Helsinki lies at 60.17° N in Uusimaa, Finland, about 710 km south of the Arctic Circle. At a geomagnetic latitude of about 57.7°, Helsinki needs a geomagnetic storm: the oval's edge only reaches this far south from about Kp 5, and the aurora usually stays low on the northern horizon. Roughly 9% of dark, clear nights show some aurora, far fewer than in Lapland.

Nights with at least two hours of real darkness run from early August to early May; in the light summer nights between, the aurora cannot be seen. Around the winter solstice the sun is more than 12° below the horizon for about 14.5 hours a day.

Clouds decide most nights, and we have no long-term cloud record near Helsinki. The hourly score above uses the live cloud forecast for this exact spot, so on a storm night it shows whether the sky is open where you are.
