Cuaca Galle (Unawatuna) di Oktober

Regulars are direct this technically falls within monsoon season here, though it's genuinely unlikely to rain the entire day, rain more commonly arriving in the late afternoon and evening rather than settling in from morning. Our row backs that hot, genuinely wet read, 29.1C reading as a scorching 34C, over 26.1C nights feeling 29C, with a substantial 205.1mm of rain across 28.4 days and humidity at 85 percent. Regulars are consistent this remains genuinely hot and humid throughout regardless of the rain pattern, sun protection and hydration the standard advice for daytime activity. The sea sits at a bath-warm 27.9C. The record: 10.2 hours of sun, a 21.1 kph wind and AQI 42.

April sits about a month ahead of the southwest monsoon, which regulars date to the end of May, and they describe the run-up precisely: hot sunshine most of the day with an isolated downpour toward evening, not continuous rain. December through April is the in-season window for this coast, and April is its last, warmest stretch - our row reads 31.3C but as 39C at 83.9 percent humidity, with 201.2mm across 27.1 days, which is that isolated-downpour pattern rather than a wet month. After the 15th they warn the sea can turn rough even before the rain properly starts, a shoulder-season swell rather than a storm. Nights hold 25.8C, the sea 30.4C. The record: 10.4 hours of sun, an 11.9 kph wind and AQI 50.

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.

Our row for Galle counts 16.8 precipitation days in January, which looks like the wrong month entirely until regulars explain the timing. On this south coast you can expect three or four afternoons of heavy rain in a stay, and it arrives late: clouding up around half past four or five, with the serious storms after six once it is dark. The days work; the evenings get wet. January to March is the stretch they name for calm seas and good weather on the south and west coasts, with the dry season running Christmas to mid-April - though they are honest that December onwards has been wetter than the label suggests. Heat is the other factor: 29.8C over 24C at 83 percent humidity and almost no wind reads as 36C. The record: 148.6mm, 9.8 hours of sun and a 27.8C sea.
