Pogoda Kingstown (Saint Vincent) — grudzień

Regulars are specific this counts as peak season here, calm seas and minimal seaweed the norm, any rain typically arriving in short bursts lasting a few hours at most rather than settling in for a full day. Our row backs that hot, genuinely wet read, 29.1C reading as a hot 31C, over 23C nights feeling 25C, with 41.8mm of rain spread across 14.3 days and humidity at 75 percent. Regulars are consistent a beautiful, sunny, breezy stretch in the mid-80s Fahrenheit is a common report even in the technically coolest month for locals. Genuinely excellent conditions overall make this one of the most popular windows to visit. The sea sits at a bath-warm 27.9C. The record: 10.2 hours of sun, a 23.9 kph wind and AQI 39.

There isn't much Kingstown-specific forum detail for September, so this leans on the broader Eastern Caribbean pattern posters describe: wet summers, dry winters, with September squarely in the wetter half of the year and a real (if not overwhelming) chance of rain most days. Nearby island forums in the same season describe daytime highs in the mid-to-high 20s C when there's no active storm system nearby, which lines up with St. Vincent's own numbers. It's hurricane season here too, so it's worth keeping an eye on the tropics rather than assuming clear skies for the whole trip.

Detailed month-specific trip reports for Kingstown are limited on the forum, though one visitor discussing safety mentioned a March visit without any weather complaints, and another mentioned attempting a La Soufriere volcano hike in March. Posters discussing St. Vincent's weather more broadly note that June and July bring good weather despite technically falling in the rainy season, implying the December-to-May dry season, which March sits within, should be more reliably dry still. Given the limited destination-specific detail, this note leans on that broader seasonal pattern: March falls in St. Vincent's comparatively drier, cooler half of the year, ahead of the wetter hurricane-season months from June through November.
