San Pedro de Atacama in January
Not the best time
Peak summer chaos with sweltering heat and packed attractions. The worst crowds you'll face all year, but tours still run smoothly if you book early and start before sunrise.
Weather
January brings peak summer heat to the Atacama, with scorching days that can hit 30°C+ and surprisingly cool nights. The air stays bone-dry with almost zero humidity, but afternoon thunderstorms occasionally roll in from the Andes. UV exposure is brutal at this altitude.

All Months
April through October brings the best weather – daytime temperatures hover around 20°C while nights drop to near freezing. The dry season means clear skies perfect for stargazing and photography. Summer (December-February) gets uncomfortably hot during the day, reaching 30°C+, but offers warmer nights for camping under the stars. Winter nights can hit -10°C, so pack serious cold-weather gear if you're visiting June through August. The rainy season barely exists here – San Pedro receives less than 15mm of precipitation annually. But when it does rain (usually January-March), flash floods can make some roads impassable. Book accommodations well ahead for July and August, when Chilean winter holidays bring domestic crowds.
