Santiago Climate

Set in a valley ringed by the Andes, Santiago has a Mediterranean climate (Csb) with a sharply defined wet and dry season. Summers (December–February) are dry and hot, typically 28–32°C under clear skies with virtually no rain, while winters (June–August) are cool and damp at 3–15°C, when nearly all the year's rainfall arrives. Winter temperature inversions often trap smog in the basin, degrading air quality, even as fresh snow blankets the Andean peaks right beside the city.

Frequently asked questions

When does it rain in Santiago?

Rain falls almost entirely in winter, from May to August. Summers are practically dry, with many months seeing no measurable rain at all.

Does it snow in Santiago?

Snow in the city itself is rare, but the surrounding Andean peaks stay snow-capped all winter, feeding ski resorts only about an hour's drive from downtown.

Why is Santiago's air often polluted in winter?

The valley terrain combined with winter temperature inversions traps pollutants near the ground, especially on calm days, pushing AQI readings high between May and August.

When is the best time to visit Santiago?

Spring (September–November) and early autumn (March–April) are most pleasant, with clear skies, mild temperatures of 20–26°C and cleaner air than in winter.
