Northern Lights Viewing in Alaska

The northern lights, also known as aurora borealis, occur about 60 or 70 miles above the earth’s surface — about 10 times higher than a jet aircraft flies — and can extend hundreds of miles into space. Electrically charged particles traveling through the earth’s magnetosphere collide with gasses, creating energy in the form of light. 

The intensity of solar flares varies the intensity and extent of activity within the Auroral oval, the ring-like area above the geomagnetic north where auroral activity is concentrated. The most common color displayed is a brilliant green, but the aurora borealis can also produce red and purple patterns. 

The best time to see the northern lights in Alaska is between late-August and late-April, when less daylight leads to darker night skies. While the aurora can be see any time the sky is dark, they are most often seen between 10:00pm and 2:00am. 

The northern lights can be seen anywhere in the state but are most often seen in the Interior and Arctic regions, which offer clear, dark skies away from city lights. The Southcentral region is another good basecamp for northern lights viewing. Fairbanks is one of the best places to view the northern lights in Alaska due to hours of darkness in winter, auroral activity, and the amount of tours, activities, and accommodations dedicated to northern lights viewing. Other interior and Arctic regions offer more remote northern lights viewing opportunities including the Denali area, Coldfoot, and Wiseman. In the Southcentral region, top destinations include Anchorage, Girdwood, and the Mat-Su Valley. 

To increase your chances of seeing the aurora borealis, join a guided northern lights tour, which are available in the Interior, Arctic, and Southcentral regions. Tour guides know the best spots for viewing and can take you off the beaten track to remote viewing locations with less ambient light. They offer single day tour options, or you can increase your chances of viewing with multi-day overnight northern lights packages, which often include meals and overnight stays at unique, remote lodging specifically-designed for northern lights viewing. Some Alaska hotels offer a northern lights wake-up call (upon request) to wake visitors when the lights are out.
