Santiago Climate & Weather

Santiago Climate and Weather


The climate of Santiago is Mediterranean, with typically hot, dry summers and mild, moist winters. In summer, November to February, average temperatures hit highs of around 93°F (34°C). The summer months can be quite windy, with prevailing winds from the southwest. In winter, May to August, temperatures average around 52°F (11°C). Temperatures in winter seldom drop below freezing. Rain falls mainly during winter, which is a more humid season in Santiago. Snowfall is extremely rare in the city, although it is common in the Andes mountain range that looms above Santiago. Temperature inversions cause smog to be trapped in the valley for spells during the winter months, bringing heavy pollution. Unfortunately, the city is considered one of the most polluted in the world, largely due to its location in a natural bowl, and the smog is at its worst in winter. The best time to visit Santiago is in the summer months of December, January and February, although many people do visit in the winter to enjoy the skiing.
