Climatic map of the argentinian side of the Isla Grande de Tierra del Fuego.
Due to its latitude, the island has a cold oceanic climate. The influences from the surrounding ocean and the predominant winds from the west result in the climate being uniform throughout the province. Mean annual temperatures are low, with winter temperatures averaging close to 0 °C and summer temperatures averaging around 10 °C. The strong westerly winds from the Pacific Ocean increase the perception of the wind-chill or windchill factor. In the extreme south in the Beagle Channel which is surrounded by mountains rising above 100 m, winds can exceed 100 km/h. The island averages around 700 mm of precipitation per year which is fairly evenly distributed throughout the year with a slight maximum in Autumn. Snowfall is abundant throughout the island. Much of this island can be classified as within the Magellanic subpolar forests ecoregion.
