Rain season
São Paulo's wet season (October–March) brings intense afternoon thunderstorms — brief but capable of dumping 50mm or more in an hour. Flash flooding (alagamentos) that paralyses traffic is a regular event after heavy rain. June–September is the dry season. At 760m elevation, evenings are cool year-round despite the tropical latitude.
