Explore historical and projected climate data, climate data by sector, impacts, key vulnerabilities and what adaptation measures are being taken. Explore the overview for a general context of how climate change is affecting Trinidad and Tobago.
This page presents high-level information for Trinidad and Tobago's climate zones and its seasonal cycle for mean temperature and precipitation for the latest climatology, 1991-2020. Climate zone classifications in the map below use observed, historical data (sourced from the Climate Research Unit [CRU]) and are derived by applying the Köppen-Geiger climate classification methodology. This classification divides climate into five primary climate groups, which are divided based on seasonal precipitation and temperature patterns. The five primary groups are A (tropical), B (dry), C (temperate), D (continental), and E (polar). All climates, except for those in the E group are assigned a seasonal precipitation sub-group (second letter). It is important to understand the different climate contexts that exist within a country as well as the surrounding region when analyzing current climates and projected change. Climate classifications are identified by hovering your mouse over the legend. A narrative overview of Trinidad and Tobago's country context and climate is provided following the visualizations.

The Republic of Trinidad and Tobago is an archipelagic state in the southern Caribbean, located between 10°N and 11.5°N latitude, and 60°W and 62°W longitude. The country lies northeast of Venezuela and south of Grenada in the Lesser Antilles. It shares maritime boundaries with Barbados to the northeast and Guyana to the southeast. The country covers an area of 5,131 km2 with the island of Trinidad being the larger and more populous of the two main islands. Tobago is much smaller, comprising about 6% of the total area and 4% of the population. The country’s population is approximately 1.4 million (2020) people. Its economy is mainly supported by oil and gas production. As a Small Island Developing State (SIDS), the country is vulnerable to temperature increases, changes in precipitation and sea level rise. Other vulnerabilities include increased flooding, increased frequency and intensity of hurricanes, hillside erosion and loss of coastal habitats.
