Climate zones in Cuba, 1991 to 2020
Share of Cuba's classified land in each Köppen-Geiger zone in 1991 to 2020. Zones under 0.05% are left out. The 135,583 map cells used cover 98% of the country's outline (about 108,213 km²).
By major group: A (tropical) 100%, C (temperate) 0.3%.
Aw, tropical savannah, is the main climate of Cuba, covering 81% of its classified land in 1991 to 2020, with Am (tropical monsoon) next at 15%. In plain terms, tropical savannah means hot all year, with a clear dry season. Under the middle-of-the-road scenario (SSP2-4.5), 8.7% of its land is projected to be in a different zone by 2071 to 2099, with the biggest gain going to Aw (tropical savannah).
How Cuba'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) | 9.2% | 0.3% | Am +4.4 percentage points | Aw -6.1 percentage points |
| 2071 to 2099, SSP1-2.6 (low emissions) | 7.3% | 0.1% | Aw +1.1 percentage points | Af -0.8 percentage points |
| 2071 to 2099, SSP2-4.5 (middle of the road) | 8.7% | 0.2% | Aw +4.1 percentage points | Am -2.9 percentage points |
| 2071 to 2099, SSP5-8.5 (high emissions) | 14% | 0.3% | Aw +9.7 percentage points | Am -7.3 percentage points |
For the past row, the comparison runs the other way: the 1901 to 1930 map against 1991 to 2020.
