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 87% 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.
