Ushuaia in May

Summer (December to March) is peak season for good reason. Temperatures hit a pleasant 60°F, hiking trails are accessible, and wildlife is most active. But expect crowds and higher prices—hotel rooms can double in cost compared to winter. Late spring (November) offers a sweet spot. Weather's improving, crowds haven't fully arrived, and you might catch snow on the mountains while enjoying mild days in town. This is prime time for penguin colonies too. Winter (June to August) brings snow, shorter days, and a completely different vibe. Some tours don't operate, but you get the city mostly to yourself. Plus, it's the only time you can ski at Cerro Castor while looking out over the Beagle Channel. Just pack serious winter gear.
