Cloud outlook & dark hours
Cloud cover is the dealbreaker: a strong aurora under an overcast sky is a no-show. Tonight's dark-hours window in Senja looks mostly cloudy (about 70% cloud on average). The aurora is best viewed away from town lights with a clear view toward the north.
Ersfjord beach and Tungeneset are the iconic foregrounds. Senja's mountains can trap cloud, so a flexible chase or a multi-night stay raises your odds.
