Chile Weather, climate and geography

Due to its long coastline, clearly Chile’s weather is extremely diverse and unpredictable although it is seasonal in much of the country. Summer runs from December to February, and winter from June to August.

It is difficult to pinpoint temperatures ranges for the country as a whole as they’re so variable. There’s the dry, arid Atacama desert in the north where temperatures reach a maximum of 32°C (90°F) and can drop to -2°C (28°F). Chile’s central region has a Mediterranean feel with a cold, wet season from May to August, while it is usually always cool and damp in the south. Easter Island has its own humid sub-tropical temperatures, while much of the south, from Region VII down has a very high annual rainfall.

Arica, Iquique, Antofagasta, La Serena and Coquimbo are the principal summer beach hubs in the north for local tourists, while Pucón in the south sees high tourism numbers from January to March. Due to its proximity to Santiago, Viña del Mar and Valparaíso beach areas see plenty of sunshine and beach bums during the summer, often filling up with neighbouring Argentinians. As Chile is in the southern hemisphere, the ski season takes place between June and August.

In terms of visiting Patagonia and south, the summer months from December to March are ideal as it is warmer for trekking and other outdoor activities. November and April are quieter times in terms of tourism but the weather is less dependable. It isn’t advisable to visit the south from the end of autumn to the end of winter - May to September - as many trails close due to bad weather and strong winds and waterways ice over. However, places in the north, such as the Atacama, can be visited all year round.
