night as the month progresses. The sunset on July 1 in Juneau is at 10:07 p.m., and by the end of July, it is at 9:21 p.m.

Although it is getting darker earlier, solar activity is not at its peak in the summer, so your chances of viewing the Northern Lights in July are slim to none.

July is a spectacular month for viewing wildlife in Alaska. Not only are humpback whales, orcas, sea lions, eagles, and seabirds easier to see as they feast in the nutrient-rich summer waters, but the likelihood of seeing the indomitable Alaskan brown, black, and Kodiak bears increase as they focus on fattening up on migrating salmon.

Small-ship Alaska cruise lines like American Queen Voyages and Uncruise can go further into narrow passages and get closer to shoreline wildlife like Dall sheep and bears.

If bear viewing is high on your bucket list and you are traveling on a bigger cruise ship, look for a float plane excursion that will take you to where the bears feed.

July is filled with opportunities to see the stunning wildlife of Alaska while enjoying milder temperatures.

July also brings the highest number of tourists to Alaska. If you cruise to Alaska this month, you can enjoy more shop and restaurant options in port towns but expect things to be slightly more crowded.

What to Expect on an Alaskan Cruise in August

August is a delightful time to cruise to Alaska. You’ll enjoy wildlife viewing, warmer temperatures, and daylight returns to more typical hours. However, the dry season has ended, so rainfall will begin to increase as the month progresses.

For cruise itineraries in Alaska, August high temperatures will be somewhere in the upper 50s and low 60s. We’ve reached the pinnacle of summer temperatures, and the rainier season has just begun.

Juneau gets about 17 days of rain in August, so a high-quality raincoat is essential.

With lows in the 50s, you don’t need to pack a winter coat and hat, but be sure to include warm, wicking layers to keep your temperature steady.

By the end of August, the sunrise and sunset times in Alaska are pretty close to “normal” times for most states in the USA. You might feel like you aren’t getting the true Alaskan “Midnight Sun” experience this month.

In Juneau, on August 31, the sunrise is at 5:52 a.m., and the sunset is at 8:01 p.m.

The loss of daylight does mean you could see the Aurora Borealis while cruising to Alaska in late August. The best time to see the Northern Lights is between late August and April, typically peaking in March.

Unfortunately, seeing this supernal show of sun activity is not a given. Overcast skies are common in Alaska and block the Lights, and the solar activity that creates the phenomenon is unpredictable. You can increase your chance of seeing the Northern Lights by asking crew members if you can get placed on a list that will be notified when, as we say in Alaska, “the lights are out.”

In August, the wildlife can sense that winter is on its way, and activity picks up to prepare for the months of cold, snow, and darkness.

You might see bears that are continuing to fatten up before hibernation. Humpback whales have yet to begin their migration to warmer waters, so you will still be able to see them, especially in early August.

Seabirds will still be feasting on fish. You also might see fuzzy harbor seal pups and sea lion pups (born in June and July) warming themselves on rocks with their mothers. Add high-powered binoculars to your Alaska packing list to ensure that you get to see all of the wildlife possible.

General Experience :

You can’t go wrong with a cruise to Alaska in August. Not only is it your best shot for warmer weather, but you’re also sure to see a good amount of the wildlife Alaska is famous for.

Warmer weather in Alaska also has an unexpected bonus for cruisers in the form of glacial calving.

Glaciers are a natural wonder that no photographs can do justice. Until you have experienced the majesty of an ancient river of ice in an unparalleled blue, it is hard to imagine!

Every Alaskan cruise includes at least one glacier viewing stop. The warmer the weather, the better your chance to view a once-in-a-lifetime occurrence called “calving.” This is when a large chunk of the glacier separates in a giant icy landslide.

Not only is the cracking sound shocking, but the calving also produces a giant wave of water and captivating icebergs. July and August are prime time for viewing glacier calving on an Alaskan cruise.

What to Expect on an Alaskan Cruise in September

April, May, and September are considered shoulder seasons for cruising to Alaska. Shoulder season is the time between peak season and off-season when there are fewer cruisers and lower prices.

A September cruise has its benefits, including less crowding and cheaper prices. However, a cruise this time of year will also slightly decrease your chance of viewing wildlife and make for sleepier ports of call because most summer workers return home for college.

In Alaska, we measure the return to winter by how far up the stalk Fireweed flowers have bloomed. By September, the blooms are most certainly to the top as winter rapidly approaches.

High temperatures in September in Juneau hover around the upper 50s with lows in the mid-40s, though, so it is still an enjoyable time to visit.

Precipitation increases to 19 days of the month, so pack a raincoat with a hood (you’ll be grateful to have it!).

There is a chance you will see some snow, so a winter coat, gloves, and a hat are a smart addition to your packing list.

In September, the scale now tips towards later sunrises and earlier sunsets in Alaska. By the end of September, there are less than 12 hours of daylight in Juneau.

Cruising in September will give you the highest chance of viewing the Aurora Borealis on an Alaskan cruise. You won’t want to miss this indescribable sight, so watch for clear night skies and set an alarm to go on deck (or on your balcony) for potential middle-of-the-night Northern Lights shows.

Gray whales and Humpback whales begin their migration to warmer waters in October and November, so you still have a chance to see them in Alaskan waters in September.

Birds also haven’t started their migration, so you can spot both songbirds and seabirds as you cruise along the coast.

Silver salmon runs are possible in September, but not a guarantee.

September is also an excellent time to witness a towering Alaskan moose. By this time of year, bull moose have a full rack of antlers. With shoulder heights at 6 foot 9 inches and over 1,400 pounds, these massive animals are as dangerous as impressive, so you’ll want to view them from a distance.

Cruising to Alaska in September has many benefits of the peak season (milder weather and good wildlife viewing) with less expensive prices and fewer tourists.

Although the weather will likely include more rain, you have a better chance of viewing the Northern Lights, which might outweigh this drawback.

If your itinerary includes stops in Anchorage, Seward, or Whittier, you might experience rougher seas as you cross the Gulf of Alaska in September.

FAQs About Alaskan Cruises

What is the best time of year to see the northern lights on an alaska cruise.

The peak season to view the Northern Lights or Aurora Borealis is between late August and late April, which unfortunately doesn’t overlap much with the Alaskan cruise season. If the Northern Lights experience is high on your Alaska bucket list, consider a September cruise with more dark nighttime hours and increased solar activity.

How far in advance should you book an Alaskan cruise?

If you are hoping to travel during peak Alaskan cruise season (July and August), you should plan on booking your Alaskan cruise at least one year in advance. The farther in advance you can book your Alaskan cruise, the more options you will have for cruise dates, itineraries, and cabin amenities.

Are the seas rough on an Alaskan cruise?

When traveling from Vancouver in the Inside Passage of Southeast Alaska, the waters are mostly protected and provide smooth sailing. If ports include Anchorage, Seward, or Whittier, cruise ships must cross the Gulf of Alaska, which has notoriously rougher waters. This is especially true after Labor Day.

Alaska Cruise Weather in May

May brings warmer weather within the cities and towns of the Alaskan inside passage. While it can be freezing cold at times, the weather can also be pleasantly cool. The low temperatures typically range from the mid-thirties to the low forties Fahrenheit, but the highs can get up to the upper fifties.

This month also experiences near constant cloud cover with a good chance of rain on any given day. Travelers get at least fifteen hours of daylight and twilight in May, providing more time for whale watching and other outdoor activities. With low wind speeds, cold temperatures, and precipitation, travelers may want to pack plenty of knit sweaters, a jacket, warm pants, and waterproof boots or shoes.

Alaska Cruise Weather in June

Most of the month of June in Alaska is either cold or pleasantly cool with very cold temperatures being less frequent than in May. The lows can be as low as forty-three degrees Fahrenheit, and the highs can get up to the sixties on average.

Cloud cover and precipitation conditions from May persist throughout June and July, and wind speeds remain low as well. Layers are essential for this type of fluctuating weather, and travelers should be sure to pack waterproof jackets and shoes for rainy moments, cardigans or light sweaters, and other warm clothes like jeans, long skirts, and tights.

Alaska Cruise Weather in July

July is known as the hottest month in this section of Alaska with the hottest day of the year falling on July 9th. Temperatures range on average between fifty and sixty degrees with mostly cool afternoons and evenings and chilly mornings and mid-day hours.

The late nights and early mornings can be very cold, but these are also the hours when most people are asleep in their cabins. Travelers cruising to Alaska in July should be sure to pack plenty of layers along with some waterproof outerwear, but they should pack light, removable layers to adjust to the warmer temperatures of the afternoons.

See Mendenhall Glacier on a Cruise to Alaska

Alaska Cruise Weather in August

August brings a gradual decrease in temperatures again, but it is still one of the hottest months of the year in this region. Temperatures during this month usually range from the mid-forties to the low sixties, and days are typically cool or chilly.

Like July, nights and early mornings can be very cold, so late nighters and early risers should be prepared to bundle up for icy temperatures. Plenty of layers are also essential in August, and travelers should be sure to pack waterproof jackets, shoes, and bags as August and September are among the rainiest months of the year.

Alaska Cruise Weather in September

September is one of the last months of the cruise season in Alaska and it is also one of the coldest, with temperatures staying in the low to high forties on average. As the month advances, the temperatures drop lower and lower, and the nights and early mornings can be bitterly cold.

The abundant cloud cover and frequent rain make the landscape all the more beautiful, but visitors should dress properly for a better overall experience. Travelers still get at least twelve hours of sunlight for excursions and deck activities, but they should pack thick pants, knit sweaters, and insulated shoes to combat the cold along with waterproof rain gear.

Alaska Cruise Weather in October

October in Alaska can see lows can be as low as 28° Fahrenheit, and the highs can reach up to 40° Fahrenheit. You can also expect more precipitation, which can result in some snowy weather.

Both September and October are ideal times to see the stunning Northern Lights, otherwise known as aurora borealis displays. The best times to look is between Midnight and 2am.

While Alaska might be colder than other summer vacation spots, it offers unique experiences that can’t be found anywhere else. These include sightings of wild orcas , sea lions, and humpback whales and riding one of the world’s longest ziplines.

You’ll also have a chance to visit the incredible Butchart Gardens, witness glaciers, pan for gold , hike through temperate rainforests, and much more. If you’re prepared for the weather and pack the right attire for your destination, nothing can get in the way of having a good time.

Cruising Alaska in Late September

2016, second week of September. It snowed in the Yukon and followed us down the mountains back into Skagway. We about froze in Glacier Bay. I wore three pairs of everything that day, couldn't fit in a booth at lunch without taking several layers off. I loved every minute of it.!

Alaska is always a crapshoot weather-wise. I went one time in mid-September and sunny Anchorage reached 80 degrees.

Our first cruise in 2018 was to Alaska in mid-September. It was overcast, rainy, and cold the whole trip.

We could not use our balcony because of the rain/cold. The good part was it was not crowded.

In spite of the weather, it was our most memorable cruise. We slowly cruised through a pod of 30+ whales who were feeding on a school of fish. If you go, be prepared for poor weather and hope for sunshine.

JMO, but the best part of visiting Alaska in September is that THE SALMON ARE RUNNING!!! Out at the Mendenhall Visitors Center they have a platform over Steep Creek where you can watch the bears fishing. In Sitka, if you walk through the beautiful forest (Sitka National Historical Park) there are bridges over the Indian River where you can also see them running and spawning.

I think you just have to be prepared. We cruised in September 2018 and had good weather the whole trip. We're cruising to Alaska again this September. Pack layers. Sailing near the Margarie Glacier was our coldest moment of our previous cruise.

We have sailed to Alaska in early June and late September. We were lucky to have reasonable weather both times, apart from heavy rain in Juneau in June. We actually preferred the early June sailing as there was still snow around, particularly on the White Pass train trip. Also the approaches to Glacier Bay, as I remember were all snow covered in June. On the September trip I did not think the scenery was as atmospheric, and somehow not as beautiful. Although Glacier Bay at any time of the year is just amazing. One advantage of going in late September is there are a lot of bargains to be had in the shops. We bought some beautiful local greeting cards in Juneau and Ketchikan.

Having said all this however, I would happily jump at the chance to go back to Alaska at any time of the year!

Thanks to everyone who has replied. I just booked Nieuw Amsterdam form Sept. 25-Oct. 2. Last HAL cruise to Alaska for the season, I believe. Unfortunately, I can't stay on to go to FLL... ☹️

You'll have a great time @DCThunder .

We have taken three September AK cruises. The last one was a 14-day roundtripper that departed from Los Angeles on September 19, 2019.

I would say that for the most part we encountered cool weather. The only days that were really cold were sea days, and, even then, I was not uncomfortable taking my daily walk on the promenade deck wearing a jacket that I bought at Costco for about $40. Weather at most of the port stops was pretty mild, although, drizzle is not uncommon. Incredibly, on one visit to Ketchikan, in the middle of a rain forest, it was sunny and quite warm--in the 80s.

As many have stated, however, past performance does not necessarily forecast the future. Count on encountering some rain and, possibly, fog. Typically, the rain is no big deal. As I indicated, our experience has been drizzle in the ports. Nothing that prevented us from enjoying ourselves. The only time we encountered a big storm on an AK cruise was while crossing the Gulf of Alaska on a southbound itinerary. It was awesome. It was also in August.

As another poster has indicated, many of the stores at the ports are trying to clear out inventory. So, if you need to buy a fleece, you may stumble into a good deal, I walked off the ship in Skagway without a hat to keep my baldy head warm. I really did not want to board the ship and walk to our cabin to retrieve my hat, In the first touristy souvenir type store, I found a baseball cap for $2.

Hey there @DCThunder ! I'll be on board with you. This was actually not a planned trip but I'm going on the Vancouver to FLL cruise and the cabin I'm booked in "just happened" to be available for Alaska, so, why not??? It does present a bit of packing challenge to go from Glacier Bay to Panama to Florida, but layering will be the solution! I see you just posted on the roll call so I hope maybe the small contingent of CCers can meet up somewhere at the beginning to say hi.

Weather in Alaska is so random that I will just prepare for anything. The only real disadvantage for me is that by the end of September the sun sets so much earlier than June/July. Sunset times in Skagway to Ketchikan will be around 6:30pm - 6:45pm the week we will be there.

One notable thing about late September. You have a chance (def not guaranteed) to see the Northern Lights. You have practically zero chance in June-August.

Yay , and welcome aboard to the cold leg of our Fire and Ice cruise on the NA in Fall of 2022 and thank you for linking the two of them together . Only 2 months to go . 🦥 🐧

BTW: September is great for Glacier Bay! Ships get permission to go past Jaw Point at Johns Hopkins Glacier and you get a much better viewing of the glacier and seals on the ice flows.

Good to know. We did a Seattle RT (including Glacier Bay) at the end of May, and I thought it was a great time (the greenery at low elevation with the snow still on the mountains), but I was thinking about going back and doing a one-way southbound in September in a few years to see the interior and Hubbard Glacier.

May was a fantastic time this year, with snow right down to the ocean in places! Most snow for many years apparently. Glad you saw some greenery, the best of both.

That would be the cherry on top if the Northern Lights made an appearance! I'll google to check on the NL probability during that time.

