Sri Lanka weather & when to go: December

December overview

Along the western and southern coasts the rainfall continues to decline as south-west monsoon fast becomes a distant memory. As the recent unsettled weather fades away, plenty of sunshine and dry days are expected as peak beach conditions return (avg temp: 30 °C).

Up in the hills the rainfall also drops slightly, although it’s still wet and evenings continue to be chilly. December marks the beginning of the Adam's Peak pilgrimage season, which runs throughout the dry season until May.  

Further north in the Cultural Triangle, rainfall is still high, although the peak figures of the previous month should have dropped considerably, especially by the end of the month (avg temp: 27 °C).

In the north and along the east coast, rainfall continues to be high as the north-east monsoon blows.
