Check your trip date
Choose the month you arrive and the region you care about most. Coastal conditions in Sri Lanka flip almost completely between seasons, so your verdict depends on both.

How this is calculated
Coastal verdicts (go / mixed / skip) come from our region-by-region seasonal analysis of Sri Lanka's two monsoons. Temperatures, sea temperatures and rainfall are regional monthly averages. The traveller rating is the actual average review score travellers gave in that month across 353,633 real guest reviews. It is a happiness signal, not a weather forecast — a "mixed" month on the weather can still be rated highly by travellers who came prepared.
