Key Factors Affecting Timing in 2026

Daytime temperatures stay mild (15–20°C), but nights can drop below freezing, especially from June to August. Dry season (May–Oct) is best for trekking with clear skies.
Coastal Regions & Deserts: What to Expect
Peruvian and Chilean coastlines have mild winters (12–18°C) and warm summers (22–28°C). Atacama Desert remains dry and sunny almost all year, with rare rainfall but chilly nights.
