Traveling to Alaska during July and August enlightens all the senses by offering vibrant colors, sounds, smells, and tastes of an amazingly wondrous state. It is the only time that all that the state has to offer is open and full of energy.
Compared to winter, more animals are on the move, roads and trails are free of snow so easier to traverse, and excursions of every kind are beckoning to all tourists. The summer months are also the busiest so taking the time to research areas less traveled will help to not get caught up in heavy crowds.
If you plan to visit the Last Frontier in July and August, be ready to be immersed in the ultimate Alaska experience with our guide below. We cover everything in detail: Weather, what to wear, crowds, how to get around, driving, mosquito tips, things to do, wildlife, and more.
This article was written by our Alaska residents, who have lived there for years and have visited almost every region in Alaska at various times.
The climate in July and August varies across the three main regions of the state: Arctic, Interior, and Coastal. The amount of daylight differs along with the average daily temperatures, with the northern region having the longest days and coolest climate.
July has the warmest temperatures of the year in Alaska. The average highs range from 61°F (16°C) to 73°F (23°C) in the interior and coastal regions. The days are long with over 19 hours of daylight in many regions. July is also one of the driest months with a 27% chance of rain on average. All trails and roads are accessible and snow-free.
Alaska is mostly mild and warm in August with average high temperatures from 60°F (15°C) to 67°F (20°C) in the most-visited areas. Temperatures are dropping 5-10°F towards the end of the month. The average rainfall is between 1.8 and 3.1 inches in Anchorage and 6.8 to 10.9 inches in Juneau. It doesn’t snow in August.
We always wear waterproof, breathable rain gear during the summer months in Alaska, as you may hit rain anytime. Read more details about rain and what to wear below.

