Patagonia is much cooler than the rest of South America. With diverse terrain ranging from glaciers to mountains and coastlines, the region sees extreme variations in weather. Average temperatures range from 9-18°C in summer and 0-6°C in winter, but sub-zero temperatures are common. The weather can be unpredictable at any time of year, and it feels much cooler when there are strong winds. Snow is possible towards the end of autumn (May), and continues into the winter with heavy snowfall down south and in the mountains.
