Traveller notes on St. John's in May
Notes from nearby Pointe-à-Pitre (103 km away)
St. John's doesn't have its own notes for May yet — these are about Pointe-à-Pitre, close enough to share the season.
Forum posters consistently describe Pointe-à-Pitre itself as a working city rather than a beach resort town, generally recommending visitors base themselves elsewhere on the island and treat the city as a day stop. Posters flag real weather variability across Guadeloupe's two halves - mountainous Basse-Terre can see scattered rain while flatter Grand-Terre, where Pointe-à-Pitre sits, stays sunny at the very same time. Posters generally recommend having an indoor backup plan, like the Memorial ACTe slavery-history museum, for a rainy stretch. Given the destination's largely urban, transit-hub role in most trip reports, May here should track Guadeloupe's broader early-wet-season warmth and humidity, with Grand-Terre's drier microclimate a real practical advantage over the mountainous side of the island.
Other months in St. John's
Forum posters describe October as usually Antigua's wettest month, though posters are quick to add that doesn't mean much by the island's generally dry standards - evenings stay warm and humid around 75F, days remain hot enough for sunbathing, and the island still sees roughly 7 hours of sunshine on an average day. Posters describe rain as often torrential when it comes but rarely long-lasting, and note Antigua's central mountain range creates a genuine 'dry side' and 'rainy side': the south and southwest see meaningfully more rain than the north and northeast, where St. John's itself sits, and which can go weeks without significant rain even in October. Posters are direct that October remains technically within hurricane season, adding genuine uncertainty on top of the routine rain pattern. Posters generally rate October as St. John's own driest-side experience of Antigua's wettest month, warm and mostly sunny with real but often brief rain and a background hurricane-season risk.
Forum posters consistently describe April as pleasantly hot and one of the drier months on an island that's already fairly dry overall, with daytime temperatures typically in the low-to-mid 80sF and evenings only a few degrees cooler. Posters are direct that any daytime rain usually passes quickly - a 'rain' forecast here typically means 10-15 minutes of showers followed immediately by sunshine again - and consistently warn not to trust online weather forecasts for Caribbean islands, which tend to over-predict rain. Posters also flag real geographic variation from Antigua's central mountain range, with a noticeably rainier south/southwest side and a drier north/northeast side that can go weeks without rain. Posters generally rate April as a good, comfortable month to visit St. John's and the wider island.
