Climate Overview
Chile's climate is extraordinarily diverse across its 4,300 km length. The north is dominated by the hyper-arid Atacama Desert (essentially no rain, intense sun, cold nights). Central Chile including Santiago has a Mediterranean climate with hot dry summers and mild wet winters. The Lake District receives abundant rainfall year-round. Patagonia in the far south has cold, windy, and unpredictable conditions year-round. Visitors must pack for the specific region they're visiting — not one climate fits all of Chile.

Seasonal Breakdown
Detailed information for each season.
🌸 Spring
Sep-Nov
Temperatures warm, wildflowers bloom in the Atacama after rare rains, and Torres del Paine opens its trekking season. Santiago has mild pleasant days (15-20°C) and occasional showers.
☀️ Summer
Dec-Feb
Peak season across Chile. Santiago is hot (28-33°C), Patagonia has its longest and most stable days, and Atacama is sunny but extremely hot by day. Easter Island is warm and humid.
🍂 Fall
Mar-May
Possibly the best season for Patagonia — autumn foliage turns Torres del Paine's lenga beech forests gold and red, crowds thin, and weather is still stable. Santiago cools pleasantly to 15-22°C.
❄️ Winter
Jun-Aug
Winter brings rain and cold to Santiago (5-12°C) with fog and smog issues. Patagonia is harsh with most refugios closed. Atacama is cold at night but spectacularly clear. Ski resorts near Santiago (El Colorado, Valle Nevado) are at their best.
