<%@ page language="VB" contenttype="text/html" responseencoding="iso-8859-1" %> There are two different climates: the one of the region named Andes Patagónicos and the other of what we call Patagonia extrandina.
The first one is a very cold and wet weather, with winter precipitations (more than 1000 mm. per year) generated by winds from the West.
Patagonia extrandina has arid cold climate. This is a very dry weather, precipitations are inferior to 200 mm. per year, because winds from the South Pacific Ocean release humidity in the mountains and when they arrive to this zone they are dry. These are constant winds, with powerful gusts that are typical of this climate and main agent of erosion.
Sporadicly, polar wind is part of this weather.
Average temperatures are inferior to 10º C and more elevated on the coast and lakes zone, in this last case because water acts like mirror, causing a moderating effect; winter presents low temperatures. In Sarmiento there have been temperatures of -35º C. The region named Patagonia extrandina presents great thermal amplitudes.
