Fairbanks, Alaska is North America's most reliable aurora city — arguably the most accessible high-latitude aurora destination in the Western Hemisphere. At 64.8°N directly under the auroral oval, with a dry interior continental climate that delivers exceptional clear-sky statistics (clear or partly cloudy on 60%+ of winter nights), Fairbanks has built an entire aurora economy around what the sky offers. The Chena River State Recreation Area, 45 minutes from downtown, is the premier dark-sky site, while Cleary Summit and Murphy Dome are classic favourites.
The aurora season in Fairbanks runs late August through late April — an extraordinary 8-month window matched only by Yellowknife globally. The interior Alaskan climate, cut off from Pacific moisture by the Alaska Range, produces genuinely dark and clear nights on a regularity that makes it statistically competitive with northern Norway for aurora viewing.
Anchorage, 360 km south of Fairbanks at 61.2°N, requires KP 3–4 for regular aurora. Hatcher Pass, an hour north of Anchorage, is the preferred dark-sky site. Seattle, at 47.6°N, is a major-storm destination only — KP 6+ is needed for realistic aurora chances from the Pacific Northwest.

Late August through late April for Fairbanks — the longest aurora season of any major city on Earth.
