Traveller notes on Bentota in January
Notes from nearby Colombo (59 km away)
Bentota doesn't have its own notes for January yet — these are about Colombo, close enough to share the season.
Colombo's forum calls January favorable — mostly sunny with light showers rather than sustained rain, and warm calm seas good for swimming. Regulars flag the northeast monsoon as still active this time of year, so the north and northeast of the island see more rain than the south-west coast where Colombo sits.
