Traveller notes on Ushuaia in January
January is Ushuaia's summer, and the forum's figures match the record almost exactly — about 13°C by day and 6°C at night, with 17–20°C possible and near-freezing equally possible. What regulars stress is that temperature is not the story: deep storms crossing the Drake Passage bring gale-force winds across Tierra del Fuego even in midsummer, and on those days it feels wintry. Rain is frequent and spread fairly evenly through the year, and posters describe getting every kind of weather in a single day — sun, cloud, rain, wind. Layers, and a genuine windproof shell.
