December to March are the best time to visit the west and coast and south-central highlands, while the east coast has Sri Lanka's best weather between May and September. March and August offer consistently settled weather across the bulk of the island.
Whatever time of the year you travel, the Sri Lanka climate ensures that with skill and knowledge you can arrange a satisfying itinerary to chase the best of the weather. Check out our month-by-month guide below to discover the best times to visit Sri Lanka.
In Colombo and the west coast, noon temperatures range between 28-32C and peak in April before the seasonal rains. It can be slightly hotter in the Cultural Triangle and on the east coast. Kandy's daytime average is around 24C and average temperatures further into in the hills range from a daytime peak of 23C to a nightly low of around 9C.
Humidity ranges between 70-90 percent in Colombo, lower in the highlands and cultural triangle. Ocean breezes also moderate temperatures on the coast.
Rainfall is becoming increasingly unpredictable. Sri Lanka averages about 240cms a year, which explains its beauty, but much of the rain falls in short, heavy bursts, often at night, and figures vary widely from region to region. The north and east of the island represent the Dry Zone, with the far north-west and south-east the driest of all. The western slopes of the central highlands, inland from the coast, are the wettest.
Sri Lanka monsoons
Sri Lanka lies 400 miles north of the equator and is affected by two monsoon seasons caused by winds originating from the Indian Ocean and the Bay of Bengal. The monsoon weather patterns in Sri Lanka ensure that some coastal waters are always in season for swimming, snorkelling, and diving.
The main south-west monsoon (Yala) originates from the Indian Ocean and brings most rain to Colombo, the south, and west coasts and during May/June.
The weaker north-east monsoon (Maha) brings rain from the Bay of Bengal and affects the far north and east between December and February. In this dry zone, the monsoon makes up the vast majority of its rain for the year.
There are also inter-monsoon rains, usually in October and early November when heavy rain is possible anywhere across the island.
