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 Alta looks overcast (about 91% cloud on average). The aurora is best viewed away from town lights with a clear view toward the north.

The Sorrisniva area and the road up to the Haldde observatory are classic dark-sky spots. Inland location means fewer clouds — check the cloud line before driving toward the coast.
