It gets dark enough for the aurora every night except from 2 May to 9 August, with up to 15 hours of proper darkness a day in midwinter. Counting the darkness, that makes about 88 hours in a typical year with both darkness and enough activity, most of them in September. The clouds decide how many of them bring an aurora.
