Sri Lanka climate: when to go to Sri Lanka

The climate of Sri Lanka is tropical with two distinct seasons, a dry and a wet season. The country is influenced by two monsoons: the south-west monsoon blowing between May and August, is the most intense of the two and brings rain along the southern and western coast and central highlands, and the north-east monsoon blowing between October and January, bringing rain along the coasts of northern and eastern Sri Lanka.

Areas in the north and east of the country are the most arid and receive between 600 mm and 1,200 mm of rain a year. The south-west coast and mountain slopes of the southern central highlands are the most rainy areas, the capital Colombo, located along the southwestern coast, receives around 2,500 mm of rain a year, the most rainy months in Colombo are those between September and November and also April and May, the driest months are January and February. As in all areas near the equator, are also not negligible the zenithal rain, that is the increase of rainfall that exists in the periods immediately following the steps of the sun at zenith, that is April-May and October-November.
