Aurora forecast for Tromsø — the next 4 nights

A ✓ means the forecast Kp clears Tromsø's Kp 1 visibility threshold — but clear skies still decide the night.

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 Tromsø looks overcast (about 98% cloud on average). The aurora is best viewed away from town lights with a clear view toward the north.

Coastal cloud is the enemy here, so the best move is a guided chase that drives inland (toward Finland or the Lyngen Alps) to find a clear patch. On a clear night in town, head away from the centre to Telegrafbukta beach or up the Fjellheisen cable car.
