The general year-round temperature does not vary much. The two monsoons...
- South West: May/June and October / November
- North East: November to March
...are distinct, meaning there is always a sunny beach. For more weather details see the climate review. Global warming has affected Sri Lanka too and the weather patterns are unpredictable at times. Monsoons can be short heavy showers or light drizzle all day.
December to March is the busiest season, ie more crowded, more expensive and liveliest atmosphere. For diving here, the water is calm and clear during this period. The Central Highlands – walking, cycling, bird watching etc –are cool and mainly dry Dec-April.
July to September are perfect months for those who don’t like intense heat and humidity but enjoy the odd day sunbathing. After the Spring monsoon, the plant life and white water rafting are also at their best.
The South East Coast now offers good beaches, diving and surfing from May to September.
