ベントタ 11月の天気

Sri Lanka-forum threads on November weather (Colombo specifically among the destinations discussed) confirm it's the rainiest month of the year islandwide, though posters note the second half of the month usually runs better than the first. Coastal, low-lying areas like Colombo stay hot and humid enough that regulars advise against proper waterproof rain gear, an umbrella doing the job better without trapping heat against the skin. Showers, when they arrive, are heavy but limited to a few hours, and by some estimates roughly two-thirds of November days still deliver enough sunshine. Swimming on the open southwest coast is a bad bet this month, seas staying rough until at least mid-December. The record actually runs far wetter than the two-thirds-sunny framing suggests: 30.7C days feeling like a punishing 37C, 24.3C nights, a notably high 400mm across nearly 25 days, 86 percent humidity, a 29.2C sea and 8.1 hours of sun.

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.
