Tropical Climate: Trinidad and Tobago has a tropical climate, characterized by high temperatures and humidity all year round. The mean annual temperature ranges between 24-27 °C (75-81 °F).
Low Altitudes: Trinidad and Tobago consists mainly of low-lying plains and gently rolling hills. The highest point is El Cerro del Aripo at 940 meters (3,084 ft) above sea level. The low altitudes contribute to the accumulation of heat near the surface.
Lack of Significant Elevation Changes: The absence of significant elevation changes means that there is little variation in temperature and climate across the islands.
Trade Winds and Ocean Currents: Trinidad and Tobago is influenced by the warm Caribbean Sea and Atlantic Ocean. The trade winds, which are prevailing easterly winds, carry warm and humid air from the ocean onto the islands, contributing to the high temperatures.
Urbanization: Urban areas in Trinidad and Tobago, such as Port of Spain and San Fernando, experience the urban heat island effect. This phenomenon occurs when cities absorb and release heat from buildings, roads, and other infrastructure, leading to higher temperatures compared to rural areas.
Deforestation: The clearance of forests for agricultural purposes and urbanization reduces the amount of vegetation that can help regulate the microclimate. Deforestation can contribute to higher temperatures in affected areas.
Climate Change: Trinidad and Tobago is experiencing the effects of global climate change, which includes rising global temperatures. Increasing levels of greenhouse gases in the atmosphere trap heat and contribute to overall warming, exacerbating the heat conditions already experienced in the country.
