Hurricane History

Although Grenada sits near the southern edge of the Atlantic hurricane belt at latitude 12°N, it has suffered several devastating storms. Hurricane Janet (1955) struck on September 22 with 185 km/h115 mph sustained winds, killing 122 people across Grenada, Carriacou, and Petite Martinique, destroying 50% of the housing stock and 70% of the nutmeg trees.

Hurricane Ivan (2004, Category 3) passed just south of the island on September 7 with sustained winds of 195 km/h120 mph and gusts to 215 km/h133 mph. Ivan killed 39 people and damaged 90% of buildings, causing an estimated US$900 million in damage, roughly 200% of GDP. Less than a year after Ivan, Hurricane Emily (2005) struck Carriacou and the main island, damaging over 2,600 homes and causing US$45 million in additional losses while the country was still rebuilding.

Most recently, Hurricane Beryl (2024, Category 4) passed directly over Carriacou on July 1 with 240 km/h150 mph sustained winds. The earliest Category 4 hurricane on record in the Atlantic, Beryl damaged or destroyed 99% of structures on Carriacou and caused an estimated US$218 million in damage across the country.

Geography & Terrain

Grenada is the southernmost of the Windward Islands, located approximately 160 km100 miles north of Venezuela. The tri-island nation comprises the main island of Grenada, along with Carriacou and Petite Martinique in the southern Grenadines, covering a total area of 344 km²133 sq mi.

The main island is of volcanic origin with a rugged, mountainous interior rising to Mount Saint Catherine, a dormant stratovolcano and the country's highest point at 840 m2,757 ft. Volcanic craters filled with water form scenic features including Grand Etang Lake, situated at 530 m1,739 ft elevation within the Grand Etang National Park. The coastline features numerous bays and beaches, including the 3 km1.9 mile long Grand Anse Beach.

Grenada's mountainous terrain has a strong influence on local weather patterns. The northeast trade winds carry moisture-laden air from the Atlantic, which is forced upward by the volcanic peaks, producing heavy orographic rainfall in the interior that can be more than double the coastal totals. The leeward western coast receives less rainfall than the windward eastern slopes.

Known as the "Spice Island," Grenada's rich volcanic soils and abundant rainfall support lush tropical vegetation and the cultivation of nutmeg, of which Grenada is one of the world's largest producers. The submarine volcano Kick 'em Jenny, located 8 km5 miles north of the main island, is the most active volcano in the Lesser Antilles arc.