Thanks for mentioning that @vicd1969 !

May I suggest 32degrees.com for both short/no sleeved and LS shirts. I have just ordered the remaining 3 colors of WOMEN'S AIR MESH LONG SLEEVE T-SHIRT. In the heat they are wicking and breathable and I believe in the chill they will be a fine undershirt even though they are sold as 32^COOL (not 32^HEAT). There are other companies like this (Arctic Cool is one) but 32degrees.com seems to be in permanent clearance mode!

Hey thanks @crystalspin ! I will check into them tomorrow. I can use all the help I can get when it comes to clothes.......I'm very wardrobe challenged! 😏

Alaska Weather in September: The Ultimate Guide

Posted on Last updated: March 4, 2024

Dive into the heart of Alaska weather in September with our ultimate guide.

Discover how the transition from summer to fall influences weather patterns, activities, and the breathtaking landscapes, ensuring your Alaskan adventure is nothing short of spectacular.

General Weather Conditions in September

September in Alaska, a time of significant transition, beckons with the allure of crisp autumn air, the last whispers of summer warmth, and the early hints of winter’s chill.

This month marks a pivotal shift in the Alaskan climate, offering a unique blend of weather conditions that vary significantly across the state’s vast landscapes.

From the lush rainforests of the Southeast to the rugged interiors and the icy northern frontiers, September weaves a complex tapestry of climatic patterns.

Here, we delve into the general weather conditions you can expect during this enchanting month, ensuring you’re well-prepared for your Alaskan adventure.

Average Temperatures and Weather Patterns

Average Temperatures

September sees a wide range of temperatures across Alaska.

The southern coastal regions, frequented by Alaska cruises and influenced by the milder maritime climate, typically enjoy daytime highs in the mid-50s to low 60s (°F), while evenings can cool down to the 40s.

In contrast, the interior regions experience a broader temperature swing, with daytime highs comfortably in the 50s but dropping to the low 30s or even colder at night.

The Arctic regions present a more stark transition to colder weather, with temperatures often dipping below freezing, heralding the early onset of winter.

Weather Patterns

The weather in September can be as unpredictable as it is varied. The early part of the month may still hold onto the summer’s tail, with warmer days and relatively stable weather.

However, as the month progresses, the likelihood of rain increases, particularly along the coastal areas where the lush rainforests of Southeast Alaska can receive significant rainfall.

This moisture-laden air can lead to foggy mornings, especially in coastal valleys and inlets, adding a mystical quality to the landscape.

The interior and northern parts of the state, shielded from the Gulf of Alaska ’s moisture by mountain ranges, see less precipitation but can experience the first snowfall of the season by late September.

These areas are also subject to more pronounced temperature drops at night, a reminder of the winter that lies ahead.

Daylight Hours

One of the most noticeable changes in September is the reduction in daylight hours. Alaska is famous for its extreme day length variations, and September does not disappoint.

While the month begins with the remnants of summer’s extended daylight, the nights quickly begin to reclaim their dominance.

This gradual decrease in daylight not only affects the temperature but also plays a significant role in outdoor planning and activities.

In the northern reaches, this transition is more pronounced, offering the first glimpses of the Aurora Borealis as the nights grow longer and darker.

Regional Weather Breakdown

Interior Alaska : The heartland of Alaska experiences a dry, continental climate, with clear, crisp days becoming more common as the month advances. The chance of frost increases, particularly in low-lying areas, making for some spectacular early morning scenery.
Coastal Alaska : The coasts, particularly the Southeast (the Panhandle), are known for their wetter climate. September continues this trend, with higher precipitation levels than the interior regions. However, the storms can also bring dramatic skies and a fresh, clean air that enhances the natural beauty of the coastal landscapes.
Northern Alaska : The Arctic regions enter a pre-winter phase, with temperatures often dropping below freezing. This area sees a dramatic decrease in daylight, setting the stage for the Northern Lights , which begin to make their magical appearances on clear, dark nights.
Southern Alaska : This region, encompassing the Kenai Peninsula and the Anchorage area, tends to have a mix of rain and sun. Early September can still offer days warm enough for outdoor adventures, but the weather becomes more unpredictable as the month progresses, with an increased chance of rain showers and cooler temperatures.

Understanding the general weather conditions in September is crucial for anyone planning a visit to Alaska during this time.

The month’s variability, influenced by geography and seasonal transitions, offers a unique experience that can be profoundly different depending on where you are in the state.

Armed with this knowledge, travelers can better prepare for their Alaskan journey, ensuring they embrace the natural beauty and diversity of the state with the right expectations and preparations.

Alaska’s vast expanse encompasses a wide range of climates and ecosystems, leading to diverse weather patterns across its regions in September.

Here’s what travelers can expect in different parts of the state during this transitional month.

Interior Alaska

Temperature Ranges and Anomalies : The Interior experiences some of the most significant temperature swings in Alaska, with daytime highs comfortably in the 50s (°F) early in the month, dropping to the 30s and lower by month’s end. Nights can be chilly, with temperatures often dipping below freezing as September progresses.
Precipitation Levels and Weather Events : Rainfall is relatively low, but snow can start appearing towards the end of the month, especially in higher elevations. The weather is generally stable, with clear skies offering excellent conditions for viewing the Northern Lights.
Recommended Clothing and Gear : Pack layers, including thermal undergarments, fleece or wool mid-layers, and a waterproof, insulated outer layer. Don’t forget warm socks, a hat, gloves, and sunglasses for the bright, sunny days.

Coastal Alaska

Temperature Ranges and Anomalies : Coastal regions, especially in the Southeast (e.g., Juneau and Ketchikan ), maintain milder temperatures ranging from the mid-40s to low 60s (°F). The weather is more humid here, with a higher chance of rain.
Precipitation Levels and Weather Events : September can be quite wet, with steady rain increasing throughout the month. This precipitation supports the lush, green landscapes but can lead to soggy conditions for outdoor activities.
Impact of Weather on Wildlife Viewing and Fishing Activities : The rain doesn’t deter the wildlife. Bears, eagles, and other animals are active, taking advantage of the salmon runs. Fishing can be excellent, though weather conditions may affect charter schedules.

Northern Alaska

Temperature Ranges and Anomalies : This region sees the earliest signs of winter, with temperatures ranging from below freezing to the low 40s (°F). Snow is likely, especially in late September.
Precipitation Levels and Weather Events : Snowfall rather than rain characterizes the month’s precipitation, with the potential for winter storms as the month progresses.
Visibility Conditions for Northern Lights : Clear, cold nights provide some of the best opportunities to view the aurora borealis, with activity typically increasing towards the end of the month.

Southern Alaska

Temperature Ranges and Anomalies : Southern Alaska, including the Anchorage area, experiences temperatures similar to the coastal regions but with slightly less precipitation. Expect temperatures to range from the low 40s to mid-50s (°F).
Precipitation Levels and Weather Events : Rain is common but not as persistent as in the Southeast, with occasional clear, crisp days. Early snow can appear in higher elevations.
Effects on Local Tourism and Outdoor Activities : The milder weather supports a range of activities, from hiking in Chugach State Park to sightseeing in Anchorage. Tourist numbers dwindle, making it a great time to enjoy the region without the crowds.

September’s weather in Alaska is as varied as its landscape, with each region offering unique experiences and challenges.

Travelers should prepare for a wide range of conditions, from rainforests’ dampness in the Southeast to the frigid nights of the North.

Understanding these regional characteristics allows for better planning and a more enjoyable Alaskan adventure.

What to Pack for Alaska in September

Packing for a September trip to Alaska requires thoughtful preparation due to the diverse and changeable weather conditions.

Here’s a comprehensive guide to ensure you have everything you need for a comfortable and enjoyable visit.

Essential Clothing

Must-Have Items for Unpredictable Weather Changes

Umbrella : Useful for light rain, especially in coastal towns.
Insect Repellent : Depending on the year, September can still have active mosquitoes, especially in wooded areas.
First Aid Kit : Always a must-have, including blister care for new or wet hiking boots.
Personal Medications and Toiletries : Including lip balm and moisturizer to combat dry, cold air.
Layers for All Conditions : Even if the forecast looks clear, conditions can change rapidly, making it essential to have layers for cold, rain, and wind.

The unpredictable nature of Alaska’s weather in September necessitates a well-thought-out packing list.

By preparing for everything from cool, crisp mornings to rainy afternoons, you’ll be able to fully enjoy the stunning beauty and adventure that Alaska offers during this transitional season.

This guide ensures you’re well-equipped for the vast range of activities and weather conditions you may encounter.

Activities Suitable for September Weather

Whether you’re drawn to the great outdoors or prefer the comfort of indoor exploration, there’s no shortage of things to do that cater to the season’s conditions.

Outdoor Adventures

Pro Tip : For a truly breathtaking experience, hike the trails around Exit Glacier, where you can witness the stark beauty of Alaska’s changing landscape.
Pro Tip : Check local regulations and consider hiring a guide for the best fishing spots and techniques.
Pro Tip : Visit wildlife conservation centers or national parks with guided tours to safely observe animals in their natural habitats.

Indoor Activities

Museums and Cultural Centers : For those rainy days, Alaska’s museums and cultural centers offer insights into the state’s rich history and diverse cultures. The Anchorage Museum and the Alaska Native Heritage Center are must-visits, featuring art, historical artifacts, and interactive exhibits.
Pro Tip : Don’t miss the chance to try some of Alaska’s craft beers or locally distilled spirits, which often incorporate unique Alaskan ingredients.

Whether you’re capturing the fall colors on a backcountry hike or savoring the local cuisine, September in Alaska offers an unforgettable experience with a little bit of everything for everyone.

Tips for Traveling in Alaska in September

Traveling to Alaska in September can be an enriching experience, offering unique sights and adventures amidst the transitioning seasons.

However, being prepared and knowing what to expect can make a significant difference in how enjoyable and smooth your trip will be.

Here are some essential tips for navigating Alaska in September:

Stay Informed About the Weather

Check Forecasts Regularly : Alaska’s weather can change rapidly, especially in September. Use reliable weather apps or websites, and check local forecasts frequently to stay ahead of any significant weather changes.
Understand Regional Variances : Remember that weather can be drastically different between regions. What applies to the coast may not hold true for the interior or northern parts.

Safety Tips for Outdoor Adventures

Prepare for the Outdoors : If you’re planning hikes or any outdoor activities, ensure you have the right gear, including bear spray in bear country, maps, and a compass or GPS device. Familiarize yourself with local wildlife safety tips.
Let Someone Know Your Plans : Always inform someone—a hotel concierge, a friend, or park rangers—of your travel plans, especially if venturing into remote areas. Cell service can be spotty in many parts of Alaska.
Be Bear Aware : September is a time when bears are actively preparing for winter, which means they can be more visible as they search for food. Keep a safe distance, store food appropriately, and know what to do if you encounter a bear.

Making the Most of Daylight Hours

Plan Activities According to Light : With daylight hours decreasing over the month, plan your activities to make the most of the light. This might mean starting your day earlier or being strategic about visiting certain sights when they’re best lit.
Northern Lights Viewing : For those hoping to catch the aurora borealis, the increasing darkness in late September improves chances. Check aurora forecasts and plan to be in areas with little to no light pollution for the best viewing experiences.

Navigating Transportation

Book in Advance : While September isn’t peak tourist season, it’s still a good idea to book flights, car rentals, and accommodations in advance, especially if you’re planning to visit popular destinations or attend specific events.
Be Prepared for Driving Conditions : If you’re renting a car, ensure it’s equipped for potentially slippery conditions. Ask about including chains or opting for a vehicle with four-wheel drive if heading into higher elevations or more remote areas.

Embrace Local Experiences

Attend Local Events and Festivals : September hosts various local events celebrating the end of summer and the beginning of fall. These can provide deep insights into local cultures and traditions.
Try Seasonal Foods : Many local eateries will have seasonal specialties featuring freshly harvested ingredients and seafood. It’s a great time to enjoy the local cuisine.

Health and Comfort

Stay Hydrated and Moisturized : The cooler, drier air can affect hydration and skin health. Drink plenty of water and use moisturizer to combat the dry air, especially in heated indoor environments.
Pack for Comfort : Include a good mix of warm and waterproof clothing to adapt to Alaska’s unpredictable September weather. Comfortable, waterproof footwear is essential for exploring the outdoors.

By following these tips, travelers can fully enjoy the natural beauty and unique opportunities Alaska offers in September, ensuring a memorable and safe experience.

FAQs on Alaska Weather in September

Can i see the northern lights in alaska in september.

Yes, September is a great month to see the Northern Lights in Alaska, especially towards the end of the month as the nights get longer and darker. The best viewing locations are away from city lights, in places like Fairbanks or the Denali National Park area.

Is September a good time to visit Alaska for wildlife viewing?

September is an excellent time for wildlife viewing. Bears are preparing for hibernation and are more active in searching for food. Moose are in their mating season, and migratory birds are beginning their journey south. Always observe wildlife from a safe distance.

What are the chances of encountering snow in Alaska in September?

Snow chances increase as you move towards the end of September, particularly in higher elevations and more northern areas. While it’s less common in coastal and southern regions, travelers should be prepared for possible early snowfalls in these areas as well.

Are there many tourists in Alaska in September?

September is considered shoulder season in Alaska. While there are fewer tourists compared to the peak summer months, popular destinations can still be quite lively, especially early in the month. By late September, you’ll experience lower crowds, making it a great time to visit for those seeking a more secluded experience.

How should I dress for the weather in Alaska in September?

Layering is key. Start with a moisture-wicking base layer, add an insulating layer (like fleece or wool), and top with a waterproof and windproof outer layer. Don’t forget accessories like gloves, a warm hat, and waterproof boots.

Are day trips and excursions still available in September?

Yes, many tour operators continue to offer day trips and excursions throughout September, including boat tours, fishing trips, and wildlife viewing excursions. However, some services may start to reduce their availability towards the end of the month, so it’s best to check in advance.

What kind of driving conditions should I expect?

Road conditions in September are generally good, but you should be prepared for anything. Early snowfall can occur, especially in northern and interior regions. Always check the weather forecast and road conditions before heading out, and consider a vehicle with four-wheel drive if you’re exploring more remote areas.

Is it necessary to book accommodations and activities in advance?

While September isn’t as busy as the summer months, booking your accommodations and activities in advance is still a good idea, especially for popular destinations or specific experiences like Northern Lights tours or fishing charters.

How can I stay safe while hiking or exploring remote areas?

Always let someone know your plans, carry a map and compass (or GPS), bring sufficient food and water, and dress appropriately for the weather. Be bear aware, carrying bear spray and knowing how to store food properly if camping.

Can I fish in Alaska in September?

September is a fantastic month for fishing in Alaska, with opportunities for both freshwater and saltwater fishing. Salmon runs are still active in many areas, and trout, halibut, and other species are also plentiful. Be sure to check local regulations and obtain the necessary fishing licenses.

Alaska Cruise Weather

What to expect and when to visit

Cruise season in Alaska is just five months long, running from May to September, although Holland America Line offers Alaska cruises in late April and early October.

