The best time to sail the Grenadines: winds, weather & season guide
If you're planning a Grenadines sailing holiday, the season you pick shapes almost everything — how much wind you'll carry, how busy the anchorages will be, and how much you'll pay. Here's how we think about it after twenty-plus seasons on the water in St Vincent & The Grenadines.
The dry season: December to May. This is the classic Caribbean sailing window. Trade winds blow steadily from the east-northeast, humidity drops, showers are brief and passing, and the sea state settles into the long, ordered swell that makes reaching between the islands so enjoyable. Sea temperature holds around 27°C the whole way through.
The Christmas Winds: mid-December to late February. The strongest and most reliable trades of the year — commonly 18 to 25 knots, occasionally more. Big-catamaran passages between Bequia, Mustique and the Tobago Cays are fast and exhilarating. It's also the peak booking season: Christmas, New Year and February half-term book out six to nine months ahead, and rates are at their highest.
March to May: the shoulder-of-peak sweet spot. In our view this is the best all-round window. The Christmas rush is over, winds ease to a comfortable 15–18 knots, mornings are calm enough for paddleboards and drone flights, and the islands feel unhurried. Water clarity in the Tobago Cays is often at its best.
June and early July: the value shoulder season. Winds soften to 10–15 knots, showers pick up but rarely last, and rates drop meaningfully. Hurricane season officially opens on 1 June, but the historical track record shows very few storms reaching the southern Caribbean before August — this is a genuinely good time to sail if you're flexible.
Late July through October: low season. Warmer, wetter, and lighter winds mean this window is best avoided for a first-time charter. Most of our fleet is hauled out for annual refit during September and October.
November: the season restarts. Trades rebuild through the month, the islands come alive again for the new season, and rates are still shoulder-priced. A quietly excellent time to visit if you want the December weather without the December crowds.
Practical advice. For steady reaching and predictable weather, aim for late January through April. For big-breeze passage-making, go over Christmas and book early. For value and quiet anchorages, look at June or November. Whatever you choose, we'll match the yacht and itinerary to the conditions you'll actually meet — get in touch and we'll plan it with you.
