Ilulissat northern lights: questions
Yes. Ilulissat sits at 73.5° magnetic latitude, where auroras show on almost every clear night, even when activity is quiet. In 2015–2025 it averaged 123 good nights a year: clear, dark and active enough.
October: a 4-night stay then had at least one good night 95% of the time. Nights are dark enough from September to March. The best hours are usually around local midnight.
Hardly any. Ilulissat sits at 73.5° magnetic latitude, under or even poleward of the usual auroral oval, so auroras can show at Kp 0–1. We worked that out with a rule calibrated against the Finnish Meteorological Institute's sighting statistics. On quiet nights look north or straight up; on active nights the aurora can sit south of you.
In October, 2 nights gave 80%, 4 nights gave 95%, 7 nights gave 99% odds of at least one good night (2015–2025). Clouds come in spells, so more nights help more than you might think.
Every 10 minutes we take NOAA's Kp forecast and MET Norway's hourly cloud forecast for Ilulissat, add the sun and moon, and score each hour of tonight. The verdict is the best hour. How it works explains the calibration.
