December to April is the best time for a St Vincent and the Grenadines yacht charter, and February to April is the strongest stretch within it: the driest months of the year, steady 15 to 20 knot trade winds, and the calmest conditions you will get in the Tobago Cays. But the honest answer is more interesting than “come in winter.” Every part of the calendar here has a real case, and because the SVG fleet is smaller than the BVI or Bahamas fleets, the month you pick decides how much choice you have as much as what the weather does.
The quick answer
- Best overall: February to April. Driest weather, settled 15 to 20 knot trades, and the Bequia Easter Regatta to close the season.
- Most festive: December and January. Christmas winds of 20 to 25 knots and sometimes stronger, full harbors, and the weeks that book out first.
- Quietest with the widest yacht choice: May and June. The trades ease to 10 to 20 knots from the southeast and the anchorages empty out.
- Green season, July to November: workable with honest planning. SVG sits at 13 degrees north, south of most storm traffic, but it is not risk-free and we plan those weeks flexibly.
- Whatever the month, book early. The fleet is small and many yachts position in from neighboring islands only when a charter is confirmed.
December and January: festive peak
December and January are the loudest, busiest, breeziest version of the Grenadines. The Christmas winds blow 20 to 25 knots from the northeast through December and January, with multi-day spells that run stronger, which makes for fast, lively sailing on the open channel crossings and a real point in favor of a catamaran if anyone in your group is new to boats.
This is also when demand peaks. Christmas and New Year weeks on the better crewed yachts are gone the earliest of any weeks in the year, and because the local fleet is small, there is no deep bench of last-minute alternatives. If the holidays are your window, we would start the search 9 to 12 months out. The reward is the Grenadines at their most social: Mustique over New Year is one of the Caribbean’s great people-watching anchorages, and the Blues Festival follows in late January.
February to April: the sweet spot
If you can travel in any month, we would point you at February, March, or April. These are the driest months of the year, the Christmas winds settle into steady 15 to 20 knot trades, and the swell in the channel crossings drops with them. The Tobago Cays are at their clearest and calmest, which matters because the snorkeling over the seagrass, with resident green turtles, is the single thing most of our clients remember from the week.
There are 2 events worth planning around. The Mustique Blues Festival runs late January into early February, and the Bequia Easter Regatta fills Admiralty Bay over Easter weekend. Both are worth building a charter around, and both mean booking that specific week early rather than assuming it will be open.
Broker insight
March is the month I would pick for a first Grenadines charter. The crossings between Bequia and Canouan are open Atlantic water, and in March you get them at 15 to 20 knots with the swell down, which is exactly the sailing people come here for. If you want Admiralty Bay quiet, take the front half of the month; by Easter week the regatta fills it.

May and June: the shoulder months
May and June are the months we recommend to clients who care more about empty anchorages than about the social calendar. The trades ease and swing southeast at 10 to 20 knots, the winter crowds are gone, and you get the widest choice of yachts and dates of any point in the year. The sailing is gentler, which suits families and first-timers, and the Tobago Cays on a June morning can feel close to private.
The tradeoff is honest but small: showers become more frequent than in the February to April window, though they pass quickly at this latitude. If your dates reach into late June, Vincy Mas, the national carnival, brings Kingstown to life into early July, and it is an easy add before or after the boat.
July to November: the honest version
Here is the part most charter sites skip. July to November is hurricane season across the Caribbean, and while SVG’s position at 13 degrees north puts it south of where most storms track, it is not outside the risk. Hurricane Beryl proved that on July 1, 2024, when it crossed the southern Grenadines as a Category 4 and hit Union Island hard. As of 2026 Union Island is open and rebuilt enough to welcome charter guests, and the Tobago Cays came through with their beauty intact, but we will not tell you the risk is zero, because it is not.
What we do about it is the useful part. We keep green season itineraries flexible, the captain and our team watch the forecasts daily, and the geography works in your favor: Grenada, the traditional southern refuge of the sailing world, is a short hop below the chain. October into early November is the wettest stretch, and we steer most clients away from those specific weeks. But July and August are genuinely charterable, and a lot of the Caribbean fleet spends its summer exactly here.
Broker insight
August in the Grenadines works better than most people expect. It is where a lot of the Caribbean fleet actually goes in summer, because the islands sit south of the worst of the storm traffic. We keep the itinerary flexible and watch the forecast daily with the captain, and in return you get the Tobago Cays with a fraction of the winter crowds.

How the season shapes yacht choice
The Grenadines are a sailing destination first, and the fleet reflects that: catamarans and sailing yachts dominate, with fewer large motor yachts based here year-round. In the windy December to January window, we shortlist catamarans for most groups because the beam keeps the boat flat and comfortable when the channels are blowing 25 knots. From February onward, monohull sailors get the conditions they dream about, and by May the gentler southeast trades open the shortlist right up.
The fleet’s size is the other seasonal factor. Many of the yachts we book position in from Grenada, St Lucia, or Martinique, so peak weeks book out first and the best boats go months ahead. One more thing that surprises new clients: the whole country runs on quieter-water rules, including a nationwide jet ski ban and tender restrictions inside the Tobago Cays Marine Park, which we cover in our guide to the jet ski ban. It is a big part of why the anchorages stay so peaceful.
Our recommendation
Book February to April if you want the Grenadines at their best, December to January if the holidays and the atmosphere are the point, and May to June if you want the islands quiet and the widest pick of the fleet. For green season, talk to us before you write it off; with a flexible plan and the right week, August here works better than most people expect.
Tell us your month and how your group likes to travel, and we will send you a shortlist of yachts that fit it. On a fleet this size, starting early is the single best move you can make.
People also ask
Which month is best for a St Vincent and the Grenadines yacht charter?
March is the best single month for most of our clients. It sits in the driest stretch of the year, the trades settle to 15 to 20 knots, and the channel crossings are at their most comfortable. February and April are nearly as good, with the Mustique Blues Festival and the Bequia Easter Regatta bookending the window.
When is a Grenadines yacht charter the best value?
May and June give you the most for your week. You get the widest choice of yachts and dates of the whole year, near-empty anchorages, and gentler 10 to 20 knot southeast trades that suit families and first-time sailors. The tradeoff is more frequent passing showers than in the February to April window.
Is it safe to charter in the Grenadines during hurricane season?
It can be, with honest planning. SVG sits at 13 degrees north, south of where most storms track, but it is not risk-free: Hurricane Beryl hit Union Island as a Category 4 in July 2024, and the island has since reopened to guests. For July and August charters we keep itineraries flexible, watch forecasts daily with the captain, and have Grenada a short hop south, which is why a lot of the Caribbean fleet spends its summer here.
How strong are the winds for sailing in the Grenadines?
Expect 20 to 25 knots from the northeast in December and January, with spells beyond that when the Christmas winds peak. From February through April the trades settle to a steady 15 to 20 knots, and by late spring and summer they ease to 10 to 20 knots from the southeast. The windier months favor catamarans for comfort; from February onward the conditions suit every yacht type in the fleet.
