Sri Lanka weather & when to go: May

Sri Lanka May weather overview

As the monsoon winds start blowing from the Indian Ocean and Bay of Bengal, they bring rain to the south-west corner of Sri Lanka: Galle, the southern beaches, the west coast and also into the hill country. Despite this, plenty of sunshine punctuates the short, sharp showers, especially during the first half of May.

May’s weather in detail

Swimming in the sea on Sri Lanka's south and west coasts during May is often not recommended and many hotels will have their red flags out to indicate that sea bathing can be dangerous at this time. On the other side of the mountains however, things are brightening up on the east coast (avg temp: 29 °C), so for R&R time in May and the best chance of sunshine, head to the east coast beaches. 

Temperatures remain high in the Cultural Triangle and also Kandy (avg temp: 32 °C), with minimal rainfall. The Tea Country region also sees minimal rainfall and pleasant temperatures that hover around the mid-20°C's. May marks the end of the Adam's Peak pilgrimage season.
