Weather

Sri Lanka does not have one travel season

Two monsoons run in opposite directions. The south-west monsoon (roughly May to September) wets the south and west coasts while the east stays dry; the north-east monsoon (roughly October to January) reverses it. Pick a region and a month to see what you would actually get.

How to read this

Figures are typical conditions drawn from published climate patterns for each region, not a forecast. Rain in the hill country usually arrives in the afternoon; on the coasts it tends to come in longer spells. Always check the Department of Meteorology forecast for the days you are travelling.

Verification

Regional weather guidance is reviewed every 180 days against the Department of Meteorology and Sri Lanka Tourism sources. This page is indicative planning information — conditions vary year to year.
