In the Southern Hemisphere the seasons, weather and climate are reversed from those in the Northern Hemisphere. While we are experiencing winter in the United States and Europe, in Patagonia , Chile it is summer.

Weather in 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.

Here the Forecast for Patagonia, from south to north!

+ abouth weather…
Generally, Patagonia weather is dominated by two factors. The first is the strong and highly predominant westerly wind and the second is the Andes, as they build a barrier to the west winds and the moisture these winds carry, in a manner comparable to the Rocky Mountains in North America but on a much bigger scale. This is mainly due to the Antarctic influence, also called the “Antarctic accent”.

Going through Patagonia from west to east, it can be observed that over a distance of only 60 miles the precipitation regime changes from fully temperate Patagonian Rain forest (200 inches of rainfall annually) to semi-arid Patagonian Steppe (20 inches of rainfall annually), due to the effect of the Andes barrier, as shown in the figure below.

As you can see Patagonia weather patterns are amazingly complex, and so it’s virtually impossible to answer the common question “When can you expect the best weather?” Throughout our season the temperature can range from 40 to 90 F, with winds from 0 to 50 miles per hour. It could be cold and wet or hot and sunny, so it’s best come prepared for any conditions. We will provide you with all the information on what to bring, once you book with us.