So when is the best weather to cruise Alaska? Keep in mind that Alaska and the Yukon make up an enormous mass of land; in fact, combined they are about half the size of the lower 48 states! As you can imagine, it can be difficult to speak in generalities about the climate for a place so vast. However, we’ve broken down the weather in Alaska by season and area, with advice on what to expect, so you can choose the best time to cruise to Alaska.

Weather In Alaska By Season

Temperatures will be lower in the spring (early May to late June), and the weather a bit more unpredictable, but on the plus side there are fewer visitors in Alaska and the prices are likely to be a bit lower. So if you’re on the hunt for some of that famous northern solitude, spring is the time for you. And best of all, the land is bursting back to life after the long, cold winter months. Flowers are blooming, bears are rousing from their slumber, and a sense of renewal permeates the land. So, don’t scratch spring off your calendar just because Alaska’s climate may not be ideal.

Average Spring Temperatures:

Inside Passage/Southeast; Southcentral; and Interior: daytime highs in the mid 50s to upper 60s, with low temperatures in the mid to upper 30s.
Far North/Arctic: daytime highs in the mid 20s to upper 30s, with low temperatures in the mid-teens to upper 20s.

Summer is the peak season for tourism and considered the best time for Alaska cruises, and for good reason. Running from late June to mid-August, summer has the warmest temperatures, near endless sunlight (approximately 18 hours or more per day!), and the best chances for viewing wildlife . And with the tourism industry in full swing, you’ll find more services and a seemingly endless list of activities to take part in. But you won’t be alone — more stuff to do and nicer weather in Alaska means more people — and the prices will generally be a bit higher.

Average Summer Temperatures:

Inside Passage/Southeast; Southcentral; and Interior: daytime highs in the low 60s to low 70s, with low temperatures in the upper 40s and low 50s.
Far North/Arctic: daytime highs in the low to mid 40s, with low temperatures in the lower 30s.

Denali National Park in Alaska at Autumn

This is when Alaska and the Yukon are enjoying a last hurrah before winter sets in. Running from late August through September, fall in Alaska can feel very much like spring. The temperatures will be cooler and the weather more unpredictable, but, like the spring, prices will often be lower and you’ll have less company. And the Alaska wildlife viewing can rival that of the summer, as creatures great and small are out prepping for the barren, frigid months ahead. With fall comes shorter days, but this isn’t without its advantages. Shorter days mean there is an excellent chance of seeing the Northern Lights (Aurora Borealis) in the late evenings.

Average Fall Temperatures:

Inside Passage/Southeast; Southcentral; and Interior: daytime highs in the mid 50s to low 60s, with low temperatures in the low 40s.
Far North/Arctic: daytime highs in the mid to upper 30s, with low temperatures in the mid 20s.

Each season has its pluses and minuses and the best time to cruise to Alaska depends on what’s important to you. Now that you know what to expect from the weather, peruse Alaska cruise itineraries .

P.S. September is the beginning of winter type weather for many Alaska places.

Also, the “glacier” options are:

Inside Passage and Endicott

Icy Strait Point and Endicott Arm

Glacier Bay National Park and Icy Strait Point (Hoonah)

Stephens Passage, Glacier Bay National Park and Icy Strait Point (Hoonah)

Glacier Bay National Park

There have been some past Septembers where the weather was such that some ships could not dock at some ports which they had to skip/

All the cruises you are looking at head out into open ocean from Seattle, travelling west of Vancouver Island, and return the same route. Waters might be okay, might be rough. September is the start of storm season for Alaska .

I've been on two Alaska cruises the first week of September, both from Seward to Vancouver. One was fine. The other we crossed the Gulf through a storm in which winds were a few MPH shy of being classified as a hurricane. That was bad. Even many of the crew got sick. The captain had to warn the idiots who were still wandering the hallways (and literally bouncing off walls) to stay in their cabins.

Also be aware that some tours are not available that late in the year. Depends what you're interested in seeing/doing.

The ships are going to be operating somewhere in September and as long as passengers are willing to take advantage of the lower shoulder season fares, many of the ships will continue to sail to Alaska . September is still hurricane season in the Caribbean and it's too early for peak cruise season on the Mexican Riviera so the ships continue their Alaska sailings until it makes economic sense to reposition them.

If you can book your trip for August, you would still have a high probability of a significant rainy weather but the chance of encountering a North Pacific storm with gale-force winds and rough seas is much higher in September.

Visiting Alaska in September: Everything You Need to Know

Thinking about visiting Alaska in September, but not sure if it’s a good time to go or how to start planning?

I want to preface this by saying it’s not too cold to visit Alaska in September! Vibrant fall colors, fewer crowds, unforgettable excursions, abundant wildlife, and (potentially) the Northern Lights await you in the 49th state during the shoulder season. A September trip can be an incredible experience if you know what to expect and prepare accordingly.

In this blog post, I’m sharing everything you need to know about visiting Alaska in September—from a long list of suggestions to keep you busy to what to expect weather-wise. (Keep your eyes peeled for a free packing list at the end of this post!)

What You Need to Know About Visiting Alaska in September

Is September the best time to visit Alaska? That depends! Many would argue that it’s hard to beat an Alaska summer (particularly June and July), and I can’t argue with that. Don’t write off a fall visit, though!

Alaska puts on a spectacular show of fall colors across its dramatic landscapes. To me, experiencing fall in Alaska was worth the tradeoff for slightly less ideal weather than if I had visited during summertime. And not having to deal with bugs was a major perk!

Even though we’re talking about just four weeks, weather and closures vary significantly from the beginning to the end of the month. Early September is an excellent time to visit if you want to miss the summer crowds and experience breathtaking fall foliage before businesses start to close for the season (9/15 is a common cutoff date for many businesses).

It’s only fair that I mention some cons to going during the shoulder season—namely, rain and potential closures of businesses, roads, etc. Closures will depend on when exactly you visit. Nonetheless, you can still plan an epic Alaska itinerary that highlights much of the state’s unparalleled and rugged beauty.

Why Should You Visit Alaska in September?

It’s less crowded: September is considered the shoulder season in Alaska, and it’s not as popular as June, July, and August. This is one of the primary reasons I love shoulder season/off-season travel so much! If you plan it just right, you can hit all the best spots without the crowds.
It’s cheaper: Fewer crowds AND it’s cheaper? That sounds like a win-win to me! By visiting in September, you’ll likely be able to score deals on things like lodging, rental cars, and excursions.
Incredible fall colors: No matter when you visit in September, you should be able to find some beautiful fall foliage in Alaska. I was there in late September, and while it was a little late for foliage in Fairbanks and Denali (north of Anchorage), the colors in Anchorage and along the Seward and Sterling Highways were amazing.
You might see the Northern Lights: This is on everyone’s bucket list, right? It has to be dark in order for the Northern Lights to be visible, which means you won’t see them during peak season due to the long summer days. But September is a great time to see the Aurora Borealis in Alaska!
There’s still plenty to do: Just because it’s the shoulder season and most tourists have left doesn’t mean there aren’t things to do! Honestly, you can find stuff to do in Alaska during any season. Fall is a great time to hit the road, go on a wildlife cruise, hike, fish, and more!

Tips for Visiting Alaska in September

Fly into Anchorage: Anchorage is a great starting point for a fall trip to Alaska! You can pick up a rental car and start your epic adventure by heading north to areas like Talkeetna, Denali, and Fairbanks or south to destinations such as Cooper Landing, Homer, and Seward.
Stay for 1-2 weeks: There is so much to see/do in Alaska, so I recommend visiting for at least 1-2 weeks. Since 9/15 is a common date for more touristy-type businesses to close for the season, the first two weeks of September are an ideal time to visit . This is especially true if you’ve never been before and want to experience as much as possible!
Research/plan in advance: Alaska can be intimidating, which is why creating a plan is a good idea. Also, you may encounter closures, and it’s better to know those things in advance than find out at the last minute. Have a general idea of the route you want to take, make reservations for lodging (this is not necessary for camping in September), and plan out your excursions. This will save you from experiencing a lot of unnecessary stress!

Utilize FB groups: Before my trip, I joined the Hiking in Alaska and Alaska Travel Tips Facebook Groups. Reading about other people’s experiences was extremely helpful! I also used these groups throughout my time in Alaska to get up-to-date information on hikes and road closures.
Pack your rain gear and layers: If you visit Alaska in September, it’s highly likely that you’re going to get rained on. There were a few sunny days throughout my September visit but lots of rain too! I expected this and embraced it. The weather may be all over the place, depending on what areas you plan to visit. Since I traveled down to Homer and up to Fairbanks, I was glad that I packed a wide variety of clothing. Check out my free Alaska packing list for a more in-depth checklist.
Be flexible: I say this for a variety of reasons! If you run into an unexpected road closure or decide you would like to spend more time in a particular area, it’s nice to have some room for flexibility in your plans.
Download an Aurora forecast app: Visiting Alaska in September means you might see the Northern Lights! To increase your chances of seeing the Aurora, you need to be in the right place at the right time. The My Aurora Forecast & Alerts app provides helpful information such as weather conditions (clear skies improve your chances of seeing the Northern Lights) and the Kp index. The scale for the Kp index is 0-9, and the higher the better when it comes to seeing the Aurora.

Things To Do in Alaska in September

If you have concerns about whether there will be things to do in Alaska during the shoulder season, don’t worry! I was impressed at just how many options there were in terms of activities—more than enough to keep me busy every day at each destination.

Go on a road trip

If you’ve never been to Alaska, I think road-tripping is the way to go! Driving around is a great way to experience new places, admire the scenery, and spot wildlife. Find yourself a good road trip itinerary (or make your own), and you’ll be golden!

Whether you rent a car and stay in hotels/Airbnbs or opt for a campervan rental, you really can’t go wrong. I went the campervan route and loved it, and I highly recommend River Wild Campervans .

PSA: Keep your distance when traveling behind/around other vehicles in Alaska. Have you ever heard of an Alaskan windshield? That would be a cracked windshield! It’s common for vehicles to kick up rocks on roadways and cause damage to fellow drivers’ windshields.

Go on a wildlife/glacier cruise in Kenai Fjords National Park

Just two hours south of Anchorage, you’ll find Seward—a charming coastal town in southern AK. There is much to do in the area, but a wildlife cruise is one of the best things to do in Seward. And it’s a good rain-or-shine activity (September is the rainiest month of the year in Seward)!

As you cruise through Resurrection Bay and the Gulf of Alaska, keep your eyes peeled for whales, otters, puffins, bald eagles , and other wildlife! Resurrection Bay is a great place for whale watching , so you’re in for a treat if that’s on your bucket list.

In addition to seeing wildlife, you’ll stop by a tidewater glacier and may have the opportunity to see it calving. If you’re not familiar with glacial calving , look into it! It’s a fascinating phenomenon that occurs in nature.

Chase fall colors

Close up of evergreens and yellow birches

The best place to see fall foliage in Alaska in September will depend on when exactly you visit, but you’ll be able to find signs of fall throughout the state regardless.

If you’re there in early September, you should be able to catch vibrant colors north of Anchorage in areas like Fairbanks, Denali, and Talkeetna. The Alaskan tundra turns bright red, which looks incredible against the evergreens and golden/orange trees, and stunning mountain ranges.

A late September visit isn’t a bad time for fall foliage! Make your way down to Homer via the Sterling Highway or Seward via the Seward Highway, and you’ll see beautiful landscapes featuring snow-capped mountains and golden-yellow trees sprinkled amongst evergreens.

Look for wildlife

Keep your eyes peeled for Alaskan wildlife as you drive around and explore! Binoculars are a must for viewing wildlife. It’s Alaska, so there’s no telling what you might see. Alaska’s Big Five includes bears, moose, caribou, Dall sheep, and wolves.

Consider stopping by the Alaska Wildlife Conservation Center — it’s the perfect way to see wildlife near Anchorage . This animal sanctuary takes in injured/orphaned animals and allows visitors to drive or walk through the property. You can see everything from bears and moose to smaller critters like porcupines! Click here to get your tickets online through GetYourGuide .

I was bummed I didn’t see any bears while visiting in September, but the bear scat I saw while hiking tells me they were definitely around! I saw moose, otters, sea lions, and many birds (including bald eagles).

Wildlife in Alaska is no joke. Animals like bears and moose aren’t out to get you but will defend themselves if they feel threatened. Take safety measures, such as carrying bear spray while hiking, and familiarize yourself with what to do in case of an encounter (particularly with bears and moose). Most importantly, make sure to respect wildlife and give animals their space!

Visit Denali National Park

There are a number of important things to know when planning a fall trip to Denali National Park, but I highly recommend spending some time there while visiting Alaska in September.

There’s one main road in Denali National Park. Before September 15th, you can only drive a personal vehicle to mile 15 (unless you win the Road Lottery , which you must apply for in May). Assuming you don’t win the Road Lottery, you’ll need to hop on a private bus to get past mile 15. After September 15th, however, you can drive a personal vehicle as far as the weather permits.

In late September, I was only able to get to mile 15 (the road was closed at that point due to a winter storm that had rolled in). If I’d been there just a day sooner or later in the week when they reopened the road, I would’ve been able to drive to mile 30. Check the NPS Current Conditions page for updates.

If you’re lucky, you might get to join the 30% club! Less than 30% of visitors see the tallest peak in North America (Denali) because it’s often hidden due to cloud cover. You become part of the 30% club if you’re fortunate enough to see the mountain. On my first day in the area, I saw the mountain at sunset with the thinnest cloud stretching across it. It was magical!

Hike in the Alaskan wilderness

Hiker on the Harding Icefield Trail in Kenai Fjords National Park

If you’re an outdoor lover, you’ll be in heaven in Alaska! The hiking options in Alaska are out of this world. I’m going to highlight a few of my favorites from the areas I visited throughout my September trip.

This list is just the beginning when it comes to Alaska hiking in September! Use AllTrails to find even more recommendations.

Anchorage: Flattop Mountain (one of the best things to do in Anchorage in September if you’re up for a challenge!)
Girdwood: Winner Creek Trail // North Face Trail
Cooper Landing: Slaughter Ridge Trail
Homer: Diamond Creek Trail // Homer Spit Trail
Seward: Harding Icefield Trail // Tosina Creek Trail
Talkeetna: Talkeetna Lake Trail
Denali: Savage River Loop // Mount Healy Overlook

Consider a guided hike if you’re not comfortable hiking alone or would prefer to go with someone familiar with the area! I did this the first time I visited Rocky Mountain National Park, and it was the highlight of my trip.

Fly fishing on the Kenai River

Fly fishing in the Kenai River was one of my favorite experiences from visiting Alaska in September! I had never been fishing before this trip, but I picked up fly fishing in no time because of our knowledgeable guide.

The Kenai River is the crème de la crème when it comes to fly fishing, and I cannot recommend Cooper Landing Fishing Guide enough. They run trips for rainbow trout, king salmon, silver salmon, and sockeye salmon. What you’ll catch depends on the time of year. We booked a half-day fishing trip and caught some beautiful rainbow trout and Dolly Varden.

Get an AK fishing license if you plan to go on a fishing trip. Other than that, the guides at Cooper Landing provide everything you need (rods, waders, wading boots, etc.).

Ride the Alaska Railroad

The Alaska Railroad is one of the best ways to experience Alaska. The railroad operates year-round, making it a great fall (or even winter) activity!

