Climate

Chile is a remarkably-shaped country, extending 2600 miles between 22 and 55 degrees South, but having an average breadth of only between 100 and 200 miles.The east of the country is very mountainous, with peaks up to 16,000 feet. South of Santiago the mountains are lower and more broken, but the whole country is rugged with hundreds of small offshore islands.

Much of Chile therefore has a mountain climate with perpetual snow and glaciers. Precipitation is light in the northern mountains, and so the snowline is high. Away from the mountains, the north is a desert. Most of the population lives in the lowlands of Central Chile, whilst the southern part of the country is rugged and densely forested with a cool wet changeable climate.

Northern Chile is one of the world’s driest regions. Here, despite being almost rainless, the weather is often cloudy and cool. Annual average rainfall totals can be as low as 14 mm. Average daily maximum temperatures range from 17 C (63 F) in July to 28C (82F) in March. Central Chile has a Mediterranean climate with warm and virtually rainless summers, whilst the winters are mild and moderately wet. Frost and snow occasionally occur inland, but are rare on the coast.

In Santiago, daily average sunshine hours range from 3 in June and July to 11 in January and the daily average maximum temperatures range from 14 °C (58 °F) in June to 29 °C (85 °F) in January.

Southern Chile tends to be wet all year round, featuring frequent disturbed, changeable weather.

Annual rainfall can be as high as 5000 mm (200") much of which falls as snow farther south and on the higher mountains. On the coast, winters are rarely very cold, but summers are cool and cloudy.

At any time of year, Chile offers tourists something special. In springtime (September through November), Santiago and the central area of the country are splendid, whereas summer (December through March) is the ideal time to enjoy the beaches of Viña del Mar and the natural environment of Torres del Paine National Park, in Chilean Patagonia.

Winter (June through August), on its part, offers the ideal season of the year for skiing and snowboarding enthusiasts, who happily coast along the ski runs in the snowy valleys on the outskirts of Santiago, the country’s capital city.  

On Easter Island the weather is influenced by winds and ocean currents, resulting in an average annual temperature of 20° Celsius, with showers the whole year round, and May being the month of greatest rainfall.

On the other hand, the Juan Fernandez Archipelago has an average annual temperature of 15.4° Celsius and an average relative humidity of 76.5%. The best time of year to visit Chile’s interior is from October to February, when rainfall drops considerably
