Traveller notes on Kingstown in May
Notes from nearby Castries (96 km away)
Kingstown doesn't have its own notes for May yet — these are about Castries, close enough to share the season.
May is the last month of the dry season here, which runs December through May, and regulars call the handover to the wet months an unremarkable one - the same hot days and nights with occasional showers, storms that come in fast and leave just as quickly. Our row backs that: 37.3mm across 11.4 days is a real but modest total. Air is 30.5C reading as 33C, though at 72.4 percent humidity it is milder than the number implies, and they credit the constant wind off the ocean, which our column carries at a genuine 24.1 kph. Nights hold 24.9C, the sea 28C. Prices ease and booking gets easier as the dry season's crowds thin out. The record: 11.7 hours of sun and AQI 48.
Other months in Kingstown
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.
