圣乔治 12月 天气

Regulars are consistent that rain here typically arrives as a short, sharp shower that clears quickly rather than settling in for a full day, and that a whole vacation of all-day rain would be genuinely unusual even though this sits at the tail end of the wet season. Our row backs the real wetness behind that framing, 106mm of rain across a striking 18.8 days, alongside warm, humid conditions, 30.8C reading as a hot 33C at 79 percent humidity, over 24.1C nights, and a real 30.4 kph wind. Regulars flag the sea as noticeably choppier this time of year, not ideal for snorkeling even on an otherwise sunny day. One regular's caution is worth keeping in mind broadly: historical patterns aren't as reliable a guide as they used to be, with rain showing up in dry season and sun in wet season more often lately. The sea holds a warm 28.2C. The record: 10 hours of sun and one of the cleanest air readings in this project, AQI 39.

Forum posters describe September temperatures in the mid-80sF (around 29-30C), with brief daily showers - typically 15-30 minutes, often first thing in the morning or overnight - that posters describe as a welcome cooling-off rather than a disruption, with a full washout day happening maybe once every couple of weeks. Posters note one visitor's mid-September trip specifically saw heavy but short-lived rain that cleared quickly. Posters are consistent that while September falls within hurricane season, Grenada sits outside the main hurricane belt, citing only about three major storms in the past 50 years as evidence the risk here runs genuinely lower than further north in the Caribbean. Posters describe September as a quieter month with fewer tourists and easier hotel bookings. Posters generally rate September as warm, occasionally rainy but rarely disruptive for St. George's, with meaningfully lower hurricane risk than much of the wider Caribbean.

Forum posters describe March as squarely in the middle of Grenada's dry season, running January through June, and consistently rate it a good time to visit despite what online forecasts sometimes show - posters are direct that there are no real storms this time of year regardless of what a weather app predicts. Posters flag the so-called Easter winds as a genuine feature of this period, cooling things down but also kicking up loose sand on the beach. Posters describe daytime temperatures typically in the high 20s to low 30sC with overnight lows noticeably cooler, and generally rate any rain that does fall as brief showers rather than extended wet spells. Posters consistently rate March as a comfortable, reliably dry time to visit St. George's.
