Climate - Grenada

The climate of Grenada is tropical, hot and humid all year round, with a relatively cool season from December to March and a hot, sultry and rainy season from June to November.
The trade winds blow all year round, reducing the sensation of heat, usually from the north-east, although in the hot period they can blow from the east or the south-east.
Grenada is a country of the Lesser Antilles, which includes the main island, located at 12 degrees north latitude (therefore, halfway between the Equator and the Tropic of Cancer), plus the smaller southern Grenadines, located to the north.



Here are the average temperatures at Maurice Bishop International Airport in Point Salines, located south of the capital, St. George's. As you can see, there is little variation throughout the year.

Rainfall is abundant: in St. George's, on the south-western coast, almost 2,000 millimeters (78 inches) of rain fall per year, of which more than 100 mm (4 in) fall per month from May to January, and more than 200 mm (8 in) from June to November. The least rainy months are March and April, with 65/70 mm (2.6/2.8 in) per month on average.
Here is the average precipitation in George's.

In the southern Grenadines, administered by Grenada (Carriacou and Petite Martinique, plus some uninhabited islands), the rainfall pattern is similar, though they are a bit drier, in fact, they receive less than 1,500 mm (60 in) of rain per year. In Point Salines, in the southwestern tip of the main island, where the aforementioned airport is located, being that it's a flat area and away from inland elevations, precipitation drops below 1,500 mm (60 in) per year as well.



The interior of the main island is occupied by hills and low mountains, whose highest point is St. Catherine volcano, 840 meters (2,760 feet) high, where a rainforest grows, and we can speak of equatorial climate: precipitation is abundant throughout the year, reaching up to 3,500 mm (138 in) per year, the sky is often cloudy, and the temperature is a bit lower.
The rains in Grenada and the Grenadines usually occur throughout the year in the form of downpours or thunderstorms, which could be intense, but generally do not last long, so they do not reduce too much the sunshine hours; sometimes, however, there may be a more intense wave of bad weather.
In fact, the amount of sunshine is good all year round, at least on the coast, as can be seen in the following table.

The sea in Grenada is warm enough to swim in throughout the year: the water temperature ranges from 27 °C (81 °F) in the January-April period to 29 °C (84 °F) in September and October, as we can see in the following table.

Hurricanes

---

The greatest danger comes from tropical storms and cyclones, called hurricanes in the Caribbean area, which may pass over the area from June to November, though they are most likely from August to October. Grenada is located in the southernmost part of the hurricane belt, so it is rarely affected by them, although it may sometimes be affected, as happened with the following hurricanes: Hazel in October 1954, Janet in late September 1955, Joan in October 1988, Ivan in September 2004, and Felix in early September 2007.
