Climate of Saint Vincent and the Grenadines
Country climate guideSaint Vincent and the Grenadines is a small Caribbean state of some 390 square kilometres, made up of the elongated island of Saint Vincent in the north and about two dozen smaller islands, cays and reefs running south toward Carriacou. It lies at about 13°N in the northern Lesser Antilles, and the main island is volcanic, rising from steep coastal cliffs to Mount Soufrière, a stratovolcano of about 1,234 metres. There are no large cities; a population of about 100,000 lives in small coastal villages and the capital, Kingstown.
Main climate types
Everything falls into the tropical group, with the humid rainforest subtype covering the interior and windward slopes of Saint Vincent and the drier savanna variant on the leeward south. The Grenadines, low and narrow with little relief, are warmer and drier. North-east trade winds blow through most of the year, and the whole group sits in the path of the Atlantic hurricane season.
Temperatures
Conditions stay warm all year. Along the coast, mean temperatures sit near 26 °C to 27 °C in almost every month, and the difference between the coldest and warmest month is only a degree or two. Highs are usually 29 °C to 31 °C and nights rarely fall below 20 °C, except on the highest ground, where the upper slopes of Mount Soufrière sit in cloud and are several degrees cooler.
Rainfall
Rain is heavy and driven by relief: the eastern, windward slopes of Saint Vincent can exceed 3,000 mm a year, while Kingstown on the leeward south-west coast receives about 1,600 mm to 2,000 mm and the Grenadines about 1,000 mm. The wettest months are usually May to June and September to November, and rain comes in intense squalls rather than all-day drizzle. January to April is the drier period.
When to go
Sailing and diving are best in the dry, breezy months from January to April, when the trades are steady and humidity lower. The rest of the year brings more rain and cloud. The group lies in the Atlantic hurricane belt, and storms between June and November occasionally pass over or near the islands.
