Why Oulu

Northern Finland's largest city still sees frequent aurora once you reach the coast or nearby islands.

How much activity you need here

At 65.0° geographic latitude, aurora typically becomes visible here once the planetary Kp index reaches about 1. Stronger geomagnetic storms push the oval overhead and light up more of the sky.

Best time to go

The northern aurora season runs from late August to mid-April, when nights are long enough to be truly dark. Around midwinter the sky can stay dark almost all day; in high summer the midnight sun makes viewing impossible.
