What March feels like in Colombo

March is part of Colombo's dry season, when rain totals drop well below the wet months. Afternoons are hot, so sightseeing works best in the morning or evening. There is little difference between day and night: nights stay warm, and evenings feel much like the afternoon. Thick, humid air means clothes cling and the heat feels stronger than the number.

Rain in Colombo in March