You can choose from various trains/routes (note that not all trains operate year-round), but I recommend the Coastal Classic Train from Anchorage to Seward for a fall trip. The train is the perfect way to take a day trip or a multi-day adventure to Seward.

Throughout the train ride, expect to see breathtaking mountains and spectacular fall colors even into late September. Watch out for wildlife as you travel along the Turnagain Arm coast, and admire the Kenai Mountains as you continue on your southbound journey to Seward.

Another option: Fly into Anchorage > take the Coastal Classic Train to Seward > and go on an Alaska cruise out of Seward.

Take a flightseeing tour

Think Alaska is beautiful from the ground? An aerial view is even better! A flight tour is a pricier experience, but it’s worth splurging. I mean, when’s the next time you’re going to be in Alaska?

What exactly you’ll see/do depends on which tour you book. Regardless, you’ll get a bird’s-eye view of Alaska’s jaw-dropping mountain ranges (and maybe some wildlife!).

Check out the Alaska State Fair

The Alaska State Fair is held yearly from August to early September in Palmer, AK, which is about an hour north of Anchorage.

I wouldn’t go out of my way to go to the state fair because there’s so much more to see and do throughout the state—you have to pick and choose wisely when you’re on a tight timeline. However, it’s worth checking out if you’re looking for things to do in the Palmer area. The fair has great food, concerts, and fun exhibits.

Look for the Northern Lights

Night sky covered by the Northern Lights

The Aurora is yet another reason it’s good to be flexible throughout your trip. If the Aurora forecast is looking particularly favorable one evening, I suggest that you try to spend the night in Fairbanks.

For many reasons (low light pollution, weather conditions, etc.), Fairbanks is one of the best places to see the Northern Lights in Alaska. Click here for more information on viewing the Aurora in Fairbanks .

I saw the Northern Lights in Fairbanks in December 2017 and there are really no words to describe the experience. The way the emerald/violet lights danced and put on a show was unreal!

You’re most likely to see the Northern Lights between 10 pm and 3 am. If you’re not a night owl, you may want to take an afternoon nap to make sure you can stay up late to watch for the lights.

Pro tip: Join the Aurora Borealis Facebook Group for reports on Aurora sightings and check the webcams on The Aurora Chasers’ website.

If you want to increase your chances of seeing the Northern Lights , consider booking a Northern Lights tour with an expert guide.

Best Places to Stay in Alaska in the Shoulder Season

There’s no shortage of scenic towns to choose from—quite the opposite, which makes it hard to narrow things down. Keep scrolling for my thoughts and recommendations on the areas I’ve visited!

Since September is technically the shoulder season in Alaska, you’ll likely be able to score discounted rates for your lodging! Already know where you’re going? Search for a hotel in a particular area:

As for camping, it’s easy to find places to camp in AK during the fall if you can boondock (camp without hookups). A campervan from River Wild Campervans is the perfect way to experience Alaska during the fall because their vans are fully functional off-grid.

Campervan at the Iditarod Campground in Seward, AK

One thing to note: Make sure to check for campground closures . Some places allow camping in the off-season, and others are closed/gated. I like to look at the most recent Google reviews to see if there’s any helpful information. If the most recent review was four months ago, that’s probably a good indication it’s closed/inaccessible.

Map of Alaska

I suggest that you fly into Anchorage to start your Alaskan adventure. This area is the most populated city in AK by far, so it has more of a city vibe than any other town on this list.

While I wouldn’t stay in Anchorage for the duration of my trip (there’s so much more to see in AK!), it’s a great base or stopover point when traveling north to south or vice versa (such as Talkeetna to Seward). Also, the mountain views from Anchorage are 10/10.

Where to stay

Hotel room with a view at Hotel Captain Hook in Anchorage, AK

Hotel: There are a lot of options when it comes to hotels in Anchorage, but Hotel Captain Cook is a classic hotel located downtown with clean, spacious rooms and lots of restaurants/shops within walking distance. [ BOOK HERE ]
Campground: The Cabela’s parking lot is an option if you need a quick overnight stop. Alternatively, Eagle River Campground and Eklutna Lake Campground are both good options for camping in the Anchorage area, and they’re a bit more scenic than the Cabela’s parking lot 😉

Just 45 minutes south of Anchorage, you’ll find Girdwood. Because of Alyeska Resort, Girdwood is a popular year-round destination with a wide variety of things to do, making it the perfect destination for adventure lovers.

Alyeska Resort in Girdwood, AK surrounded by mountains

Hotel: The best hotel in Girdwood is a no-brainer: Alyeska Resort. At Alyeska, you’ll be surrounded by bike paths, hiking trails, a Nordic spa, and more! [ BOOK HERE ]
Campground: Located in Chugach National Forest, Williwaw Campground offers nice campsites with beautiful views and plenty of nearby hikes.

September is the rainiest month in this charming little coastal town, but that doesn’t mean you should skip it! Going on a wildlife cruise and stopping by Kenai Fjords National Park are musts while in the area and doable even if it’s raining.

Harbor 360 hotel in Seward, AK with boats in front

Hotel: The Harbor 360 Hotel is a no-nonsense hotel in the heart of Seward with incredible views of Resurrection Bay and the Kenai Mountains. [ BOOK HERE ]
Campground: It isn’t much and honestly looks more like a parking lot than a campground, but the views of Resurrection Bay from the Iditarod Campground are breathtaking.

Homer surprised me! I wasn’t sure what to expect, but I was floored by the beaches and mountain views. Even in September, there’s plenty to do in Homer, from exploring Kachemak Bay State Park (accessible via boat or flight from Homer) to spotting marine life while walking along the Homer Spit or Bishops Beach.

You can also get to Katmai National Park and Lake Clark National Park (both known for bear viewing tours), which are only accessible by boat or plane, from Homer.

Exterior of the Juneberry Inn in Homer, AK on a sunny day

Hotel: I don’t know about you, but I love a good bed and breakfast. The hosts always have the BEST recommendations. The Juneberry Lodge is in an excellent location (with amazing views!), and the hosts are incredibly kind. [ BOOK HERE ]
Campground: Much like the Iditarod Campground in Seward, Mariner Park looks like a parking lot, but it is indeed a campground with epic views. If you go to the far side of the parking lot (by the water), you’ll see numbered sites with fire pits and picnic tables.

Talkeetna is a picturesque mountain town about 2.5 hours south of Denali National Park. It’s a great halfway point between Anchorage and Denali National Park . This charming little town is a must if you plan to head north of Anchorage when visiting Alaska in September.

Interior of the Talkeetna Fireweed Cabins

Hotel: Not quite a hotel, but the Talkeetna Fireweed Cabins are an excellent option in this area. The cozy cabins are tastefully furnished and include thoughtful amenities like a stocked kitchenette and outdoor furniture. [ BOOK HERE ]
Campground: If you want to be within walking distance of Talkeetna, check out Talkeetna Camper Park (note that you’ll be next to train tracks). Alternatively, you could head north of Talkeetna and camp at Denali View South , which has pit toilets, fire pits, and picnic tables. It’s right off Parks Highway, so there is some road noise, but I didn’t find it overly bothersome.

Denali National Park

I contemplated whether a trip to Denali would be worth it when planning to visit Alaska in September. I decided to go for it, and I’m glad I did. Although I wish I’d been there in early/mid-September to catch more fall colors, I still had a great time in late September. It was fun to drive Denali Park Road as far as the weather permitted (mile 15) and visit the Denali sled dogs.

Exterior of the Denali Tri-Valley Cabins

Hotel : Healy is the closest town to Denali National Park and where you’ll find lodging options a bit more removed from the touristy places to stay outside the park entrance. The Denali Tri-Valley Cabins are a little community of rustic, spacious cabins within 20 minutes of Denali National Park. [ BOOK HERE ]
Campground: Shortly after entering Denali National Park, you’ll pass Riley Creek Campground on your left. It’s a nicely wooded campground in an unbeatable location on Denali Park Road. If you were visiting Alaska during summer, you’d want to make reservations to camp here; however, reservations aren’t necessary from mid-September through early May.

Fairbanks is 6 hours north of Anchorage. After Anchorage, Fairbanks is the next largest city in terms of population. It’s a little out of the way but a great place for viewing the Northern Lights between August and April.

Exterior of cabins at Pike's Waterfront Lodge in Fairbanks, AK

Hotel: There are plenty of hotel chains in Fairbanks, but if you want a more “Alaskan” experience, stay at Pike’s Waterfront Lodge . This rustic lodge will make you feel right at home! [ BOOK HERE ]
Campground: Not far outside the city, you’ll find seclusion at Rosehip Campground . It’s a very peaceful place to camp along the Chena River!

Alaska Weather in September

While September certainly isn’t the worst time to visit Alaska, the weather might not be perfect. Make sure to pack your rain gear and lots of layers (more on what to pack in the next section!) as the weather can be unpredictable.

Not surprisingly (since Alaska is massive), temperatures in Alaska in September vary quite a bit depending on your location. Temps in coastal towns like Seward and Homer hover around the 50s and 60s. On most days, I was comfortable in leggings and a long-sleeve shirt with a fleece or hoodie on top.

Anchorage weather in September is pretty mild with lows in the 40s and highs in the 60s . If you plan to head north to places like Talkeetna, Denali National Park, and Fairbanks, expect clearer skies and slightly cooler weather (lows in the 30s). Early mornings/evenings will be chilly! Knowing what to pack when visiting Alaska in September is crucial.

What to Pack for a Fall Trip to Alaska

Wondering what to wear in Alaska in September? On an average day throughout my trip, I wore waterproof boots , a beanie, leggings, waterproof hiking pants , a long-sleeve shirt, and a fleece with a rain jacket or windbreaker on top. I added/removed layers as necessary to stay comfortable.

Download my free Alaska fall packing list for my recommendations and a checklist!

Items to pack for a fall trip to Alaska (hiking boots, towel, headlamp, wool socks, binoculars)

What to pack in your carry-on

I keep my phone, ID, and wallet in a fanny pack for easy access while traveling. I carry the Lululemon Belt Bag, but I’m linking a dupe since that one is always sold out.

Technology: I always pack my camera gear and laptop in my carry-on, because I don’t want my technology to get damaged. I got this CALPAK backpack duffel a while back and it is the BEST carry-on bag I’ve ever owned (the fact that it’s made out of recycled materials makes it even better). It fits all my camera gear and my laptop perfectly!
Kindle: Traveling with my Kindle gives me something to do when I’m relaxing or don’t have service. It’s a lifesaver for long flights!
Headphones: I keep my AirPod Pros in my carry-on because they’re nice to have in airports/on flights.
Chargers: I tend to lose chargers, and I’ve found that keeping them in a specific pocket in my carry-on helps me keep up with them. Bring a portable charger for days when you’ll be on the go!
Sunglasses : These lightweight polarized sunglasses are reasonably priced and great for outdoor activities!
Reusable water bottle: I like to take a Nalgene with me when traveling. They’re lightweight and inexpensive. I love my Hydro Flask, but I don’t want to lose it when traveling.
Neck pillow: I bought this memory foam travel pillow a few years ago and love it! It’s so comfortable and packs down pretty small.
One outfit: Having a comfy travel outfit in my carry-on makes life so much easier after a long travel day when all I want to do is go to sleep. It’s nice to be able to grab something cozy with ease rather than digging through a suitcase and trying to piece together an outfit.
Small toiletry bag : For the same reasons I like to keep a comfy outfit handy, it’s helpful to have some toiletry basics easily accessible in a small toiletry bag . Just remember these items need to comply with TSA regulations!

What to check in your suitcase

I highly recommend waterproof luggage for a fall trip to Alaska. And remember to leave a little extra room so you can bring home some goodies!

Hiking boots: If you plan to do any hiking, take your hiking boots! Since it rains a lot during fall in Alaska, the trails can get pretty muddy so keep that in mind. I always travel with my Danner Mountain 600s .
Comfy shoes: Bringing a pair of comfortable slip-on shoes is a must when traveling. The Birkenstock Arizonas are my go-tos.
Waterproof boots: I went on a last-minute REI run before my trip to grab these waterproof/insulated boots , and I’m so glad I did. They’re cute and super comfortable, but I recommend sizing up one size (especially if you want to be able to wear thick socks)!

Make sure to pack shower shoes if you’re camping!

Base layers – To keep your skin dry
Mid layer – To keep you warm
Outer shell/rain jacket – To protect you from the elements
Long-sleeve shirts: I recommend bringing at least three long-sleeve shirts for a one-week trip. I’ve been loving the Toad & Co Primo Long Sleeve Crew . The material is so comfortable!
Leggings: I like to hike in leggings , but pack a few pairs of hiking pants (love these!) if that’s what you prefer. You won’t need anything extremely heavy-duty for a fall trip to Alaska, but you might want to bring at least one extra warm pair just in case.
Waterproof pants: These waterproof pants are worth every penny for hiking in the rain. I’ve worn them through pouring rain/sleet, and they’ve kept me dry down to my base layers.
Wool socks: The Darn Tough Micro Crew Cushion socks will forever be my favorite socks for hiking and travel. They’re cushy and moisture-wicking!
Beanie: You’ll definitely want to toss a beanie or two in your luggage for a fall trip to Alaska since it can get pretty chilly/windy.
Neck gaiter: Whether you prefer a neck gaiter or scarf, pack something to keep your neck warm.
Gloves: I put my gloves on a few times after the sun went down. They’re 100% necessary for sitting outside and waiting on the Northern Lights. These are the best waterproof gloves that aren’t too bulky. My husband recommended them to me after using the men’s version while he lived in AK!

Hiking gear

Day pack: A small day pack (I’d recommend something in the 24-40L range) will come in handy for hiking and exploring.
Rain cover: Make sure you have a rain cover for your pack (it’s basically a rain jacket for your backpack). You can buy them separately at REI if your pack didn’t come with one.
Headlamp: You may not plan on doing any hiking in the dark, but it’s still good to have a headlamp just in case.
First aid kit: You should always carry a compact first aid kit with emergency items when hiking!
Quick-drying towel: I highly recommend packing a quick-drying towel . I used mine for sitting on wet benches, drying off after rainy hikes, and showering (since I camped).

Other items

This includes anything you don’t put in your small toiletry bag or stuff that’s just too big for a carry-on. Don’t forget to pack binoculars for wildlife viewing !

As I’ve mentioned several times (because I can’t emphasize this enough), layers and waterproof items are a must when visiting Alaska in September.

Alaska Cruise Weather by Month

Alaska Cruise Temperature by Month

Whether soaking up the golden sun on a fishing expedition or feeling the crisp breeze as you zipline through picturesque landscapes, you may notice that on an Alaska cruise , weather can vary greatly month-to-month. Princess cruise itineraries travel to the Southeast and Inside Passage regions of Alaska from May through September when wildlife is bustling, greenery is flourishing and salmon are running. Temperatures can reach anywhere from the low 30s to upper 80s depending on your month of travel as well as the port of call. We always recommend that you dress in layers to prepare for whatever weather comes your way. To help you get ready for your awe-inspiring adventure, learn about Alaska cruise temperatures by month.

