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 Ushuaia looks overcast (about 80% cloud on average). The aurora is best viewed away from town lights with a clear view toward the south.

Head out of town along the coast or up toward the Martial Glacier; you want a clear southern horizon over the Beagle Channel. Patience and a strong-storm alert are essential this far from the oval.

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.
