Northern Lights in Alaska — What You Need to Know

Alaska is one of the best places on Earth to see the aurora borealis. The northern lights happen when charged particles from the sun hit Earth's atmosphere, creating curtains of green, purple, and pink light that dance across the sky.

Fairbanks sits directly under the "auroral oval" and sees aurora on most clear nights from September through April. Anchorage, Palmer, and the Mat-Su Valley need stronger activity but still get spectacular shows several times per month. Denali and Talkeetna are sweet spots between the two. Juneau needs a genuine solar storm, but when it happens, aurora over the ocean is unforgettable.

Four things matter: strong solar activity (we track this), clear skies (we check the weather), darkness (only visible at night), and moon phase (a bright moon washes out faint aurora). Alaska Glow combines all four into one simple answer for each location.