Alaska Cruise Weather in May

After spending the winter in warmer climates, humpback whales migrate north and break the waters of the Inside Passage, marking the dawn of Alaska’s most vivacious season. Hundreds of king salmon grace the majestic waters of the Pacific while freckled lynx bask in the early summer sun. Thanks to the modest daytime temperatures and refreshing evening climates, May is peak season for many of Alaska’s most cherished wildlife. Weather typically ranges from the -1 to a high of around 12 degrees Celsius. May itineraries invite guests to pack jumpers and jackets for easy layering.

Alaska Cruise Weather in June

Feel the warm embrace of the summer sun throughout June when the Land of the Midnight Sun experiences the height of its daylight. With over 18 hours of golden sun each day, Alaska landscapes kiss the snowy surfaces goodbye and welcome the lush green meadows that bear the fruits of winter’s labor. With newly dried surfaces, hiking expeditions commence. As you venture into the depths of Alaska’s wilderness, reach new heights where you can enjoy unparalleled views of staggering glaciers and roaming hillside wildlife. With lows around 5 and highs around 18, allow the revitalising, crisp breeze to tickle your neck as you rejoice in the unforgettable climb.

Alaska Cruise Weather in July

As temperatures continue to rise, relish in the warmest month of the year when Alaska’s wildlife comes out to play. In Icy Strait Point, find regal brown grizzly bears roaming through streams in search of fresh salmon. Or, look for lively humpback whales making a splash off the coast of Juneau. As you embark on your summer adventure, bring light jackets for hiking through shady regions as well as plenty of sunscreen for basking in 18 hours of glorious sunlight each day this month.

Alaska Cruise Weather in August

Cast your line into the marvels of an Alaska summer by cruising in August. As you sail into each port of call, delight your taste buds in the delicacies of Alaska’s waters. Donning subtle notes of the sea, the silver salmon is one of the most sought-after fish and just so happens to be most fruitful this time of year. Whether or not fishing is your forte, be sure to pack water-resistant apparel for every splash and sprinkle that may arise from kayaking down crystalline fjords and hiking through misty rainforests. With lows around 5 and highs of around 18, you’ll feel refreshed and eager to explore the captivating wonders of Alaska.

As September begins, the sun dips below the horizon signifying the inauguration of autumn. The lush green forests transition into vibrant hues of gold and saffron while the mountaintops become freckled in snowfall. Daylight quietly recedes and the growing twilight perfectly contrasts the luminous green lights of the Aurora Borealis . The enchanting colours invite you to marvel at the miracles of Mother Nature that so often act as the inspiration for treasured postcards. With only 12 hours of sunlight, temperatures range from around 6 degrees to around 12 degrees. These new, cooler climates encourage Alaska’s famed wildlife to begin preparing for hibernation. Gaze at the water’s surface as thousands of bald eagles congregate to enjoy the final salmon of the season.

Best Month to Take an Alaska Cruise

What is the best weather for an Alaska cruise? Temperatures can vary anywhere between 30 to 80 degrees throughout the summer travel months – inviting guests to layer on the jumpers and windbreakers as weather can be unpredictable. So, the best month to travel to the Great Land depends on what you want to do. For the fishing aficionado, consider May when king salmon reach their greatest appearance. If you prefer to explore the lush scenery by foot, wait until June when the sun has overcome the frosty terrain of the Inside Passage and trails are primed for adventures. Regardless of which month you choose to explore Alaska, you’ll encounter iconic marine life and embark on heart-stirring adventures when you set sail with Princess.

A Primer on Alaska by Month: When to Go & Why

Alaska is huge and weather is vastly different in the north vs south or interior vs coast. And while the primary Alaska travel season is short, conditions can vary greatly between spring, summer and fall. Combine all this with Alaska’s notoriously unpredictable weather, and it can be a challenge to determine a single best time to visit Alaska.

That’s where our experts come in. The guide below is one piece of the puzzle to help you determine the best month to visit Alaska. We outline Alaska weather by month and answer questions such as “When is summer in Alaska?” and “What month is the best time to visit Alaska?” or “When is the best time to go to Alaska?” But our firsthand experience and one-on-one conversations can fill in the gaps. So don’t hesitate to contact us.

Note that in the guide below you’ll see us referring to Coastal, Interior and Arctic regions:

The coastal region includes Southeast Alaska and the Alaska Inside Passage and Glacier Bay , Southcentral Alaska including Prince William Sound, Anchorage, Kodiak Island, as well as coastal Katmai National Park and the Aleutian Islands.
Interior Alaska is the region north of Anchorage up to the Brooks Range just north of Fairbanks and includes Denali National Park .
Arctic Alaska includes the Brooks Range north to the Arctic Ocean.

And while, of course, Alaska is open for travel year-round, the primary tourist season begins in June and ends in August. But our Alaska by month travel season calendar below starts in early spring, because that is when the cruising season kicks off in some of Alaska’s lower, warmer latitudes.

We hope this guide helps you make the most of your Alaska summer vacation . For even more information and detailed climate tables, view our Alaska climate page .

April in Alaska

Small Alaska cruise ships begin plying Alaskan waters as early as mid-March, with most early spring departures running regularly starting in mid-April. Early spring offerings center on Alaska Inside Passage cruise itineraries, with most spanning a week. During this time, you can also consider a longer cruise, traveling with small ships positioning from Seattle, Washington up to Alaska. Nights are still long enough to possibly see the northern lights , while days are getting longer and animals are beginning to stir. The annual early spring Pacific herring migration makes for optimal wildlife viewing opportunities, as humpback whales and orca seek out the abundant fish. Hungry bears awake from hibernation and also go looking for food. Snowcapped peaks drive mountain goats and other creatures to the shoreline to forage. And waterfalls are copious as they gush down fjord walls.

Alaska Weather in April:

Coastal temperature in Alaska in April: 30-45 degrees & 11 hours of daylight
Interior temperature in Alaska in April: 15-40 degrees & 14 hours of daylight
Arctic temperature in Alaska in April: -10-5 degrees & 16 hours of daylight

Benefits of Alaska Travel in April:

Travelers in April and early spring will find lower prices & Alaska travel deals
April & early spring have Alaska to themselves with non-existent crowds
Increased offerings for themed cruises & onboard special guests
Longer northbound positioning cruises from Seattle to Alaska
Dark nights may show northern lights

May in Alaska

May is considered Alaska’s spring and early shoulder season. Many small ship cruises begin operating, but with kids in school, you can still feel like Alaska is all yours. The Inside Passage remains the focus as many more cruise departures start in earnest, as well as opportunities for longer sailings from Seattle to Alaska, passing British Columbia along the way. May is one of the driest months and an optimal one to view wildlife awakening, with lots of babies being born, spring migrations ramping up, snow melting and the landscape budding. Land tours are beginning but National Parks in Alaska’s interior are still closed. Mid-month, the shops and attractions also return to life after a winter slumber.

Alaska Weather in May:

Coastal temperature in Alaska in May: 40-55 degrees & 16 hours of daylight
Interior temperature in Alaska in May: 30-55 degrees & 18 hours of daylight
Arctic temperature in Alaska in May: 15-24 degrees & 22 hours of daylight

Benefits of Alaska Travel in May:

On average the month of May has the least amount of rain
Travelers in May will find lower prices and Alaska travel deals
May has fewer tourist crowds than the prime summer months

June in Alaska

June is when the Alaska travel season comes into full swing, especially in the latter part of the month, and marks the beginning of the best time to visit Alaska. Glacier Bay cruises are in full swing. Cruises in the Southcentral and Southwestern part of the state begin operating, offering adventures along Prince William Sound, Kodiak Island, Katmai National Park and the Aleutian Islands. Some departures even focus on the Arctic waters of the Bering Sea, bringing guests ashore at various points along Russia’s Siberian coastline—you might even spot a polar bear on Wrangel Island.

June is the month to begin taking land trips in Alaska. The Denali National Park road opens (learn more about visiting Denali National Park ); bear viewing in Katmai is optimal with various salmon runs underway; the Kenai peninsula (including Kenai Fjords National Park) is lush with greenery; and the weather is more reliable for flightseeing, floatplane rides, scenic Alaska railroad trips and other special modes of transit for reaching remote wilderness lodges.

Alaska Weather in June:

Coastal temperature in Alaska in June: 40-60 degrees & 18 hours of daylight
Interior temperature in Alaska in June: 50-70 degrees & 20 hours of daylight
Arctic temperature in Alaska in June: 29-38 degrees & nearly 24 hours of daylight

Benefits of Alaska Travel in June:

Longest daylight hours make active wildlife & ample time for exploration
Denali National Park & other interior parks open
Popular towns such as Juneau, Sitka, Anchorage & Fairbanks are in full swing

Birds: optimal seabird & alpine bird rookery viewing
Land: caribou, mountain goat kids, black bear cubs, moose calves

July in Alaska

For many people, the answer to the question “When is the best time to go to Alaska?” is July. With wildlife fully active, all trails accessible, long days and Alaska’s warmest average temperatures, July can be the best month to visit Alaska. This translates into a busy time for The Great Land, with a swell of visitors. Small ship cruises during this busy month mean you can still enjoy areas inaccessible to the large cruise ships, such as Kake and Wrangell Narrows; plus, weather won’t affect your ability to access key Alaskan cities like Sitka. Land tours, averaging 5-8 days, set you up to thoroughly enjoy some of Alaska’s best national parks during this ideal month. If you are planning travel to Alaska in July, then plan ahead and book early.

Alaska Weather in July:

Coastal temperature in Alaska in July: 50-65 degrees & 18 hours of daylight
Interior temperature in Alaska in July: 50-70 degrees & 19 hours of daylight
Arctic temperature in Alaska in July: 33-45 degrees & nearly 24 hours of daylight

Benefits of Alaska Travel in July:

Opportunities for cruise & land tour combinations continue
Long daylight hours make active wildlife & ample time for exploration
Alaska’s warmest temperatures of the year occur in July
Spawning salmon means ideal fishing

Must-See Alaska Wildlife in July:

Water: prime month for humpback whales, salmon runs, sea otters
Birds: puffins, shorebirds begin migrating (millions of birds possible in a flock)
Land: black & brown bears (including grizzlies); mountain goats

August in Alaska

August is a popular time to visit Alaska and marks the end of the high travel season. Increased moisture improves the vibrancy of an already verdant landscape. Midway through August, colder temperatures encourage brilliant fall foliage, especially in the interior and Denali National Park. Wildlife remains in abundance and all Alaska small ship cruises and Alaska tours are operating on a regular basis. As the month winds down, so do the number of travelers to Alaska, with a shift in weather that signals fall has arrived.

Alaska Weather in August:

Coastal temperature in Alaska in August: 50-60 degrees & 18 hours of daylight
Interior temperature in Alaska in August: 45-65 degrees & 18 hours of daylight
Arctic temperature in Alaska in August: 33-41 degrees & 20 hours of daylight

Benefits of Alaska Travel in August:

Cruise & land tour combinations
Ideal fishing conditions (halibut, rainbow trout, northern pike, salmon)

Must-See Alaska Wildlife in August:

Water: beavers, humpback whales & orca,
Birds: peak songbird migration, bald eagles, loons
Land: caribou, black & brown bears (including grizzlies)

September in Alaska

September brings Alaska’s fall shoulder season, with fewer visitors and often Alaska special offers. Longer nights again bring possible opportunities to view the aurora borealis. The cooler weather turns trees and tundra into explosive fall colors of red, gold and purple. Snow begins to dust mountain peaks. Animals are busy preparing for the oncoming winter—migrating, mating, marking territory, hunting and foraging for food—which increases your odds of viewing all manner of wildlife. September marks the end of the Alaska travel season and is the best time to travel to Alaska for low prices and Alaska travel deals.

Alaska Weather in September:

Coastal temperature in Alaska in September: 40-55 degrees & 15 hours of daylight
Interior temperature in Alaska in September: 35-55 degrees & 17 hours of daylight

Alaska Must-See Wildlife in September:

Water: gray whales, harbor seals, sea lions
Birds: gulls & raptors begin migrating, bald eagles, black oystercatchers
Land: elk, moose, caribou, deer

October & November in Alaska

Late fall in Alaska is not known for cruises and land tours. Weather is wet and increasingly cold. Alaskan wildlife and Alaskan residents are preparing for the cold dark winter to come. Specialty tours and fishing can attract hearty travelers and custom tours can be arranged.

Winter in Alaska—December Through March

Winters in Alaska can be harsh and beautiful. Weather is extremely cold and storms are severe. Winter activities such as dog sledding, snow shoeing and skiing are possible. A popular attraction during Alaska’s winter is viewing the northern lights (aurora borealis). Specialty lodges offer comfortable accommodations for hearty travelers willing to brave cold long nights to witness this spectacle of nature. What’s the best time to cruise Alaska to see the northern lights? Look to our dedicated page on northern lights cruises for tips and best places to spot the aurora.

Best Time to Cruise Alaska

The Alaska cruising season begins in March and ends in October. The peak season with best weather and wildlife occurs during summer months. It’s then that travelers will find the best combination of long days, good weather and abundant wildlife, including greater numbers of whales that congregate in predictable feeding pods putting on quite a show. But spring, when Alaska awakens from a long winter, is also another favorite time to cruise Alaska. Snow is present in the mountains, driving hungry bears down to the coast for a meal. Small ships, which can sail close to the shore, take advantage of these springtime encounters. April and May are the driest months along Alaska’s coast and there are fewer crowds in both town and on the water. You will find the best prices of the year on small boat tours of Alaska as well at this time.

As Alaska small ship cruise experts, we advise clients that the best time to cruise Alaska is May 15 through September 1. If we had to choose one, the best month for an Alaska cruise is July.

Typically, there are no scheduled cruises from mid-October through February, but special Alaska charter cruises can be arranged during this time with advanced notice. Families typically visit mid June through mid August. View the best Alaska cruises for families . See our monthly Alaska weather tips and travel advice above to find your best time to take an Alaskan cruise.

Best Time to Travel to Alaska by Land

Alaska’s interior is colder than the coast so the land-based travel season can be shorter than the cruising season. Keep this in mind if you are planning an Alaska small ship cruise and an Alaska land tour combination.

Summer in interior Alaska is short and occurs from mid-June through late-August. Winter in Alaska sees far fewer travelers with December through March being the best months to view the northern lights . The spring and fall months in Alaska offer unique opportunities and lower prices.

In our opinion the best time to travel to Alaska is in June, July and August. The best month to visit Alaska is July, when travelers will experience the best combination of weather and wildlife. See our breakdown of Alaska weather by month above to learn more about the temperatures, sunlight and wildlife, to find the best time to visit Alaska for you.

Alaska Whale Watching Season

Whales can be seen from small ships to Alaska throughout the small ship cruise season of May through September. Orca and minke whales are residents so they may be found at any time of year. But most travelers want to see humpbacks and if you fall into this category, then you must plan your trip accordingly.

When to see humpback whales in Alaska? The first humpbacks begin to arrive in Alaska about late April and early May. These are typically the adult males that can make the long migration the fastest. They are followed by younger males, females and finally mothers with calves arriving in late May and early June. Small ship cruises in May will likely view whales, but they will be individuals or smaller groups of two or three spread about looking and waiting for food.

