طقس بينتوتا في ديسمبر

December is the month the south-west coast changes over, and regulars put the turn late rather than early: the coast dries out a lot from mid-December, and the season proper starts just before Christmas. Some years the first half stays very wet, and they report Decembers where it rained throughout, or where the dry days still carried a sea too rough and windy to enjoy until January. Our row reads that first half: 186.2mm across 21.8 precipitation days, the wettest in this batch. Heat is steady at 30.1C reading as 36C at 84 percent humidity, with a 28.6C sea. For the most reliable south-coast beach weather they name February and March instead. The record: 9.6 hours of sun, a 10.6 kph wind and AQI 57.

Bentota forum threads describe August as bright and sunny most mornings, with cloud building through the afternoon and a real chance of showers by evening - not an all-day washout, but genuinely wet stretches happen too, and this coast sees frequent rain days through the month. The monsoon's bigger effect here is on the sea rather than the sky: ocean swimming turns unreliable due to rough surf and strong currents, though Bentota's sheltered lagoon and river keep watersports viable even on rough-ocean days. Forum consensus was that this window is still workable for a trip, just with beach plans built around the lagoon rather than open water.

Forum posters place February squarely within Sri Lanka's preferred southwest-coast season (mid-December to mid-April, plus July to mid-September), and call it typically a drier month overall. That said, posters are candid the weather can still flip within a single day - sunny for hours, then an hour or two of genuine downpour - so a light rain jacket is standard advice even during the 'dry' stretch. Wind is described as generally mild in February, with just a light, steady sea breeze rather than the stronger gusts some other months bring, making conditions comfortable for beach time along this stretch of coast.
