You are here: Home --> Caribbean --> Trinidad and Tobago



The climate of Trinidad and Tobago is tropical. Temperatures vary little throughout the year, however, there is a relatively cooler period from December to February and a hot, muggy period from May to October. Luckily, the trade winds blow all year round, tempering the heat.
As for the rains, there is a rainy season, which runs from June to December, and a relatively dry season, which runs from February to mid-April.
The islands forming the archipelago of Trinidad and Tobago, namely the two main islands of the same name plus some smaller islands (including Little Tobago), are located just north-east of the coast of Venezuela, and are the southernmost of the Lesser Antilles, although some geographers do not consider them as part of the said Lesser Antilles because of their eccentric position, together with Barbados.

Scarborough, on the island of Tobago, receives 1,500 mm (60 in) of rain per year: here too, precipitation exceeds 100 mm (4 in) per month from June to December, but it exceeds 200 mm (8 in) only in October and November.
In the interior of both islands, there are some elevations: in Trinidad, they are found in the northern part, where there are two peaks reaching 1,000 meters (3,300 feet), El Cerro del Aripo and El Tucuche, while Tobago is crossed by a chain of hills and low mountains in the interior, reaching 640 meters (2,100 feet). On the slopes of both islands, the climate is even rainier, especially those facing north, where rainfall reaches as high as 3,800 mm (150 in) per year.
Since the rains occur throughout the year especially in the form of showers or thunderstorms, they do not reduce too much the amount of sunshine, which is good in all months, especially along the coast, as can be seen in the following table.

Hurricanes



Trinidad and Tobago is in theory just outside of the hurricane belt, and in fact it is seldom, if ever, affected, especially the island of Trinidad, which is even more sheltered because of its southern position. However, we recall that the hurricane season in the Caribbean goes from June to November, though they are more likely from August to October. Some hurricanes and tropical storms that hit the islands in the past were Hurricane 2 (or Trinidad Hurricane) of July 1933 (the only truly destructive one), Tropical Storm Alma in August 1974, Tropical Storm Bret in August 1993, Hurricane Ivan in September 2004, and Hurricane Felix in September 2007.
