Climate zones in Honduras, 1991 to 2020
Share of Honduras's classified land in each Köppen-Geiger zone in 1991 to 2020. Zones under 0.05% are left out. The 134,924 map cells used cover 99% of the country's outline (about 111,992 km²).
By major group: A (tropical) 90%, C (temperate) 10%.
Honduras has no single dominant climate. The biggest zone, Aw (tropical savannah), covers only 49% of its classified land in 1991 to 2020, followed by Am (24%) and Af (17%). 6 zones each cover 1% or more of it. In plain terms, tropical savannah means hot all year, with a clear dry season. Under the middle-of-the-road scenario (SSP2-4.5), 20% 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 Honduras'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) | 28% | 5.5% | Aw +12.2 percentage points | Af -11 percentage points |
| 2071 to 2099, SSP1-2.6 (low emissions) | 14% | 4.5% | Aw +5.4 percentage points | Af -3.3 percentage points |
| 2071 to 2099, SSP2-4.5 (middle of the road) | 20% | 6.9% | Aw +9.8 percentage points | Af -5.8 percentage points |
| 2071 to 2099, SSP5-8.5 (high emissions) | 38% | 9.4% | Aw +20.5 percentage points | Af -15.5 percentage points |
For the past row, the comparison runs the other way: the 1901 to 1930 map against 1991 to 2020.