When is the best time to see whales in Alaska? The best time to cruise Alaska for whales is from mid-June through mid-August.

By mid-June most humpbacks have arrived and they are gathering together in predictable feeding pods. This is the best time for whale watching in Alaska and the consistent sightings will continue through mid-August when the first whales will begin to leave for warmer waters. During this best time to see humpback whales in Alaska, sightings are almost guaranteed.

Why is mid-June through mid-August on an Alaskan cruise the best time to see whales? Sunlight from long midsummer Alaskan days causes a bloom of phytoplankton (tiny plants) which serves as the base of Alaska’s rich marine food chain. Strong currents bring nutrients from deep below to mix with oxygen-rich water near the surface resulting in huge blooms of zooplankton (tiny animals), krill and small fish such as capelin, candlefish and herring.

For more insights into seeing whales on your expedition cruise , including tips on where to spot whales, how to prepare and the advantages offered by small ships, read our primer on whale watching in Alaska .

Alaska Mosquito Season

Mosquitoes, sometimes jokingly referred to as the Alaskan state bird, are a fact of life during the summer travel season. But they are more annoyance than deterrent so don’t let bugs affect your travel plans. Mosquitoes and other bugs are most prevalent in the boggy interior and Arctic tundra regions during mid-summer. Populations spike in late June and dissipate in early August. They can’t fly in a light breeze and they aren’t as active in rain, which keeps coastal and mountainous regions relatively bug-free.

You will not encounter bugs on small ship cruises, except when venturing ashore on calm days and even then, they are seldom troublesome. Your packing list should recommend remedies to repel bugs and long-sleeve clothing to keep them at bay when they are encountered. Being equipped for weather and conditions will make your Alaskan experience more enjoyable.

Weather & Packing for Alaska Travel

Weather in various Alaska destinations is unpredictable and travelers should prepare themselves for a range of conditions, no matter what month you travel. We have developed comprehensive Alaska planning guides for our booked clients, with expertise culled from years of our own living, working, guiding and traveling in Alaska.

Prepare for a range of conditions, no matter what month you travel.

Layers are essential for a comfortable Alaska vacation, using fast-drying wicking materials. A raincoat and rain pants are also must-haves, as is a warm hat and gloves. Many boats and some lodges will provide rubber boots. With a well-packed bag, you can appreciate the opportunities created by varying weather, which in turn creates the cornucopia of landscapes and wildlife that brings travelers to the Last Frontier.

Checking the Weather Before Your Trip

Many travelers incessantly check the daily weather in Alaska as their trip approaches. We advise you to resist this temptation, it will only drive you crazy. Local forecasts in Alaska are astoundingly inaccurate and weather changes by the hour. Checking daily forecasts does little to help you prepare.

Stick to the broad guidelines above and as previously stated, follow the advice of your packing lists. Checking the weather before your Alaska trip will only serve to frustrate your preparations and offers little insight into what conditions will be like when you arrive.

Timing & Latitude in Alaska

While this Alaska by Month guide is a valuable resource for planning when to go, wildlife and weather can never be fully predicted, especially in a land as powerful as Alaska. Life in Alaska is greatly affected by latitude variances, as slight latitude shifts can result in big seasonal and light changes. The nature of small ship cruising is to be flexible and nimble, and this ethos should be applied to any trip in Alaska, by land or sea. After all, the surprise in what you experience while in Alaska is a big part of the fun.

So, When is the Best Time to Visit Alaska?

Considering everything stated above, we advise travelers that June 15 through August 15 is the best time to go to Alaska. But not everyone can schedule their trip during this time and as we’ve noted, each season has its benefits. If you plan your trip during the peak season, then plan ahead and book early as these are the dates that sell out first.

If you like this guide to the best time to visit Alaska, you’ll love our comprehensive travel planning services.

My husband and I want to see the Northern Lights. What month is best for clear skies and best viewing. We wanted to go in March but the Borealis Basecamp is already booked. Is April a good month. or is the snow already melting which would hamper dog sledding? Is February too cold?

Hi Vicki, thanks for your question. April is on the tail end of Alaska’s aurora season. If your ultimate goal is to see the lights, going earlier in winter is the best time. February can be quite cold, but it often brings dark clear skies, ideal for seeing the Aurora. If you’re flexible with dates, late February to early March might be a good compromise. There are a number of other remote lodges and tours out of Fairbanks that you may enjoy. Contact us directly to speak with a specialist who can check availability and craft a custom Northern Lights vacation that’s right for you.

Hi, my birthday is at the end of October, and I want to see the northern lights, is October a good time to see the northern lights and what’s the best place?

Hi George, In Alaska, viewing the Northern Lights is possible in October. Typically, there are no scheduled small ship cruises from mid-October through February, so traveling inland for a tour in Fairbanks and areas more north are your best bet in this region. We offer custom tours in Alaska and can offer October recommendations that fit your goal.

For the ultimate birthday celebration, head to the Arctic for the Northern Lights. Our northern lights cruises in Greenland and Iceland are focused in October for best chances of witnessing.

Hello, This was very informative. My friends & I are cruising to Alaska June 4-16,2024. Our first time and my bucket list. I’m hoping to have the trip of a lifetime. I’ve been trying to come see Alaska for 40+ years. I’ve watched the commercials on TV and know it’s going to be amazing. Can’t wait. Can you help me with packing? How much & what? Thanks so very much. Janis A. Jones Coming from Maryland by way of California

Thank you Janis, and congratulations on your upcoming trip to Alaska! It will be well worth the wait.

I am taking a cruise by Norwegian cruise line and I was wondering when is the best time to come to see all the sites my friend wants to see the northern lights if possible can you tell me when to come? I appreciate it. Thank you very much.

Hi Mike, The best time to see aurora borealis in Alaska is during the winter, but the cruise options during that time are slim. To better your chances of seeing the northern lights via Alaska cruise, search for trips with departures as early or late in the cruising season as possible: typically March or late September or October. Learn more about Alaska northern lights cruises on our dedicated northern lights cruises page. Have a great trip.

Will I need a heavy coat in september

Hi Esther, thanks for your question. During September in Alaska temperatures and conditions vary across regions. At the beginning of the month, you’ll likely have fall-like conditions, but it is a short fall. As the month progresses temperatures drop. By late September you will want thicker clothes and a winter jacket. It can also be colder at higher elevations, on a boat, and during morning and evening hours. Layering is essential, so we always recommend inner layers with a combination of a fleece layer then waterproof layer you can remove.

Alaska is on by my bucket list, for one reason is the northern lights, I want to see as much as possible when I come. Either by plane, train, boat, or bus. I may never get but one trip so when should I come or do you have any suggestions?

Thanks for your question, Denise. The best time to go to Alaska really depends on your focus. For prime Northern Lights viewing you should visit during the dark winter nights from November through March. If you want a well-rounded winter trip, visit a specialty lodge for Northern Lights. For the best Northern Lights cruises , consider instead traveling to the Arctic.

But to get the most out of your Alaska trip with great weather, wildlife, longer daylight hours, and have the potential for Northern Lights, you could take an Alaska small ship cruise in the fall, then continue north to Fairbanks, where the Northern Lights begin showing themselves in late August and early September. We offer custom crafted tours in Alaska so contact us if you are interested in speaking with an Adventure Specialist.

I loved all of the info on this post. Thank you. This will make my preparations more accurate. Knowing the weather, daylight hours and wildlife information is a tremendous help.

Glad we could be of assistance, Sherri! Our experts have lived, worked and explored Alaska during every season. Have a wonderful time on your trip in Alaska! If you need further trip planning assistance don’t hesitate to contact us .

I am planning an economic run in my Mitsubishi Mirage to see as much of alaska as possible by car. I’ll be planning late September as I wish to see the northern lights as well during this trip. Trip starts in Texas, my home state. Will the roads be passable around that time for small front wheele drive cars, or should I plan this in early August?

Hi Royce, What a long and exciting trip! Weather can be very unpredictable year-to-year in the fall in Alaska, and services associated with the busy summer tourism season will be winding down. We’d recommend contacting a AAA chapter in Alaska to get some more road-trip guidance. Our expertise is in guided trips and small ship cruises, so for travelers wanting to take in aurora borealis on a ship, we recommend our Arctic-based Northern Lights cruises .

This has been very informative as I want to plan a trip to Alaska. I want to be able to visit the Glaciers, National Parks as well as the Arctic Area.

Can’t wait to travel to Alaska this coming August

You’re in for a real treat, Barbie! August in Alaska is a great time to see humpback whales, orcas, bears and other wildlife as they capitalize on salmon runs. Have a great time.

Hi, I’m a senior with limited walking. I’m hoping to take a cruise the beginning of August. Will I enjoy cruising without a lot of side excursions. Thank you

Hi Patty, There is an Alaska small ship cruise for every style of travel from active to relaxed. Many travelers remain on board to enjoy scenic wilderness cruising from the ship. Travelers with limited mobility may also seek a small ship with an elevator to make moving around the boat easier. Consider Exploring Alaska’s Coastal Wilderness aboard the 100 guest National Geographic Quest or Venture . Small ships cruise close to shore where bears, moose, eagles, and wildlife are easily spotted (bring your binoculars). Flexible itineraries mean small ships can stop and linger longer when whales are spotted. Contact our experts for a full consultation on your perfect Alaska trip and small ship.

My name is Sonya, and I really want to be brave and travel to Anchorage and other parts of Alaska in mid February,2022. Are there many things to see and do at that time or would you recommend another time? I was really hoping to see the Northern lights if possible. Please help guide my decision. Thanks in advance for the advice.

Hi Sonya and thanks for your question. While the northern lights (sometimes called aurora borealis) occur year round in Alaska the best time to view them are dark nights November through March. February is cold and clear, making it an excellent time for northern lights viewing. March is also nice with dark nights but a bit more daylight. We’d recommend getting farther north to Fairbanks and away from the city lights for the best aurora viewing. Stay up late as the best viewing is from 10am-3am. Some lodges can arrange for a wake-up call if/when the lights do come out. If you plan on spending 5-7 days in Alaska with a least 3 nights looking for the lights you’ll have a 90% of seeing them. Remember the lights need to be out and you need clear skies. The aurora can be elusive so think of it as an adventure. But the payoff is one of the most incredible spectacles of nature. Finally you can check the aurora forecast from the University of Alaska Fairbanks. There are a host of winter activities available such as the Alaska Railroad, hot springs, dog sledding, snowmobiling, skiing and snowshoeing. We offer custom crafted winter tours in Alaska so contact us if you are interested in speaking with an Adventure Specialist.

We want to travel summer 2022, fly into Anchorage and travel north and south from there. I’m concerned about it raining if we come in late July into August. Does it rain constantly, or do you have brief showers like Hawaii?

Hey Karen! “Unpredictable” best describes Alaska’s weather. Throughout the summer, weather is variable and can change rapidly. Alaska is a rainy destination, so you are likely to encounter rain at some point during your trip no matter what summer month you choose. In Anchorage and Denali rain showers and the chance of storms, with more than just showers, increase as the summer progresses. See the above Alaska climate tables for rainfall by month.

Our clients are prepared with an extensive packing lists and travel preparation. Pack the right gear, prepare for rain and if you get lots of sunshine, it’s a bonus! May and June are considered the “driest”, but even then there’s always a chance of rain on any given day. Feel free to contact our Alaska travel experts for further assistance. They have lived, worked and explored the region in depth as former guides, operations managers and naturalists, and can help you craft the perfect Alaska package.

Hello, and thank you for this wonderful information. My husband and I would like to fly in from Arizona. We are not big into city life, noise pollution, bright lights and lots of people. We love nature and I am a photographer. We love the fall and moderate hikes. Where would you suggest we fly into, as well the areas of beautiful Alaska, that you would suggest, based on our interest.

Hi Nancy, I’m glad our post helped you decide that fall is the best time to visit Alaska. Our full-service trips showcase the best of Alaska, with plenty of nature, hiking and photography opportunities (as evidenced by our small ship Alaska cruise reviews and Alaska tour reviews ). Fly into Juneau, Sitka, Ketchikan or Petersburg for Southeastern Alaska’s Inside Passage. And fly into Anchorage to access Prince William Sound, Denali/Katmai/Kenai Fjords National Parks and Kodiak Island. To help narrow your options, consider our Alaska Cruise Guides (and our picks for 5 iconic Alaska wildlife cruises ) and how to visit Denali National Park . An Adventure Specialist will be in touch soon to discuss fall options and better hone in on your ideal trip.

Hello, I wanted to catch beautiful fall foliage in AK as well. I’m planning to go there in 2nd week of September. Will that be too late for fall foliage? We also would like to check out some national parks as well and definitely wildlife sightseeing and finishing. We also will visit some old friends who live in Dutch Harbor. We will be staying in Airbnb, rent a car to drive around. Should we land in Anchorage airport for our convenience ? We are from Sacramento, California. Please give me some ideal here when go go, should we stay in Anchorage for few days then take off to Dutch Harbor? Please advise. Thank you. Sincerely, Yen

Hi Yen! That will be quite the adventure! The remoteness of Dutch Harbor, part of the Aleutian Islands, fits our hallmark style of small ship cruising perfectly. September is a great time to see Alaska’s fall colors and Anchorage is a perfect central hub to explore from. It offers many ways to enjoy the surrounding national parks plus flight connections to Dutch Harbor. The earlier in September you go the less likely you will have to deal with snow conditions and will have more options for cruises and Denali National Park tours . As a full service tour operator we’re here to help you arrange the seamless vacation of a lifetime experiencing the best of Alaska up close and in style. Contact us to talk about the benefits of our expertise.

We are traveling to Alaska the second week of October 2022. Our only nailed down event is a wedding in Glacier View mid week. We are avid hikers and would love to see the National Parks in any aspect. We will likely rent a car and also looked at winter trains. We thought we’d start in Anchorage, hit Glacier View, Wragnell, Denali, then back to Anchorage. Is this doable?

Hi Emily, A self-drive trip is do-able in the late fall. Be aware though, that by October 1st Denali National Park begins to wrap things up. Tours, lodges, shuttle buses, Visitor Centers, Ranger Stations and campgrounds are all closed. Because late fall season DIY trips are largely based around weather conditions, we recommend directly contacting the parks you wish to visit in the fall to get an update before traveling to them.

Winter arrives early to interior Alaska so there can be snow on the ground by the end of September or early October. Take a look at our Alaska climate page to see the rainfall averages and daylight hours in October. We focus our Alaska cruises and land services during the primary tourist season from May through August but can help with custom tours during the fall–contact us if you are interested.

Hi, we are planning a trip to Alaska and have specific things we would like to experience.. Northern Lights, wildlife, beautiful color changes would be on the top of our list. We have special travel needs that need to be addressed as well, one wheelchair bound guest and another is 100% service disabled veteran. We also travel with service animals (2 dogs). Do you have any suggestions pertaining to our situation to guide us in our plans? Thanks in advance

Hi Tammy, Sounds like early fall would be the best time for your Alaska trip. The easiest way to check most of your boxes would be a land viewing rail tour. The Alaska Railroad’s passenger trains are wheelchair accessible and service animals are welcome. From the train you can enjoy Alaska’s fall colors between Anchorage and Denali, stop in Denali for incredible wildlife, then continue north to Fairbanks, where the Northern Lights begin showing themselves in late August and early September. Before the land tour, you could also consider adding a cruise component for even more up-close wildlife opportunities. Fall colors in Alaska last only a few short weeks so timing with Northern lights can be tricky, but with a little luck, Alaska will provide. An Alaska specialist will be in touch soon to discuss Denali-based Alaska tours , potential small ship Alaska cruises , or a custom travel arrangement to cover both.