What to Wear | What to Pack
Layering is essential, even in the summer months. The weather can change fast at any time, and the conditions vary across Alaska. At higher elevations and during morning and evening hours, it will be chillier.
Also, keep in mind that extreme windy locations (see our list at the end of the article) have an effect on the perceived temperature. All of these areas and the different times of the day require layering.
During Alaska’s summer in July and August, you should wear moisture-wicking fabrics such as nylon and spandex. They are great for this climate and are easy to layer.
For cooler summer days or mornings, wool/fleece sweaters and socks keep you warm and work well in layering. For sunny days pack shorts and short-sleeved shirts.
Waterproof clothing as the top layer is an important factor when being exposed to Alaska’s unpredictable weather.
Our pants tips:
Shoes: Insulated, durable waterproof/resistant shoes/boots with good sole traction will provide travelers with a cozy and dry experience during any excursion. Some boot suggestions are Baffin or BOGS brands (check prices on Amazon.com). They have numerous designs and are perfect for Alaska’s environment.
Jacket: A fleece or nylon blend jacket with a hood or any waterproof/resistant jacket should be your outer (shell) layer. Even if your jacket has a hood, bringing a toboggan, scarf and waterproof/resistant gloves are essential. Our jacket tips on Amazon:
How many jackets? Depending on the length of your trip, we recommend bringing two (or even three) light jackets for your Alaska summer adventure.
Shorts/Sandals: For July and August, we always add shorts and summer shirts made of moisture-wicking materials as well as closed-toed sandals with durable, good traction soles. If it does get hot, wearing lighter-colored clothing absorbs less heat. That allows you to stay cooler and also helps to repel mosquitoes.
- Nylon/Spandex shirts, shorts, pants/leggings – skin layer or top layer
- Wool/Fleece Sweaters – mid-layer
- Waterproof/Resistant pants – outer layer
- Waterproof/Resistant coat with hood
- Waterproof ball cap
- Waterproof/resistant gloves
- Merino wool socks or any warm moisture-wicking socks
- Waterproof/Resistant shoes closed-toed sandals, and or boots
*Cotton clothing is not preferable due to its ability to absorb moisture
- Travel First Aid Kit
- Paracord Bracelet – If going to remote areas
- Bug Spray
- Mosquito netting for your head
- Windproof umbrella
- Eye mask
- Portable charger
- Chapstick – Alaska’s climate is dry
- Lotion, moisturizing shampoo and conditioner
- Reusable Water Bottle – Tap water is ok to drink
- Binoculars (some tours may provide them as well)
- Cash – In some areas, vendors may not take credit/debit cards or digital payments
- Hand and Toe warmers for colder days
Crowds | How Busy Is It?
July/August are the busiest months for traveling in Alaska. The weather is at its best, and all activities are in play. Many popular tours and excursions will be busy and crowded. Cruise ships are docking daily at the ports, and tours of every kind are running at their maximum.
Crowded places: Some of the busiest areas such as Anchorage, Fairbanks, Denali, Juneau, Talkeetna, Girdwood, and Seward-Kenai Peninsula will be booming with tourists.
Most traveled roads: The majority of visitors travel south from Anchorage on the Seward and Sterling highways to places on the Kenai Peninsula destination or north up the Parks Highway to Denali National Park and Fairbanks.
Our 5 top tips to avoid the crowds
- If you are visiting cruise towns you can avoid the crowds by traveling further inland to see the area. Most cruise passengers stay in close vicinity to the dock (2-3 blocks radius).
- To miss the crowds in typical tourist areas, you can take the ferry on the Alaska Marine Highway System. This ferry takes you to less frequented parts of Alaska’s inside passage, for example, Wrangell (The downside: It can take between 3-6 hours to go from port to port).
- Visit Alaska areas that are less known such as Kodiak Island (must take a flight there) or Wrangell-St. Elias National Park and Preserve. Book a remote outback hunting or fishing expedition or even a guided hike and stay in a secluded B&B or wilderness lodge. Finally, take a road trip on the Glenn Highway into the Copper River Basin or Richardson Highway between Valdez and Fairbanks.
- You can avoid crowds via charter flight to Whittier, Seward, and Haines. They offer drop-offs to remote beaches and islands. You can spend a day beachcombing or even a full week camping and fishing.
- To avoid fishing crowds, contact the Alaska Department of Fish and Game, adfg.alaska.gov/sf/Fishing, to find out during your trip where the fishing won’t be so heavily populated. Areas that draw a lot of fishing crowds are Russian River, Ship Creek, Seward Beaches, and Homer Lagoon.
With the amount of daylight in July and August, it is not a good time to view the Northern Lights in Alaska. This beautiful phenomenon is most easily seen from September – to April.

Booking in Advance
It’s peak season! July and August are both the busiest month in Alaska. Book well in advance. Some tours can be booked on short notice, but we always recommend making reservations in advance for hotels and tour activities.
- Anchorage (via booking.com): Sort by star rating & price
- Talkeetna – Hotel Deals: We recommend staying one night in Talkeetna when driving from Anchorage to Denali
- Denali National Park (we recommend Healy instead of the touristy Glitter Gulch)
- Fairbanks (via booking.com): Sort by star rating & price
- Seward (via booking.com): Sort by star rating & price
Tip: Bookmark the links if you want to browse for the best prices later.
- Peak season: Late June, July, and early August
- Time of day: At dawn or dusk (peak time)
Summer is mosquito season, in particular throughout July and in early August.
Worse areas: If traveling north of the Arctic Circle, there will be a heavy mosquito presence. You will encounter a larger mosquito presence in heavily wooded areas, near streams or lakes. Denali National Park is known for its larger mosquito populations.
Better areas: These little critters aren’t as bad in the urban areas, especially in major cities like Anchorage and Juneau. Also, you won’t encounter many of them along the coast due to the constant breeze.
Tips to avoid getting bitten: Carry bug spray. Most experts recommend DEET. Additionally, wearing light-colored clothing will help to repel the mosquitoes. You can keep the mosquitoes from your head with a waterproof ball cap along with a mosquito head net over it. Additionally, avoid anything that is scented, like scented lotions or shampoo.
Warmer weather and longer days make July and August prime time for Alaskan excursions. Being able to book activities as late as 10 pm, provides tourists with an enormous amount of time to enjoy this beautiful state.

