In general, the spring and summer seasons in the Southern Hemisphere (October-March) are characterized by long days when weather is warmer and drier. The climate in Patagonia is similar Tasmania; in the summer you can expect some warm sunny weather, as well as cold, rainy and windy days. Geographical diversity throughout the rest of Chile gives rise to several distinct climatic regions with wide extremes of temperature, sunlight and rainfall. Although the season for adventure travel in Patagonia is limited, you can travel in many areas of northern Chile throughout the year. The prime season in Patagonia is October-March when average daytime highs range from 18°C in the sun to low 4°C. Night temperatures are typically in the mid to upper -1°C but occasionally -7°C. The weather is extremely erratic in Patagonia. It varies from warm sunshine to drizzle, rain and/or sleet in a matter of minutes and returning to sunshine just as quickly. Wind is a constant factor ranging from strong breezes of 24-32km/h to gale forces up to 96km/h. Clothing should be adaptable outdoor gear. The climate in Santiago is temperate and moderated by maritime air. Expect warm sunny days during summer (21-27°C in Dec-Mar) and cool cloudy weather in winter (10°C in June-August). The Andes region including the Lakes District from Puerto Montt to Bariloche (Argentina) has a cool mountain climate from October to April (10-13°C). The high Andes region of northern Chile is typically dry and clear especially in May-September. The Atacama Desert of northern Chile is always dry and suitable all year round.
