圣约翰 6月 天氣

Regulars are specific hurricane season officially opens on June 1st here, though the actual cyclone risk stays close to zero through June, July and August, real storm risk instead concentrated later, mostly August through October. Our row backs that hot, genuinely wet read, 28.8C reading as a hot 33C, over 25.9C nights feeling 29C, with a substantial 63.9mm of rain across 20.3 days and humidity at 78 percent. Regulars are consistent most of the actual rain falls in the higher inland regions and in short spurts rather than settling in, up to 8 hours of sunshine still typical on many days despite the official rainy-season label. This remains genuinely one of the hottest, most humid months of the year regardless of the calm storm outlook. The sea sits at a bath-warm 28.9C. The record: 11.6 hours of sun, a 21.1 kph wind and AQI 44.

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.
