Kingstown & Leeward Coast (southwest St. Vincent)

April along the leeward shoreline starts to see the first hints of the wet season: sudden, heavy showers may interrupt sunbathing and create slick streets in Kingstown, but they usually pass quickly. Temperatures climb and the sea stays warm; this is the shoulder season for cheaper fares before the big summer rains, making it attractive to budget-minded travelers. Keep an eye on ferry schedules as a few services begin to reduce frequency when the winds pick up.

Windward Highlands & La Soufrière (interior highlands)

May marks the true start of the wet period in the highlands: persistent, hard showers are common and low clouds linger much of the day, especially around Richmond Peak and the volcano’s flanks. Trekking windows shrink and river levels become unpredictable, so local guides may alter or cancel summit attempts. Expect fewer tourists and lush jungle scenery - pack waterproof gear, insect repellent and plan flexible itineraries.

Northern Grenadines (Bequia, Admiralty Bay & surroundings)

May marks a wetter turn - short, intense squalls arrive more often and northeasterly swells occasionally make approach into Admiralty Bay bumpier. The landscape becomes greener and many small inland tracks show runoff, but the sheltered bays remain popular for anchoring between showers. If you’re planning sea trips, be prepared for some cancellations and take a flexible itinerary.

Central Grenadines (Mustique, Canouan, Mayreau, Tobago Cays)

May brings increased humidity and more frequent showers, particularly in the afternoons, and the sea can cloud after downpours; currents around the Cays can pick up. Some charter fleets start to thin as hurricane season approaches, translating into slightly lower rates but reduced availability for specialized trips. Pack waterproof dry bags for camera gear and expect to adapt plans around weather windows.

Southern Grenadines & Union Island (Clifton, Tobago Cays approaches)

May tends to bring more frequent downpours and a perceptible jump in humidity, and small boat services can be canceled at short notice when squalls move through the archipelago. When skies clear there are still fantastic snorkeling windows, but post-rain runoff can reduce clarity near island mouths. Travelers should keep flexible plans and waterproof luggage in case crossings are postponed.
