Rain season
Rio's wet season (November–March) brings intense afternoon thunderstorms that can be catastrophic. The city's steep hills and narrow ravines concentrate runoff rapidly, making landslides and flash flooding a serious risk — January is historically the highest-risk month. Annual totals average 1,200mm. The dry season (May–September) is reliably clear and mild.