My husband and i are planning a cruise this coming year. My biggest goal is to see whales. When is the best time for whale watching. Thank you S.D.

Hi Sharon, Whale watching aboard an Alaska small ship is a spectacular goal! Our guide to Whale Watching Aboard Small Ship Cruises in Alaska recommends mid-June through mid-August, although whale sightings are possible throughout the season. Most of our small ship Alaska cruises offer opportunities to see whales. One of our Alaska Adventure Specialists will be in touch soon to discuss a trip that best suits your whale watching goals.

Hello, I want to see the ice caves, but flights in summer are too expensive for me. Can you suggest any other time?

Hi YM, You’re likely referring to the Mendenhall Glacier out of Juneau, Alaska, which our team has experience visiting, but mostly en route to Alaska small ship cruises or other adventures in the Southeast Alaska region. While we’re not experts on ice caves, and conditions can vary any time of the year, the ice is most likely more stable (but the temperatures still bearable for travel & flights less expensive) in the spring and fall. Contact us to discuss planning and booking an Alaska trip like this further if you wish! Just know that our expertise is in adventure travel packages built for you to see the best of Alaska vs. day trips.

Hello, and thanks for the info. Do you know what time of year is when mosquitoes are all over?? Or is there any condition when they are not that annoying?

Hi Sergio, Mosquito density in Alaska varies by month and location. On Alaska small ship cruises there is no need to worry about mosquitos, but inland Alaska land tours do experience them, particularly in Denali National Park. To avoid inland mosquitos, travel outside of July and the first half of August. If you’re aiming to combine a land tour with a cruise, however, consider that whales are in abundance during that time. Contact one of our Alaska specialists to help you pinpoint the optimal timing for your Alaska trip .

So I am trying to plan our first trip to Alaska next year – Flying into Anchorage, renting a car and seeing Homer, Seward and Denali. Just can’t decide what is the best month. We were thinking June 4-13, 2020. Is there snow on the mountain peaks still at this time? What do you think would be the best time to visit? We would to see snow covered mountains! 🙂 We’re from Florida (the Panhandle where Hurricane Michael hit last Oct) 🙁

Thank you so much! Wendy Chambers

Hello Wendy, As you read in this post, every month offers its benefits and as we know about weather, in Alaska especially, it can be quite unpredictable. Depending where you are in Alaska the snow on the mountains can last through the year, but the earlier in the season the better! If you need any assistance booking, we have incredible Alaska tours , in addition to our small ship cruises , that get you deep into the wilderness of Denali, Kenai and other incredible Alaska destinations. We are so sorry to hear you were hit by the hurricane, we hope for a speedy recovery to you and your community!

Thanks for the well organized post which answers some planning questions on travel in Alaska. It saves me some research time, and serves as a focus to refer to as I weigh the options.

“There is no best time to cruise Alaska. The nature of small ship cruising is to be flexible and nimble, and this ethos should be applied to any trip in Alaska, by land or sea. Afterall, the surprise in what you experience while in Alaska is a big part of the fun.”

I appreciate your summarizing statement, as it confirms for me that booking with adventuresmithexplorations is the right choice!

Alaska in September: Weather, Things to Do, and What to Wear

Not sure if a trip to Alaska in September is the right choice for you? Well, every month in Alaska has something incredible to offer, and September in Alaska is no exception!

September marks the start of fall in Alaska. The air is crisp and the crowds are gone. I love being in Alaska at this time of year to watch the foliage transition from green to vibrant shades of yellow, orange, and red.

Around mid-September, many tour operators close for the season, but there are still plenty of things to see and do on a vacation in Alaska in autumn. The night skies return, providing visitors a chances to see the Northern Lights.

If you’re considering a September trip to Alaska , this guide will tell you everything you need to know to decide if this is a good time to visit. I’ve included information about the weather, daylight hours, events, what to pack and wear, and some of my favorite things to do in September.

5 Reasons to Visit Alaska in September

Fall foliage. The vibrant colors are stunning!
Aurora season has begun. The skies are finally dark enough to see the Northern Lights.
It’s shoulder season. This means less crowds and cheaper prices.
The air is crisp . It’s sweater weather, the fireplace is lit, and it feels very cozy.
Enjoy the trails. Less people means you can hike in solitude.

Weather in Alaska in September

Daylight in september.

Daylight hours in September will see a huge decrease from August with about 14.4 hours of daylight in Fairbanks. Anchorage sees about 14 hours and 24 minutes of daylight in September. In Juneau, you’ll experience about 12 hours of daylight and 12 hours of darkness, with sunrise at 6:59 a.m. and sunset at 7:10 p.m.

Aurora Viewing in Alaska in September

Shorter days and dark skies increase your chances to see the aurora borealis . Aurora Season began in late August and your best chance of seeing the northern lights in Alaska in September is in the Interior region.

Rain in Alaska

September is the rainiest month of the year in Alaska. Last year, Anchorage had one of the top 15 wettest years on record . You should expect to experience wet conditions throughout the month, but that could mean anything from a quick drizzle to pouring rain. Interior Alaska typically sees less rain than the rest of the state.

Temperature in September

September brings cooler temperatures in Alaska . Average daytime highs range from 50°F in the Arctic to mid 50s F in the Interior. Nighttime lows drop below freezing in the Arctic and between the 30s F to mid-40s F across most of the state. By the end of the month, it’s possible to see snow on the mountaintops!

Here’s what you can expect in different cities around the state:

Average temperature in Anchorage, Alaska in September: 55°F (13°C)
Average temperature in Fairbanks, Alaska in September: 55°F (13°C)
Average temperature in Juneau, Alaska in September: 63°F (17°C)

Best Things to Do in Alaska in September

September brings the perfect balance of daylight and darkness. In the first half of the month, visitors can still enjoy summer tours and activities. By the end of the month, most tour operators close for the season and some small towns around the state go quiet.

As the season changes, here are some fun things to do in Alaska in September:

Scenic Fall Drives

Fall in Alaska is quick but beautiful! The trees turn yellow and orange and the tundra turns red, which is the perfect recipe for pretty photographs. The best part is that you can enjoy peak fall colors in Alaska from the comfort of your own car.

If you want to see vibrant reds, oranges, and yellows across a vast tundra landscape, drive to through Denali National Park. Usually, the Denali Road Lottery takes place during the second weekend after Labor Day. However, it’s suspended for the foreseeable future due to the Pretty Rocks Landslide. If you want to see yellow and orange trees, take a scenic fall drive to Hatcher Pass , drive along the Turnagain Arm , or head to Eklutna Lake .

Bear Viewing in Katmai

September is one of the best times of the year to see bears in Katmai National Park. The salmon run is in full swing in September, and the bears are out in force, gorging themselves on fish before they hibernate for the winter.

At Brooks Falls , you can watch bears of all sizes fishing for salmon. Being later in the season, the bears are much fatter now. This is a great time to see the chonky Katmai bears up close, just before they face off for the prize of fattest bear during Fat Bear Week.

Chasing Waterfalls

I love chasing waterfalls! September is a great time to visit waterfalls around Alaska. During the rainy season, the waterfalls can appear fuller. Plus, to get to most of the waterfall hikes near you, it will require a walk through the woods, which means the trees will help to intercept the rain and keep you much drier.

If you’re traveling to Southcentral Alaska, I recommend these easy waterfall hikes near Anchorage.

September Cruise

September is the final month of the cruise season in Alaska as most cruise ships finish touring by the third week of the month. Taking a cruise during the shoulder season is a great way for budget travelers to save money on an Alaska vacation. During your September cruise in Alaska, you’ll have plenty of opportunities to see wildlife, and some incredible scenery. But, you may also just see rain and fog.

For those interested in day cruises, you’ll want to head to Whittier or Seward. In Whittier, you can book the 26 Glacier Cruise to see a ton of glaciers! If you are more interested in seeing wildlife, especially whales, go on a Kenai Fjords Tour out of Seward.

Northern Lights

Seeing the Northern Lights is a bucket list item for many travelers. Alaska is a great place to see the lights as the aurora season runs from late August to April ! This means is actually gets dark enough to see the northern lights in Alaska in September.

However, September is still early in the season and your chances to see the northern lights are much lower than later in the year. If you specifically want to see the northern lights, I would recommend visiting Alaska in February or March. But, if you already have a trip planned for September, don’t worry! You might get lucky and see the lights!

Hut to Hut Hiking

There’s nothing like sleeping in a cozy cabin while knowing you might wake up to frost right outside your doorstep! Alaska has a ton of public use cabins all around the state that you can rent. It’s a great way to experience the Alaska outdoors without having to rough it too much. Think of it as glamping!

One of my favorite hut to hut hiking trails is Resurrection Pass . There are eight public use cabins along the entire trail and you can stay in them as you hike (or bike) from Cooper Landing to Hope. Juneau Lake Cabin and Devil’s Pass Cabin are my favorites along the trail.

Fox Creek Cabin Resurrection Pass Backpacking

Mushroom Photography

Okay.. Over the last few fall seasons in Alaska, I’ve become a fungi freak! I’m basically a mycologist now. With the weather starting to cool down, it’s a great time to head into the forest and look for mushrooms. Alaska has many species of mushrooms , and it’s a lot of fun to see what you can find and photograph.

There are also a couple of mushroom festivals in Alaska in September, where attendees can learn about mushroom identification and cultivation from experts! Find my list of September events in Alaska below.

Top Festivals and Events in Alaska in September

There are plenty of festivals and events to attend in September in Alaska. As a mushroom lover, the Fungus Fair in Girdwood is my favorite September event.

Here are some of the best events in Alaska in September:

Alaska State Fair (August 18-September 4, Palmer)

Labor Day marks the last day of the Alaska State Fair in Palmer. This is Alaska’s largest fair and it’s held annually. You can expect rides, games, vendors and lots of fair food. Some of my favorite things to do at the Alaska State Fair are to watch the Lumberjack Show and check out the giant vegetables. Can you believe the current state record for giant pumpkins is 2,147 pounds?!

Girdwood Fungus Fair (September 2-3, Girdwood)

The Girdwood Fungus Fair is put on by the Turnagain Arm Mycological Society. It’s an annual event that focuses on education and appreciation of Alaska’s fungi and forests. Over the weekend, you can attend talks, workshops, and guided mushrooms walks with mycologists. Last year, I attended a mushroom cultivation workshop to grow oyster mushrooms at home.

Cordova Fungus Fair (September 8-10, Cordova)

Cordova is another city in Alaska that hosts a fungus fair. The Cordova Fungus Festival is a long weekend full of activities to learn more about local mushrooms, participate in art & handcraft workshops, and celebrate mushrooms, salmon, and other wild-harvested foods. There will be live and virtual forays, presentations, activities for kids, and more!

Sacred Acre (September 8-10, Ninilchik)

Electronic music lovers will want to attend Sacred Acre . This EDM festival takes place at the Kenai Peninsula Fairgrounds in Ninilchik. 2023 headliners include, Of The Trees, Boogie T and Daily Bread. On-site camping is available for festival attendees at the ARCHES campground.

Alyeska Climbathon (September 9, Girdwood)

The Alyeska Climbathon is a 10-hour multi-lap, all day event where climbers run and hike up the 2.2-mile North Face Trail (2,000 vertical feet) then descend on the Alyeska Resort Tram to complete a lap. The current vertical record of 26,325 feet and 28.6 miles of running in 13 laps!

Pyrah’s Pioneer Peak Farm Fall Harvest Festival (September 9,16,23,30, Palmer)

Celebrate the fall harvest at Pyrah’s Pioneer Peak Farm in Palmer. This fun, family-friendly event includes, a pick-your-own pumpkin patch, hayrides, barnyard animals, cowtrain rides, a maze, food trucks, and more! Tickets start at $10 per person.

Harvest Moon Local Food Festival (September 16, Soldotna)

Harvest Moon Local Food Festival is the Kenai Peninsula’s biggest one-day farmers market and local food celebration. Held at Soldotna Creek Park, this festival spotlights local Alaskans who grow, harvest and produce all sorts of Alaska Grown and Made in Alaska food and wellness products. It includes vendors, cooking demos, wild edibles walks, a fermentation station, live music and fun activities for kids and families.

Anchorage Pirate Pub Crawl (September 16, Anchorage)

The Anchorage Pirate Pub Crawl has always been a favorite night out with my friends! Everyone dresses up in their best pirate costumes and walks (or crawls) downtown from pub to pub. Make sure to pick up a map and get a stamp from each participating bar for a chance to win 80,000 Alaska Airline miles.

Áak’w Rock Indigenous Music Festival (September 21-23, Juneau)

Áak’w Rock is a three-day Indigenous music festival, held biennially on the ancestral homelands of the Lingít (People of the Tides) of the Áakʼw Ḵwáan (People of the Little Lake). It is the only Indigenous music festival in the United States, and it showcases Indigenous music of all different genres from around the world.

Ice Fest (September 22-24, Matanuska Glacier)

Ice Fest is an ice climbing event put on by the Mountaineering Club of Alaska. Climbers will learn about modern ice climbing techniques, rope management skills and socialize with other local climbers over the weekend.

Oktoberfest (September 23, Anchorage)

Oktoberfest in Anchorage is back! If you want to celebrate German culture with a full day of dancing, music, food and lots of beer, then this is the event for you! Live music this year will be performed by Alaska Blaskapelle and The Alaska Polka Chips. Prost!

Make it Alaskan Market (September 29-October 1, Anchorage)

The Make It Alaskan Market is held in downtown Anchorage at the Egan Center. Event-goers can shop a huge selection of locally made products, arts & crafts, clothing, housewares and so much more. If you are looking for an Alaska souvenir to take home then this is a great place to visit in September.

Capital Brewfest (September 30, Juneau)

I love a brewfest! The Rotary Club of Juneau is hosting its 11th Capital Brewfest this year. You’ll be able taste some of the best brews, ciders, and meads in the entire state. Some of my favorite Anchorage breweries will be there including, Alaskan Brewing Co., Double Shovel Cider Co., King Street Brewing Co., and, Midnight Sun Brewing Co.

What to Pack For Alaska in September

Some days you can still walk around in shorts and a t-shirt, but with cooler weather and temperatures in Alaska in September, your Alaska packing list will need to include some warm layers!

If you plan on taking a cruise in Alaska in September, you want to make sure to bring a warm hat, a warm jacket and warm gloves.

If you plan to spend time outdoors, whether you’re hiking or camping, make sure to pack good rain gear and warm base layers to wear on your September adventures.

No matter what your plans are, here is a quick list of what to wear in Alaska in September:

Down jacket
Rain jacket
Waterproof hiking boots
Warm gloves
Fleece sweater
Warm base layers

Is it a good time to visit Alaska in September?

