When to travel
Sri Lanka has a tropical monsoon climate. The average temperature is 30 °C with 90% humidity. The water temperature is constant 27 °C. From May to October, the south-west monsoon brings heavy rain fall on the west and south-west coasts. During this time, the sea is churned up and becomes unsuitable for swimming. Therefore, the best time to travel to the west and south west is between October and April. In the central highlands, it is the driest between January and May.
