St. Vincent and the Grenadines Climate Guide

Climate Overview

St. Vincent and the Grenadines has a tropical maritime climate with two distinct seasons. The drier season runs from January through May, with February and March being the driest months when rainfall drops below 100 mm3.9 in per month. The wet season extends from June through December, driven by the Inter-Tropical Convergence Zone, with peak rainfall from July to October when monthly totals regularly exceed 200 mm7.9 in.

Annual rainfall at the coast around Kingstown averages approximately 2,000 mm79 in, while the mountainous interior of St. Vincent receives up to 3,800 mm150 in. The low-lying Grenadines are notably drier, receiving less than 1,500 mm59 in per year.

Temperatures are stable year-round, with daytime highs along the coast ranging from 29 °C84 °F in winter to 31 °C88 °F in summer, and overnight lows between 24 °C75 °F and 26 °C79 °F. Northeast trade winds blow steadily throughout the year, moderating the tropical heat and providing natural cooling at the coast.

The trades are most consistent during the drier season and become more variable during the wet months. Humidity remains high, typically between 75% and 85%, though the trade winds keep coastal conditions comfortable.

Hurricane History

St. Vincent and the Grenadines lies in the Windward Islands at latitude 13°N, within the path of Cape Verde-type hurricanes entering the Caribbean.

The 1898 Windward Islands Hurricane struck on September 11, passing directly over Kingstown at approximately local noon. Based on a barometric pressure reading of 965 mbar at the Botanic Gardens, the Atlantic hurricane reanalysis project estimated sustained winds of 175 km/h110 mph, equivalent to a Category 2 hurricane. The storm killed approximately 300 people on St. Vincent, destroyed or severely damaged around 6,000 homes, and displaced roughly 20,000 people.

Hurricane Janet (September 22, 1955) passed through the Grenadines with sustained winds of 170 km/h105 mph, killing 122 people across the Grenadines and causing widespread destruction that led to the passage of the 1955 Housing Act and the creation of the National Housing Authority.

Hurricane Tomas (October 30, 2010) skirted the northern coast of St. Vincent as a Category 1 hurricane, destroying 98% of the banana crop in the affected areas and damaging approximately 1,200 homes. Agricultural losses alone were estimated at US$25 million.

Most recently, Hurricane Beryl (July 1, 2024, Category 4) struck the southern Grenadines with sustained winds of 240 km/h150 mph. The earliest Category 4 hurricane on record in the Atlantic, Beryl damaged or destroyed 90% of structures on Union Island and caused an estimated US$231 million in damage across the country, representing roughly 22% of GDP.

Geography & Terrain

St. Vincent and the Grenadines is an island nation in the Windward Islands of the Lesser Antilles, located approximately 100 km62 miles south of Saint Lucia and 135 km84 miles north of Grenada. The country covers a total area of 389 km²150 sq mi and consists of the main island of St. Vincent (344 km²133 sq mi) and a chain of 32 smaller islands and cays in the Grenadines stretching approximately 75 km47 miles to the south.

St. Vincent itself is roughly 29 km18 miles long and 18 km11 miles wide, with a mountainous volcanic spine running north to south. La Soufriere, an active stratovolcano at the northern end of the island, is the highest point at 1,234 m4,049 ft. The inhabited Grenadines, including Bequia, Mustique, Canouan, Mayreau, and Union Island, are low-lying coral and volcanic islands with drier climates than the main island.

La Soufriere has erupted multiple times in recorded history and profoundly shapes life on the island. The catastrophic eruption of May 7, 1902 sent pyroclastic flows down all flanks of the volcano, killing approximately 1,600 people. This occurred just one day before the eruption of Mount Pelee in Martinique.

More recently, La Soufriere erupted explosively on April 9, 2021, sending ash plumes to 8,000 m26,248 ft and triggering the evacuation of over 20,000 residents from the northern red zone. No lives were lost in the 2021 eruption, though agricultural land and infrastructure in the north suffered heavy damage.

The volcanic terrain strongly influences weather patterns across St. Vincent. Northeast trade winds carry moisture-laden air from the Atlantic that is forced upward by the mountainous interior, producing heavy orographic rainfall on the windward slopes that can be more than double the coastal totals. The leeward western coast sits in a partial rain shadow.

The island's rich volcanic soils and abundant rainfall sustain dense tropical rainforest across the interior highlands, while the Grenadines are characterized by drier scrubland and coral reef ecosystems.
