Best time to visit Santiago for good weather
When is the best weather in Santiago? Monthly breakdown of temperature, rainfall, and sunshine hours — ranked by what actually matters for your trip.
Best month
March
The unmissable month: vendimia wine harvest, Lollapalooza, and perfect autumn temperatures.
↑March is the single most compelling month in the Santiago calendar. The vendimia — grape harvest — transforms the Maipo, Colchagua, and Cachapoal valleys within 90–150km of the city into a working festival landscape. Viña Santa Rita (Alto Jahuel, 35km south), Viña Undurraga (Talagante, 34km west), and the prestigious Almaviva estate all open for harvest visits. The regional Fiesta de la Vendimia events in the vine towns — Santa Cruz in Colchagua and Curicó further south — involve grape-stomping competitions, folk music, and local food in a genuinely Chilean celebration that precedes the international wine tourism by centuries.
↑Lollapalooza Chile (late March) at the Parque O'Higgins is one of South America's largest music festivals: 80,000+ attendance, four stages, an international lineup that competes with the North American event. The surrounding neighbourhood of Barrio Brasil and the fan culture around the event gives Santiago a temporary festival-city energy.
↑The temperatures in March are perfect: 27°C by day, cooling to 12°C at night. The summer haze begins to clear and the first rain of the year (8mm — minimal) washes the basin air. On clear March mornings, the Andes appear in extraordinary clarity — the snowcapped peaks of the Cordillera visible from the Cerro San Cristóbal viewpoint in Bellavista seem close enough to walk to.
