The climate of Grenada: when to go to Grenada

The island of Grenada has a wet tropical climate with average annual temperatures of 28°C, the climate is often tempered by trade north-east winds. There are two seasons that characterize the climate of the island, the humid and hot rainy season between June and December and the dry season between January and May.

The average annual rainfall varies between 1,500-2,000 mm along the coasts and 3,800-5,000 mm in the mountainous interior areas. The months between June and November are also hurricane season. The island of Grenada, however, is at the southern end of the hurricane belt that is rarely hit by a hurricane.

The islands of Carriacou and Petit Martinique, which lie to the north-east of Grenada, receive much less rain than Grenada, mainly due to the small size of the islands and the low height of their mountains. The island of Carriacou, for example, receives 1,300 mm of rain annually.

The temperature of the sea on the island of Grenada and in the islands of the archipelago is great for swimming in the sea all year round, in fact it varies between 26 ° C in January and February and 28 ° C in the months between July and November.


The best months for a visit to the island of Grenada are the driest months between January and May.
