Tromsø sits inside the auroral oval roughly 240 nights a year and shows aurora at Kp 2 or 3. It is the most predictable base on the planet for a once-in-a-lifetime trip.
Best window: September to March. Statistical peak in February and March, plus the equinoxes (Sep/Mar) via the Russell-McPherron mechanism. December and January have longer nights but more clouds on the Norwegian coast.
Yellowknife (Canada) and Fairbanks (Alaska) have dry continental skies. Colder (-25 to -35°C in January), but the highest rate of clear nights on this list, near 90% over three nights.
