Vejret i Road Town (Tortola) i maj

BVI's forum calls September a genuine 'roll of the dice' - it's both rainy season and the most active stretch of Atlantic hurricane season, running roughly early September through mid-October, though plenty of visitors have had excellent trips with no storm anywhere near. Day-to-day rain, when it does show up, tends to be a fast-moving, localized shower lasting minutes rather than hours - it's entirely normal for one side of Road Town to get soaked while the other stays sunny. Some restaurants and shops scale back or close for the month, with most reopening by mid-October.

Forum posters describe late March as comfortable enough that a jacket isn't needed, though a light sweater or long-sleeve shirt is handy for breezy evenings. One temperature caveat worth knowing: the sea itself is only around 80F (about 26-27C) this early in the year, which posters are quick to note is not actually warm despite sounding pleasant on paper. For Road Town specifically, posters call it walkable from the cruise dock and fine for a shopping stop, but are candid it lacks major historical sights or standout beaches of its own - a $60 round-trip taxi is the going rate to reach the island's more scenic spots for a proper day out.
