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 Longyearbyen looks mostly cloudy (about 51% cloud on average). The aurora is best viewed away from town lights with a clear view toward the north.

Step just outside town toward Adventdalen valley; in deep polar night the whole day is dark. Guided trips carry rifles for polar-bear safety — don't wander far alone.

These are probabilistic viewing odds, not a guarantee. We build them from public NOAA space-weather forecasts (planetary Kp + the OVATION oval model) and Open-Meteo cloud forecasts — both can change fast, and clear skies and solar activity are inherently uncertain. The aurora is a natural phenomenon; some clear, active nights still disappoint, and some quiet nights surprise. How we compute the score.
