Climate zones in Trinidad and Tobago, 1991 to 2020
Share of Trinidad and Tobago's classified land in each Köppen-Geiger zone in 1991 to 2020. Zones under 0.05% are left out. The 5,963 map cells used cover 98% of the country's outline (about 5,035 km²).
By major group: A (tropical) 100%.
Am, tropical monsoon, is the main climate of Trinidad and Tobago, covering 61% of its classified land in 1991 to 2020, with Af (tropical rainforest) next at 37%. In plain terms, tropical monsoon means hot all year, with a very wet season and a short dry spell. Under the middle-of-the-road scenario (SSP2-4.5), 40% of its land is projected to be in a different zone by 2071 to 2099, with the biggest gain going to Am (tropical monsoon).
How Trinidad and Tobago's zones have changed and may change
Each row compares a map with 1991 to 2020. "Share in a different zone" is the share of the country's area whose class is different from 1991 to 2020. Future rows are model projections under an emissions scenario, not forecasts.
| Map | Share in a different zone | Different major group | Biggest gain | Biggest loss |
|---|---|---|---|---|
| 1901 to 1930 (past) | 48% | 0% | Af +33.8 percentage points | Am -21.3 percentage points |
| 2071 to 2099, SSP1-2.6 (low emissions) | 13% | 0% | Am +4.6 percentage points | Af -7.8 percentage points |
| 2071 to 2099, SSP2-4.5 (middle of the road) | 40% | 0% | Am +20.6 percentage points | Af -30.2 percentage points |
| 2071 to 2099, SSP5-8.5 (high emissions) | 72% | 0% | Aw +35.7 percentage points | Af -36.9 percentage points |
For the past row, the comparison runs the other way: the 1901 to 1930 map against 1991 to 2020.
