When is the best time to visit Alaska?

Due to the northerly latitude, the main travelling season in Alaska is limited to the summer months of mid-June to mid-September. Alaska’s wildlife, including bears, sea otters, seals and whales, is visible throughout this period, although June and July tend to be the best months for sightings. The warm weather and long days make this a particularly pleasant time of year. The weather in Alaska changes very quickly at any time of year, but many excursions stop operating in early September in anticipation of the wintry weather. Unless you are looking for winter sports or northern lights in extreme conditions, the winter months are best avoided.

Our favourite time of year is July, which is really the best time of year to visit. The days are long with plenty of daylight and can be warm and sunny. The Alaskan wildlife has emerged from winter hibernation and national parks are open and accessible, with walking trails offering spectacular views. Communities across the state celebrate the summer and there are a number of cultural events and local festivals to enjoy.

Month-by-month guide to travelling in Alaska

The Alaska Range, Denali National Park

Visiting Alaska in January - April

Alaska’s long winter stretches from October through to April, during which temperatures plunge to well below freezing, the nights are long and much of the state goes into a hibernation-like shutdown. Although winter sports are available and a few lodges offer northern lights viewing, this is not the best time of year to visit Alaska.