Flightseeing | Day Cruise | Arctic Circle
Alaska is a wonderful and magical place to experience in July and August. The state is so large one could travel the whole summer and not see the entire state. We recommend at least one of these three intriguing experiences below. You will be touched by the magical spirit only Alaska can offer in July and August:
- Talkeetna (between Anchorage and Denali): On a jaw-dropping plane flight you will experience glaciers, massive mountains, and the majesty of Denali itself. Visit Talkeetna when driving from Anchorage to Denali. Reservations: Talkeetna: Mountain Voyager with Optional Glacier Landing

- Fairbanks: On this unique tour with excellent and super-friendly guides, you visit the spectacular Arctic Circle and walk through the breathtaking landscapes around Yukon River. Reservations here: Arctic Circle Adventure – Full-Day Tour
The Kenai Fjords National Park Cruise (see above) is amazing for whale watching and the summer months are the peak time for many species.
If you are in Juneau as well, we highly recommend this Whale Watching Adventure. You will be able to spot humpbacks, killer whales, and other fascinating species in July and August.
Tip: Always make whale watching reservations in advance as these tours are likely to sell out!
- Car: Throughout July and August
- Motorcoach (Bus): Every day in July and August
- Train: Every day in July and August
Once you arrive in Anchorage or in Seward, the best ways to travel in Alaska during the summer months are by car, train, or motorcoach/bus. A great idea is to combine train and motorcoach if you are using a rental car. By taking the train on at least one route, you are able to view mesmerizing landscapes that can only be seen on the railroad.
Tip: Most locals say, that the most scenic landscape via train is the train route from Anchorage to Seward. The views are truly unique on this 4-hour ride.
In July and August you have access to all three modes of transportation:
- Car: Renting a car is the best way if you want maximum flexibility. Since all roads are clear of snow and accessible in the summer, you can drive to most places easily. Make your reservation for a rental car in Anchorage well in advance.
- Motorcoach: The Alaskan Park Connection Motorcoach is a very convenient way to get to and from Anchorage, Denali Park, Seward, Talkeetna, and Whittier. There are two daily departures from Anchorage to both Seward and Denali National Park. Make sure to check the current schedule: Official Alaska Coach Park Connection Schedule
- Train: Experience Alaska by train is more expensive than the motorcoach, but a truly unique adventure. Trains are available to all major destinations: Anchorage, Talkeetna, Denali Park, Fairbanks, Whittier, and Seward. Check the official schedule here: Official Alaska Railroad Schedule
Tip: If you visit Alaska via cruise ship and arrive in Seward or Whittier, you can make use of the many transfer options offered by Alaska Train & Motorcoach.

Driving and Roads
Driving around the state of Alaska can be mind-blowing. The absolute beauty it offers can render someone into a state of awe but planning ahead is key in being able to experience a wonderful as well as safe trip.
July and August have the best and safest road conditions but driving on your own through Alaska should be done with caution. Even with snowmelt happening a few months earlier, travelers need to always be aware of constantly changing weather and road conditions.
Unmaintained highways over the winter:
- Denali Park Road: Open year-round but only maintained to park headquarters at mile 3.4 and the road is open to the public from late April until the shuttle buses start running in mid-May. Check the park website for road conditions: nps.gov/dena/planyourvisit/conditions.htm – Only the first 15 miles paved
- Denali Highway: Typically reopens by May 15 – Partially paved

When renting vehicles, rental car companies may require renters to sign compliance forms agreeing not to drive off paved roads. The choice of the rental depends on where you want to travel to.
If renting a car, inquire at the rental agency as to which vehicle is best for the area you are driving. Off-road and higher elevations need vehicles like a Jeep Wrangler, Toyota Tacoma or 4 Runner. Having the proper items with you during a road trip in Alaska is essential. Important items needed are shown below:
- All-weather or Studded tires for snow-covered roads
- Test car battery
- Change the oil
- Clean battery terminals
- Lubricate door locks, door hinges, and window weather stripping
- Check tire tread and air pressure
Essential Items to store in your vehicle:
