Hot days, with little relief after dark

March is Galle's warmest month, so choose it for heat rather than gentle warmth. Compared with London's March daytime average of 10.5°C, Galle feels markedly hotter, and humidity of 81% makes light, loose clothing a sensible choice. Temperatures reach 30°C on 37% of days: plan more active time for the morning and leave room for shade and breaks around midday. Nights average 24.7°C, so do not expect the evening to feel cool. Breathable nightwear and accommodation with cooling are sensible priorities. This suits travellers who enjoy sustained warmth; if sticky nights or humid daytime conditions wear you down, the heat is a real drawback.

Warm swimming weather, but allow for rain

The sea averages 29°C, making March well suited to travellers who prefer warm water for swimming. The catch is that beach weather is not reliably dry: rain occurs on about 20 days, so keep plans movable and pack a light waterproof that will not feel too heavy in the heat. There are about 5.1 hours of sunshine within 12 hours of daylight, so expect a mix rather than uninterrupted sun. Rainy days do not necessarily mean a whole day indoors, but you should not build your holiday around clear skies either. Sea temperature favours swimming; it does not tell you whether conditions are safe, so check locally before entering the water.
