圣约翰 3月 天气

March in Guadeloupe is still high season and still 80 to 85F most days. The forum's framing of the rain is that a forecast showing showers means very little here - they pop up at any time and seldom last an hour, often much less - though one March visitor had rain on three days of six, including a proper downpour, and still snorkelled at Malendure. Our row's 18.1 precipitation days carrying only 53.7mm is that pattern in figures. Two other things to know: sargassum runs March to October and varies hugely year to year, and the Basse-Terre beaches are bigger and quieter than Grande-Terre's but rougher. The record: 26.9C days that feel like 30C, 23.9C nights, 11.2 hours of sun and a 26.6C sea.

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.
