10-day forecast, out to 14 days

where the models agree, and where they split

Heading to Sri Lanka? Sri Lanka, Sri Lanka, sits at 6.9°N in a tropical climate zone. The averages on this page are measured at Colombo, the main gateway for UK travellers; inland and mountain areas run cooler. Before you lock in outdoor plans, compare how the three global models - European (ECMWF), American (GFS) and German (ICON) - forecast Sri Lanka right now. Where they agree you can trust it; the days they split are exactly when a single weather app is least reliable. For a beach trip the rain and wind columns below matter most - that is what makes or breaks a day by the sea.

Best time to visit Sri Lanka
