Climate zones in Bosnia and Herzegovina, 1991 to 2020
Share of Bosnia and Herzegovina's classified land in each Köppen-Geiger zone in 1991 to 2020. Zones under 0.05% are left out. The 83,974 map cells used cover 100% of the country's outline (about 51,713 km²).
By major group: C (temperate) 58%, D (cold (continental)) 42%.
Bosnia and Herzegovina has no single dominant climate. The biggest zone, Dfb (warm-summer humid continental), covers only 40% of its classified land in 1991 to 2020, followed by Cfb (29%) and Cfa (27%). 5 zones each cover 1% or more of it. In plain terms, warm-summer humid continental means warm summers and cold, snowy winters, with rain all year. Under the middle-of-the-road scenario (SSP2-4.5), 57% of its land is projected to be in a different zone by 2071 to 2099, with the biggest gain going to Cfa (humid subtropical). The most common zone would then be Cfa (humid subtropical).
How Bosnia and Herzegovina'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) | 53% | 46% | Cfb +22.8 percentage points | Dfb -43.6 percentage points |
| 2071 to 2099, SSP1-2.6 (low emissions) | 47% | 18% | Cfa +30.3 percentage points | Dfb -16.8 percentage points |
| 2071 to 2099, SSP2-4.5 (middle of the road) | 57% | 25% | Cfa +45.1 percentage points | Dfb -23.9 percentage points |
| 2071 to 2099, SSP5-8.5 (high emissions) | 73% | 40% | Cfa +62 percentage points | Dfb -38.1 percentage points |
For the past row, the comparison runs the other way: the 1901 to 1930 map against 1991 to 2020.
