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

Every month in Alaska has something incredible to offer, and Alaska in August is no exception!

August is the last month of the summer season in Alaska, but that doesn’t mean the fun has to end. With warm-ish weather and long days, there are still plenty of things to see and do.

As someone who lives in Alaska, I call tell you that a vacation in Alaska in August can be ideal if you want to avoid the crowds seen during peak season, but avoid the cold weather months.

If you’re considering an August 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 August.

5 Reasons to Visit Alaska in August

  1. The weather is mild and sunny. The average temperature in August is in the mid-60s, with plenty of sunshine.
  2. The wildlife is abundant. August is a great time to see some of Alaska’s most iconic wildlife, such as bears, moose, whales, and salmon.
  3. The days are long. In some areas of Alaska, the sun doesn’t set until after 10 p.m. in August, so you’ll have all day to enjoy your favorite vacation activities.
  4. The crowds are smaller. August is a popular time to visit Alaska, but it’s not as crowded as June and July. This means it’ll be slightly easier to book activities and accommodations, especially in the second half of the month.
  5. Less bugs! Colder weather in August means you won’t see as many mosquitoes and other bugs.

Aurora Viewing in Alaska in August

Darker nights increase the possibility to see the aurora borealis. Aurora Season begins on August 21 and your best chance of seeing the northern lights in Alaska in August is in the Fairbanks region. Seeing the aurora this early is never a guarantee. The only time I’ve seen the northern lights in August was on an overnight backpacking trip on Crow pass near Girdwood. And yes, it was incredible!

Rain in Alaska

So, does it rain a lot in Alaska in August? August is actually one of the rainiest months of the year in Southcentral Alaska. Anchorage has an average of 10 to 15 days of rain during August. Southeast Alaska is still considered a drier month even though Juneau has an average of 17 days of rain during August.

August days stretch into the evening as the sun doesn’t set until well after 8 p.m. in most cities around the state. With all of this daylight, you can still enjoy all of the same June and July activities during August.

Soak up the last bit of summer with these fun things to do in Alaska in August:

Salmon and Halibut Fishing

August is a great time to fish for coho or silver salmon and halibut. If you’re in Anchorage, you can actually fish for salmon downtown in Ship Creek. If you head south, the Kenai River and Russian River are also great fishing spots for salmon. August is also a great month to book a salmon charter in Juneau.

If you want to fish for halibut, head to Whittier or Seward. Book a trip with a charter service or guide that can take you out into the deep waters.

Visit Denali National Park

One of the top attractions in Alaska during August is Denali National Park. Most visitors are looking to join the 30% club of those who actually see Mount Denali, the tallest peak in North America.

Denali is also a top choice for wildlife viewing opportunities in August. This national park is home to the “Big 5” wildlife, which includes bears, wolves, caribou, moose and Dall sheep.

You can visit the park for free on August 4 in celebration of the Great American Outdoors Act. This is one of the five free admission days for all National Park Service sites.

Go Whale Watching

August is a great month to see whales in Alaska, especially if you want to see humpback whales and beluga whales. Take a boat tour in coastal areas like Kenai Fjords National Park and Juneau and look for humpback whales bubble net feeding.

For beluga whales, drive along the Turnagain Arm. As the whales follow the salmon and hooligan runs, you can spot them just off the highway. I usually spot the first beluga whales of the season from mid to late August.

Plan a Hike

Hiking is one of the best outdoor activities in Alaska in August. Whether you want to go for a day hike or plan a multi-day backpacking trip, the extended daylight in August makes it a great time to go.

There are so many incredible trail to explore around the state. You can walk on Root Glacier in Wrangell St. Elias, climb Mount Roberts in Juneau, or hike hut to hut along Resurrection Pass. You’ll find that some routes are better to plan in August as lingering snow continues to melt up in high passes.

As the month goes on, you’ll most likely see the summer foliage be sprinkled with signs of fall. The fall season is quick but it’s so beautiful to hike through the mountains surrounded by fall colors.

Get On the Water

During the rainy days in August, I still like to get outside. When it’s raining, I feel like it’s much easier to choose water activities over hiking. There are lots of places around Alaska to paddle, whether you prefer to kayak, canoe, SUP, or packraft.

August is actually a great time to paddle in areas that usually have a ton of mosquitoes, like Swan Lake Canoe Trail in the Kenai National Wildlife Refuge. If you are an experienced paddler, visit Eklutna Lake or Portage Lake in Southcentral Alaska.

Wild Foraging

During mid to late August, you’ll come across lots of edible wild plants, mushrooms, and berries in different parts of Alaska. One of my favorite things to forage for in Alaska are berries. You can find salmonberries and cloudberries, but I love picking wild blueberries and turning them into blueberry scones! I usually find blueberries in Hatcher Pass, Arctic Valley, and Whittier.

In the last few years, I’ve started to harvest a bit more than just berries. I picked fireweed flowers from a huge field to make fireweed jelly and I finally found some hedgehog mushrooms! I’ve enjoyed learning about mycology and trying to identify and cook as many wild mushrooms in Alaska as possible.

Cruise in Alaska

August in a popular month to cruise in Alaska. Generally, most travelers choose to book a cruise during August because it’s usually cheaper. There are plenty of week-long cruise options that depart from Vancouver and take you through Alaska’s Inside Passage.

During your August cruise in Alaska, you’ll have plenty of opportunities to see wildlife, like bears, and whales. For bird watchers, August is a great time to see migratory birds along the coast. You’ll also be able to see some incredible scenery, like glaciers, waterfalls, and rainforests.
