Climate of Trinidad and Tobago
Country climate guideTrinidad and Tobago is a two-island Caribbean state just off the north coast of South America, only about 11 degrees north of the equator, so its climate is one of almost constant warmth. Port of Spain, the capital, averages about 26 °C in January and around 27 °C in July, with annual rainfall of roughly 1,700 to 2,000 millimetres. Because the islands lie close to the mainland, weather systems can develop quickly.
Main climate types
Both islands are classified as a tropical rainforest or monsoon climate. Trinidad is drier than it looks: the northern hills and the north-west peninsula, exposed to the trade wind, receive up to 2,500 millimetres, while the south around Princes Town, in the rain shadow, gets only about 900 to 1,000. Tobago is wetter on its exposed north-east coast and drier and sunnier in the sheltered south-west, where most hotels lie.
Temperatures
Monthly means vary by only a degree or two across the year, typically between about 25 °C and 28 °C on both islands. January and February are coolest and June to September warmest. Inland, away from the sea, days are a few degrees warmer and nights a few degrees cooler. There is no cold season, no snow and no frost anywhere in the country, even on the highest hills.
Rainfall
Most rain falls between June and December, leaving January to May much drier. About two thirds of the annual total arrives in the wetter half of the year. Shower activity usually starts in the morning and clears by early afternoon, but heavy sustained rain is common in the mountains. Humidity is high all year and the sea never drops below about 25 °C, so swimming is possible every month.
When to go
The dry season, January to May, is the most comfortable for beaches, diving and hiking, with steady trade winds and lower humidity. Carnival, in the weeks before Ash Wednesday, brings the busiest and most expensive period of the year. Between June and December the chance of heavy rain and of tropical storms rises sharply; the peak of the hurricane season is September, so insurance covering storm disruption is advisable.
