Patagonia

Weather

Argentine Patagonia sits in the Chilean Andes’ rain shadow, which blocks most Pacific storms. After heavy precipitation falls on the seaward Andean slopes, powerful dry westerlies gust incessantly across the arid Patagonian plains. Due to oceanic influence where the South American continent tapers toward the south, the region’s climate is generally temperate, but winter temperatures often drop well below freezing.
