Sri Lanka in May
Monsoon on the south coast — head east and north instead
The southwest monsoon arrives in May and the south coast gets its heaviest rain of the year, with rough seas and red flags on many beaches. It's a great month for the cultural triangle and east coast, and prices on the south coast drop sharply.
Weather around the island in May
South & west coast
WetHeavy rain spells and big swells. Swimming is unsafe on many beaches; some cafés close.
East coast
GreatDry, sunny and calm. Peak beach season in Trincomalee, Nilaveli and Pasikudah.
Hill country
MixedWet on the western slopes. Ella and the eastern side stay drier.
Cultural triangle
GreatDry and hot. Great for Sigiriya, Dambulla and Polonnaruwa.
The sea on the south coast
Rough. Rip currents are a real risk on exposed south coast beaches — only swim where locals do, and never when flags are up.

Coming south in May?
It's not peak beach weather, but the south coast is far from closed. Expect quieter towns, lower prices and rough seas, so choose places with plenty to do on land.
What to pack
- A proper rain jacket
- Sandals that can get wet
- A dry bag for electronics
Local tip
✦ Vesak is the best time to see Sri Lankan generosity — join the queue at a dansal for free rice, curry or ice cream. It's not considered rude to accept.
