Kingstown & Leeward Coast (southwest St. Vincent)
May carries the onset of more frequent tropical downpours inland, and the coast sees an uptick of short, intense showers and afternoon cloud buildups. Boating remains possible on good days but smaller ferries can be canceled with little notice during squalls; pack waterproofs and flexible plans. On the bright side, beaches still get long sunny stretches between showers and the island’s plant life goes lush after the rains.
Windward Highlands & La Soufrière (interior highlands)
June increases the frequency of heavy rain in the mountains; trail surfaces turn to sticky clay and even short hikes can become long affairs when footing is poor. The highlands receive some of the island’s highest monthly totals, fed by orographic lift off the slopes, and evening fogs are common. If you still want to hike, choose local guides who read weather patterns; rivers and trails can change rapidly after storms.
Northern Grenadines (Bequia, Admiralty Bay & surroundings)
June raises the risk of prolonged rainy spells and the start of hurricane season adds an element of unpredictability for mariners; local boat operators become more cautious with cross-island trips. When the weather is calm, however, Bequia still offers excellent snorkeling and quieter beaches as peak crowds thin. Always check local marine weather and have contingency plans for ferry returns.
Central Grenadines (Mustique, Canouan, Mayreau, Tobago Cays)
June marks the start of hurricane season, and although many days can be calm, the chance of tropical disturbances rises; must-book captains will monitor weather closely and may advise skipping certain passages. The marine park’s coral life is still vibrant, but storms create runoff and can reduce visibility near St. Vincent’s outlets. Purchase flexible tickets and consider lodging options with storm-cancellation policies.
Southern Grenadines & Union Island (Clifton, Tobago Cays approaches)
June introduces the hurricane season and with it a higher chance of unsettled passages between islands; captains become more conservative and some operators cut schedules. Visibility for dives can diminish after heavy rains, although the southern reefs are often less affected than the mainland’s coast. If you choose to visit now, opt for operators who track forecasts and provide firm cancellation terms.
