Climate zones in Equatorial Guinea, 1991 to 2020
Share of Equatorial Guinea's classified land in each Köppen-Geiger zone in 1991 to 2020. Zones under 0.05% are left out. The 31,040 map cells used cover 99% of the country's outline (about 26,639 km²).
By major group: A (tropical) 99%, C (temperate) 1%.
Am, tropical monsoon, is the main climate of Equatorial Guinea, covering 84% of its classified land in 1991 to 2020, with Af (tropical rainforest) next at 8.2%. 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), 6.6% 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 Equatorial Guinea'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) | 13% | 0.1% | Aw +3.5 percentage points | Am -6.7 percentage points |
| 2071 to 2099, SSP1-2.6 (low emissions) | 5.7% | 0.3% | Am +2 percentage points | Aw -2.9 percentage points |
| 2071 to 2099, SSP2-4.5 (middle of the road) | 6.6% | 0.5% | Am +2.6 percentage points | Aw -3.4 percentage points |
| 2071 to 2099, SSP5-8.5 (high emissions) | 6.6% | 0.8% | Af +2.1 percentage points | Aw -3.3 percentage points |
For the past row, the comparison runs the other way: the 1901 to 1930 map against 1991 to 2020.
