Colombo's Climate
Set on Sri Lanka's southwestern coast, Colombo has a hot, humid tropical climate that stays remarkably steady year-round, with temperatures hovering between 26 and 32°C. The city is shaped by two monsoons: the southwest monsoon brings heavy rain from May to September, followed by inter-monsoonal downpours in October and November. There is no real cold or fully dry season; instead, expect persistently high humidity and short but intense tropical afternoon thunderstorms.
