Northern Sights

When to come

The best time to see the northern lights in Denali and Healy

The northern lights are out all year. You need a dark sky to see them, and in Alaska that means late August to mid April. Nobody can forecast a display months ahead, but three things can be known: how long it is dark, where the moon will be, and how cloudy the month usually is.

Dark-moon weeks coming up

Seven nights around each new moon, when the sky is darkest. A strong display shows through any moon, so treat these as a good default, not a rule.

Dark hours are for the middle of each month, counted from when the sun is 12 degrees below the horizon. Usual sky is a long-term average from NOAA's climate records. It describes the month, not any one night.
