March is high for Santiago.
March is one of Santiago's best months — the fierce summer heat softens into warm, dry, golden autumn days (highs near 27°C/81°F) with cool, crisp nights. The city returns to its normal rhythm as holidays end, and crowds and prices ease from the summer peak.
The highlight is the wine harvest — vendimia season. Maipo, Casablanca, and the Colchagua Valley further south hold harvest festivals (fiestas de la vendimia) with grape-treading, food, and tastings. It's a wonderful, atmospheric time for a wine-country day trip.

Santiago in March — Full Picture
March is one of Santiago's best months — the fierce summer heat softens into warm, dry, golden autumn days (highs near 27°C/81°F) with cool, crisp nights. The city returns to its normal rhythm as holidays end, and crowds and prices ease from the summer peak.
The highlight is the wine harvest — vendimia season. Maipo, Casablanca, and the Colchagua Valley further south hold harvest festivals (fiestas de la vendimia) with grape-treading, food, and tastings. It's a wonderful, atmospheric time for a wine-country day trip.
The weather is ideal for the full city program — Cerro San Cristóbal, Sky Costanera, walking the Centro and Lastarria — without the midday intensity of January and February. Air quality is still good before the winter smog sets in.
Note: it's a genuine shoulder-season sweet spot — comfortable temperatures, harvest energy in the valleys, and better value than the summer peak. A light layer handles the growing day-night swing.
