Also during the summer?

YES. It’s not uncommon to be traipsing down a trail on a lovely June morning, wearing shorts and a T-shirt, and only a few hours later find yourself caught in a storm, having to don an army’s worth of warm clothes and raingear.

The key to dealing with the weather in Alaska is to dress in layers. Fronts come in and fronts go out, day after day. So, be prepared to meet the weather regardless of temperature or moisture!

What does an Alaska weather summary look like?

Something like this ...

The Alaskan weather has a historical tendency to be more drier and calmer in the spring and early summer throughout most of the state, deteriorating through late summer and fall, although it can vary dramatically from year to year.

Many people consider the period between May and early September to be the best time to visit Alaska. And within that period, late May through June usually has the best combination of long days, clear skies and warm afternoons.

And ... If you’re planning an Arctic or Northwest trip, keep in mind that the season is effectively over by early September in most years.

Alaska is a big state and weather can vary greatly by region and season. Southeast Alaska typically receives the most rainfall, while warmer sunny weather is typical of interior Alaska summers.
