Meteo Kingstown (Saint Vincent) in aprile

February, March and April are the driest months here and April is both the hottest and still high season - regulars describe good breezes, plenty of hot sun, middling humidity and some passing showers. Our row's 12.4 precipitation days spread just 34.2mm between them, under three millimetres a day, which is exactly what a passing shower measures. The trade winds at 22.8 kph are why 30C reads as only 32C. On sargassum they give a rule rather than a forecast: April is usually a low month for it, and the west coast is rarely affected at all, so a west-coast base removes most of the risk whatever the season does. The record: 23.9C nights, humidity 71 percent, 11.5 hours of sun, a 27.2C sea and AQI 46.

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.
