Rain season
Santiago has a classic Mediterranean climate — dry summers (November–March) with almost no rain, and wet winters (May–August) when Pacific fronts deliver most of the 300mm annual rainfall. The Andes block Atlantic moisture so all rain comes from the Pacific. Drought conditions in recent decades have reduced annual totals significantly.
