Aurora Viewing Guide
Quick Answer: Juneau in United States sits at 60.8° geomagnetic latitude, requiring a minimum KP index of 4 for aurora visibility. The best viewing months are Sep to Oct and Mar, with up to 16 hours of darkness during peak season. Average cloud cover is 70% during aurora season, and the area has Bortle Class 4 dark skies.
Alaska's capital city is surrounded by the Tongass National Forest and backed by the Mendenhall Glacier. While Juneau's coastal location brings more cloud cover than interior Alaska, the combination of glacier, mountain, and marine foreground elements creates extraordinary aurora compositions when skies clear. The Mendenhall Glacier visitor area and Auke Bay are popular viewing spots.
At a geomagnetic latitude of 60.8 degrees, Juneau requires a minimum KP index of 4 for aurora to become visible. NOAA describes that activity level, "Active", as: Strong aurora display. Visible across much of Scandinavia and northern North America. Multiple colors and dynamic movement. Average cloud cover here during aurora season is 70%, on the higher side, so plan for at least 3 to 4 nights to improve your odds of a clear sky.

These are the curated viewing locations in and around Juneau. Each spot lists its type and light pollution level, with GPS coordinates, a Bortle class, and accessibility notes where available.
The viewing area facing Mendenhall Glacier and Mendenhall Lake. When skies clear, aurora above the glacier face creates extraordinary compositions unique to southeast Alaska.
A small harbor and beach area north of Juneau. The bay opens toward Lynn Canal with relatively dark skies compared to downtown, and the calm water provides reflections.
A coastal recreation area roughly 45 km north of Juneau. The beach faces Lynn Canal with mountains on both sides and far less light pollution than the city.

Yes, Juneau is a good location for viewing the northern lights. You need a minimum KP index of 4 here. The best months for viewing are Sep to Oct and Mar.
Juneau requires a minimum KP index of 4 to see the northern lights. NOAA classifies KP 4 activity as "Active", occurring occasional (4% of nights). Higher KP values produce brighter aurora that covers more of the sky.
The best months to see the northern lights in Juneau are Sep to Oct and Mar, when up to 16 hours of darkness are available each day. Give your eyes time to adjust to the dark before judging whether aurora is visible.
Start with ISO 1600 to 3200, an aperture of f/2.8 or wider, and a shutter speed of 8 to 15 seconds. Use a wide-angle lens (14 to 24mm) on a sturdy tripod, and focus manually on a bright star or distant light before the aurora appears.
