The Tierra del Fuego region has a subpolar [[oceanic climate]] ([[Köppen climate classification]] ''Cfc'') with short, cool summers and long, wet, moderately mild winters: the precipitation averages {{convert|3000|mm|in|0|abbr=on}} a year in the far west, but precipitation decreases rapidly towards the eastern side. Temperatures are steady throughout the year: in Ushuaia they hardly surpass {{convert|9|°C|°F|sigfig=2}} in summers and average {{convert|0|°C|°F|sigfig=2}} in winters. Snowfall can occur in summer. The cold and wet summers help preserve the ancient [[glacier]]s. The southernmost islands possess a sub-antarctic climate typical of tundra that makes the growth of trees impossible. Some areas in the interior have a polar climate. Regions in the world with similar climates to southern Tierra del Fuego are: the [[Aleutian islands]], [[Iceland]], the [[Alaska Peninsula]], the [[Faroe Islands]], [[Macquarie Island]], and the [[Heard and McDonald Islands]].
