Our verdict

The best time to visit Alaska is May-September

Alaska is a place lots of people visit almost all year round, but if you’re looking for the best time to go, May-September is definitely the time you should visit. This is based on a number of factors such as the weather, cost of flights and accommodation, peak travel periods and more.

In summer, the daytime temperatures in central Anchorage, Alaska can reach a top of 18℃ (65℉). The temperature at night in the winter can drop to as low as -21℃ (-6℉), although this can differ at other destinations across Alaska depending on the geography.

The days are longest in Alaska in May, so if you want to see the sights during the day when the sun is up for the longest time, it’s best to visit around that time of year. To stay dry, avoid travelling to Alaska in September – It’s the wettest month of the year.