If you want to experience Autumn in Alaska then September is the great time to visit Alaska. The fall colors will be popping and it really is beautiful to see! By traveling in September, you will avoid the summer crowds and summer costs. However, if you visit in late September, you won’t be able to enjoy all of the tours that are available in the summer as the tour operators close for the season.

I hope this guide on visiting Alaska in September was helpful as you plan your trip to Alaska! Do you have any questions about visiting Alaska in September? Let me know in the comments.

Hi, Great blog ! I read somewhere that autumn equinox is a great time to see northern lights which is around mid september. Do you know if this is correct ? Also is 2024 year the best to view northern lights ?

You can see the Northern Lights in Alaska as early as September because the skies are finally getting dark enough. Last year there was definitely a lot of early season aurora activity, but every year is different.

Alaska Cruise Tips: When to Go, What to Pack, How to Choose, and More

I’m a seasoned traveler who firmly believes the best way to experience Alaska’s incredible scenery is on an Alaska cruise.
Think of an Alaska cruise like a floating hotel that carries you to a breathtaking new destination each day.
Whether you’re a first-time cruiser or have lots of shipboard experience, these tips will help you make most of your Alaska cruise vacation.

I’ve cruised all over the world, and I can honestly say there’s no other cruise experience that quite compares to an Alaska cruise. Seeing the untouched landscapes, glacier-dotted shorelines, and penguins and bears at play really puts life into perspective—and makes for a truly unforgettable travel experience no matter your age.

Many people choose to make an Alaska cruise their first foray into cruising . First timers are attracted to the state’s majestic beauty, but not necessarily savvy to the bounty that a cruise ship offers. If you’re considering a cruise to America’s Last Frontier, here’s how to make the most of it.

EVERYTHING’S INCLUDED: 7 Best All-Inclusive Cruise Lines in the World

1. You can Save Money by Cruising to Alaska in May, June, and September

The Alaska cruise season is brief. Alaska cruises start each year in May and run through early October. The most popular (and expensive) months to cruise are July and August, coinciding with summer family vacations and translating into ships that are often filled with kids.

If you aren’t tethered to a school-year schedule ( or don’t mind taking your kids out of school ), you may want to consider a shoulder season cruise to Alaska. This translates to sailings in late May, June, or September. On these shoulder season cruises, you’re likely to find lower prices and less crowded cruise ships.

2. Pack for All Four Seasons (and Don’t Forget Binoculars)

Alaska’s climate is notoriously unpredictable. I advise packing warm clothes that are easy to layer on and peel off. Bringing gloves, hats, and a scarf is not unreasonable. On the flip side, Alaska is quite far north, and long summer days offer midnight sun and potentially warm temperatures. Many ships have swimming pools and hot tubs, so don’t forget bathing suits and sunscreen .

A comfortable pair of walking shoes are a must if you want to keep your feet feeling good as you explore each port of call. Binoculars can help you spot a range of animals in their natural habitat. Make sure each person in your group has their own pair so they can spot Alaska’s Big Five land mammals (Black and brown bears, moose, wolves, caribou, and Dall sheep) as well as orcas, puffins, and bald eagles.

3. Shore Excursions Are a Must

As wonderful as shipboard life is, to really experience Alaska you need to disembark at each port of call. Getting off the ship is a great way to get in touch with native Alaskan culture that’s reflected in towering totem poles, hand-woven decorative fabrics, and other native crafts. Alaska cruises offer dozens of shore excursions from whale-watching to dogsledding, many curated with kids and families in mind.

4. How to Choose between The Inside Passage or the Gulf of Alaska

The sheltered waterway known as the Inside Passage is a very popular cruise route. As your ship weaves through a patchwork of islands, with fjords and glaciers thrown in for good measure, you’ll witness wildlife and scenery that looks lifted from a postcard. Alaska cruises taking this route usually make a round-trip journey from either Seattle or Vancouver, cities that have major airports with numerous flight options.

The other popular cruise itinerary is the Gulf of Alaska, a stretch of the Pacific Ocean that hugs the southern coast. This equally scenic itinerary is usually a one-way sailing, departing from Seattle or Vancouver and terminating in either Whittier or Seward, Alaska (or vice versa). If you want to add on post- or pre-cruise destinations such as Anchorage and Denali National Park, starting or ending your cruise in Alaska makes it easy to do so.

Keep in mind you will arrive and depart from different cities, requiring the purchase of a multi-city airline ticket (unless you live within driving distance from Seattle or Vancouver), which can be quite costly.

5. Utilize the Onboard Naturalist

Booking an Alaska cruise cruise that has an onboard naturalist is a no-brainer. On my recent Princess cruise to Alaska, our Canadian naturalist went above and beyond his job’s description, spending each evening on deck 16 hanging out with passengers, helping us spot humpback whales and see the Northern Lights until well past midnight.

Small ship cruise lines such as Lindblad Expeditions, which partners with National Geographic , offer families a deep dive into the natural world with the expertise of naturalists who cater to curious kids as they learn environmental stewardship.

If your ship takes you to Glacier Bay National Park, park rangers are usually brought on board as the ship cruises through the park, helping you to better understand the fragile beauty surrounding you.

6. Spring for an Exterior Stateroom

While interior cabins will save you money, Alaska’s eye-candy beauty and abundance of wildlife merit the added expense of an exterior stateroom (with a balcony if available). From the moment you wake up, you’ll be treated to spellbinding scenery at all hours.

7. Don’t Skip the Buffet

While many large and mid-size cruise ships promote their specialty restaurants, these dining options usually incur an extra fee, which can quickly add up when you’re booking a table for your entire family. The ship’s buffet is a low-stakes, no-additional-cost way for kids to sample global cuisine. If crowds are a deterrent, hit the buffet a bit early or late, when lines tend to be thinner.

On my family’s recent Alaska cruise, we were thrilled with the smorgasbord of edible delights from across the world. We couldn’t get enough of the authentic Indian food, feasting on tandoori chicken and fragrant curries served with refreshing raitas and savory chutneys. The Chinese food section let us customize our stir-fry with veggies and proteins of our choice, including tofu, perfect for my vegetarian daughter.

8. Be Prepared for Some Seasickness

The Inside Passage is sheltered, equaling waters that are usually quite calm. However, if your itinerary crosses the Gulf of Alaska, the sea tends to be rougher. Whichever route your ship takes, being prepared with seasickness remedies is essential. I don’t suffer from sea sickness but my daughter uses Sea-Band acupressure wristbands with good results.

9. Take Advantage of Onboard Activities

Most large and mid-size cruise ships sailing Alaska itineraries have age-appropriate supervised clubs for kids and teens at no additional cost. These programs give young passengers the opportunity to spend time with their peers and try new activities, freeing parents to enjoy a bit of adult time.

BRING THE KIDS: 7 Great Cruise Lines for Families (and Their 12 Most Kid-Friendly Ships)

Cruise ships offer a range of ways for families to spend time together. Try a game of pickleball on all Holland America ships or enjoy a ride on the bumper cars at Royal Caribbean’s SeaPlex, the largest indoor activity complex at sea. Evening entertainment, including Broadway-style musical performances on Disney cruises, is always a highlight as well.

10. Discounts for Kids Are Real and Significant

Keep an eye out for periodic kids sail free deals where children ages 18 and under can sail for no charge beyond taxes, fees, and port expenses. These promotions make a family vacation more affordable. Holland America is one cruise line that offers these bargains frequently on Alaska cruises, while small ships such as Lindblad and UnCruise always offer a $500 discount for children.

The remarkable scenery of Glacier Bay is a highlight on many Alaskan cruise itineraries.

Embark on a journey through Alaska's pristine wilderness aboard a cruise ship, where you can experience the awe-inspiring nature of the last American frontier in comfort.

As you glide past icy fjords and into secluded bays, seize the chance to witness magnificent glaciers up close, and keep your eyes peeled for the mighty bears, whales and eagles that call this rugged landscape home.

However, don't make the mistake of thinking you’ll have peace and quiet. Remote it may be, but Alaska is one of the world’s most popular cruise destinations.

Ports such as Skagway can accommodate up to four large cruise ships at once. Smaller ports can easily become overwhelmed with visitors, while popular shore excursions sell out well in advance. As such, there’s a lot to understand about Alaska cruises before booking.

Cruise Lines In Alaska

Most major cruise lines sail in Alaska, ranging from large, modern ships full of amenities, down to smaller, older ships with more outside space and a relaxed vibe. Expedition cruises on even smaller ships focus more on wildlife and geology.

When picking a line and ship, consider your choice of cabin carefully. Although inside cabins offer a cheaper deal, the value of a balcony cabin shouldn't be underestimated. On scenic cruising days, you’ll be able to enjoy the landscape—and potentially wildlife—without jostling for position.

Alaska Cruise Itineraries Explained

There are two main types of Alaskan cruise itinerary: the Inside Passage roundtrip, and a one-way Gulf voyage. Each route offers unique opportunities to see both glaciers and wildlife, with specifics depending on the season.

Alaska is a popular cruise destination in the summer.

Seven-night Inside Passage cruises typically depart from hubs like Seattle or Vancouver, calling at popular stops like Juneau, Ketchikan, and Skagway. Many feature a scenic cruising tour of the breathtaking Glacier Bay National Park.

For example, this 7-night itinerary on Norwegian Encore including all those highlights is available between April and October in both 2024 and 2025.

For those seeking deeper exploration, one-way Gulf voyages include the highlights of the Inside Passage route, but also venture closer to the Arctic Circle. Typically, such itineraries start or end at Whittier or Seward near Anchorage.

This 7-night itinerary from Celebrity Cruises includes port calls at Sitka, the historic Icy Strait Point, and scenic cruising of the Hubbard Glacier on the way from Vancouver to Seward.

Some cruise lines combine Gulf voyages with curated tours before or after the cruise for a comprehensive Alaska experience. Such tour packages include famous rail journeys, visits to Denali National Park, and optional overnight stays in Anchorage or Fairbanks.

Longer Alaskan cruise itineraries, especially those on smaller ships or expedition lines, may include remote locales like Kodiak Island and the Aleutian Islands.

Port Excursions In Alaska

Exploring ashore on guided excursions is a highlight of any Alaskan cruise. Each port offers unique opportunities to engage with the natural environment and local culture, but the popularity of cruising in the region means advance booking is essential.

Some of the most popular tours may fill up just days after they go on sale, in some cases months before the actual cruise. Consider independent tour options, but read the terms and conditions carefully and check for reviews from previous cruisers.

Mendenhall Glacier is a popular cruise excursion from Juneau on Alaska cruises.

Alaskan capital Juneau is renowned for its glacier tours and wildlife viewing opportunities. The hike through backcountry to the Mendenhall glacier requires a good level of physical fitness, while whale watching boat trips are just as popular.

The historic Skagway train tour along the Klondike route in a vintage coach, featuring stunning vistas and rich gold rush era history, is a must-do.

Cultural tours in Ketchikan often include visits to the Saxman Native Village, where totem poles and traditional dance performances offer insight into the local Tlingit culture.

When To Cruise Alaska

Alaska is not a year-round cruising spot, and the season is shorter than most leading cruise destinations. Alaska’s cruising season ranges from late April to late September.

April : Expect relatively dry days, though not completely devoid of light showers and fog. Bears are only just emerging from their winter slumber so sightings are unlikely, but you may see eagles and humpback whales.

May : With more ship options, relatively dry weather, long hours of daylight, and good value fares, May is a popular time to cruise Alaska before the peak. Wildlife, including migrating shorebirds, whales, and bears, are more visible.

June : Mild temperatures and long daylight hours—up to 19 per day—provide optimal cruising conditions. Enjoy vibrant greenery and more wildlife sightings, but prepare for the possibility of mosquitoes (especially on trips inland) and variable weather.

July : July brings mild temperatures, often reaching the 70s, but it's also the start of the wetter period. Expect long hours of daylight ideal for wildlife sightings, including salmon runs and bear activity. However, peak cruise season means high fares, busier ships, and busier ports. Local produce starts to feature heavily on menus shoreside.

Juneau, Alaska, has a spectacular natural setting and is a gateway to many exciting outdoor ... [+] experiences.

August : Expect rain, with daytime temperatures in the low to mid-60s and nights cooling to the upper 40s, and ample wildlife viewing opportunities, as bears and bald eagles are active near salmon streams. Fares, along with the number of daylight hours, fall later in the month.

September : Expect cooler temperatures and frequent rain, which may risk the success of outdoor excursions. Despite less demand, wildlife viewing remains good with bears still active near salmon streams and whales still present in coastal waters. September also offers a chance to see the northern lights .

What To Pack For Alaska Cruises

Packing smart for an Alaska cruise means being prepared for both adventure in the great outdoors and the comforts of cruise life.

An Alaskan journey demands attire for cooler climates. Essentials include a fleece jacket, thermal socks, and a warm hat to combat the cold, along with sweaters and thermal underwear for effective layering. Waterproof gear such as a reliable rain jacket and waterproof pants are crucial for unexpected rain or snow showers.

You should also consider waterproof bags to protect your electronics and important documents during shore excursions.

Sun protection is vital due to the deceptive Alaskan sun. High SPF sunscreen, sunglasses, and a wide-brimmed hat are necessary to guard against UV rays and snow glare.

Footwear should include waterproof hiking boots for rugged terrain and slip-proof sandals for the deck, accompanied by thermal or wool socks for additional warmth.

For shore excursions, a collapsible backpack and a thermal water bottle will keep you organized and hydrated, while binoculars can greatly enhance wildlife tours. A simple first aid kit, sea-sickness bands, and insect repellent are other wise packing choices.

Royal Caribbean cruise cancels voyage to Alaska after the guests already boarded

A Royal Caribbean cruise to Alaska was scrapped after guests had already boarded the ship.

The ship, “Radiance of the Seas,” had been experiencing some propulsion issues , causing the cruise liner to shorten and eventually cancel the weeklong itinerary through Alaska.

The cruise was initially planned to set sail from Vancouver, but the cruise liner announced it would remain in port for two days before setting sail. But then, the captain announced Saturday afternoon that guests would need to disembark the ship by Sunday at 4 p.m.

“Due to a technical issue, we have made the difficult decision to cancel the April 26 sailing,” a Royal Caribbean spokesperson said in an emailed statement . “Guests will receive a full refund and 100% future cruise credit, and have been notified directly.”

Guests on board the cruise had mixed reactions.

“While I’m still very sad I didn’t get to see Alaska this year, I believe I’ll have another opportunity to go, and this cancellation provided an additional opportunity to get to know Vancouver, which is truly a very cool city,” one passenger wrote on the Royal Caribbean blog.

Another passenger, however, said she doesn’t think she’ll use Royal Caribbean the next time she goes to Alaska.

“I would like to go to Alaska,” passenger Charlene Chong told USA Today. “I’m not sure if I want to go with them.”

This isn’t the first time a Royal Caribbean cruise has had to change its itinerary recently.

The cruise liner stopped ships from docking at a private island port in Haiti due to ongoing violence in the region.

This decision by Royal Caribbean to change the itinerary on that cruise came after the U.S. issued a warning to tourists to avoid traveling to Haiti at this time due to an increase in gang-related violence.
