How to read the map. Each colour is a Köppen-Geiger climate class. The first letter is the major group (A tropical, B arid, C temperate, D cold, E polar); the other letters say how dry it is and how warm or cold. Tap anywhere to see the class under that spot in 1901 to 1930, 1991 to 2020 and, under three emissions scenarios, 2071 to 2099. The codes and names are always given in words, because colour alone is hard to tell apart for some people.

Climate zones in Benin, 1991 to 2020

Share of Benin's classified land in each Köppen-Geiger zone in 1991 to 2020. Zones under 0.05% are left out. The 137,489 map cells used cover 100% of the country's outline (about 116,341 km²).

Aw Tropical savannah96%
BSh Hot semi-arid (steppe)4.2%

By major group: A (tropical) 96%, B (arid) 4.2%.

Almost all of Benin is one climate: Aw, tropical savannah, which covers 96% of its classified land in 1991 to 2020. In plain terms, tropical savannah means hot all year, with a clear dry season. Under the middle-of-the-road scenario (SSP2-4.5), almost none of Benin changes zone by 2071 to 2099 (0.6%).

How Benin'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.

For the past row, the comparison runs the other way: the 1901 to 1930 map against 1991 to 2020.
