Geography and Climate
About 18 kilometers west of Ushuaia, Parque Nacional Tierra del Fuego hugs the Chilean border as its 63,000 hectares stretch from the Beagle Channel north across Lago Fagnano (Kami). Elevations range from sea level to 1,450 meters on the summit of Monte Vinciguerra.
The park has a maritime climate, with frequent high winds. Rainfall is moderate, about 750 millimeters per year, but humidity is high, as cool temperatures inhibit evapotranspiration—the summer average is only about 10°C. The record maximum temperature is 31°C, while the minimum is a fairly mild -12°C. At sea level, snow rarely sticks, but higher elevations have permanent snowfields and glaciers.
