Sundsvall lies at 62.40° N in Västernorrland, Sweden, about 463 km south of the Arctic Circle. At a geomagnetic latitude of about 59.5°, Sundsvall needs a geomagnetic storm: the oval's edge only reaches this far south from about Kp 4, and the aurora usually stays low on the northern horizon. Roughly 13% of dark, clear nights show some aurora, far fewer than in Lapland.
Nights with at least two hours of real darkness run from mid-August to late April; 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 Sundsvall. 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.
