Blue Whales, Coconut Tree Hill and a Lively Beach
A palm-backed bay on the south coast and the main port for whale watching: blue whales, sperm whales and dolphins from about November to April, when the sea is calm. Coconut Tree Hill, Parrot Rock and Secret Beach are a walk away; surf breaks at Weligama (learners) and Mirissa (reef). From May to October the south-west monsoon makes the sea rough and the boats stop.

When to go
Best time: December – April
Worth knowing
South-West Monsoon: Rough Seas
From May to September the south-west monsoon brings rain, wind and big waves to the west and south coasts: red flags and strong currents on most beaches, whale-watching boats stop, and many beach restaurants close. It rarely rains all day, and rooms are cheaper, but for swimming go to the east coast (Trincomalee, Pasikudah, Arugam Bay), which is in season.
Heads up
Inter-Monsoon Storms
October and November bring thunderstorms across the whole island and the risk of cyclones from the Bay of Bengal: Cyclone Ditwah at the end of November 2025 caused deadly floods and landslides, especially in the hills. Watch the Department of Meteorology's warnings (meteo.gov.lk) and keep a spare day.
Heads up
No Whale-Watching Season
Mirissa's whale boats run from about November to April; out of season the sea is too rough and they stop. In the summer months, whale and dolphin trips run from Trincomalee on the east coast instead.
Heads up
Peak Season Crowds
Late December to January is the busiest time on the south coast and in the hills: Galle Fort, Sigiriya and the Ella train are crowded and the best rooms sell out. Book rooms and reserved train seats early and climb Sigiriya at opening.
- Christmas and New Year peak — The south coast's busiest and dearest fortnight: beach hotels set minimum stays and gala dinners on 24 and 31 December, the Ella train and Yala jeeps sell out, and Indian holiday-makers add to the European winter crowds. Book rooms and reserved train seats by October.
