Climate zones in Luxembourg, 1991 to 2020
Share of Luxembourg's classified land in each Köppen-Geiger zone in 1991 to 2020. Zones under 0.05% are left out. The 4,684 map cells used cover 100% of the country's outline (about 2,598 km²).
By major group: C (temperate) 100%.
Almost all of Luxembourg is one climate: Cfb, temperate oceanic, which covers 100% of its classified land in 1991 to 2020. In plain terms, temperate oceanic means mild and damp, with no extremes. Under the middle-of-the-road scenario (SSP2-4.5), 1.2% of its land is projected to be in a different zone by 2071 to 2099, with the biggest gain going to Cfa (humid subtropical).
How Luxembourg'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) | 12% | 12% | Cfb +11.7 percentage points | Dfb -11.7 percentage points |
| 2071 to 2099, SSP1-2.6 (low emissions) | 0% | 0% | No change | No change |
| 2071 to 2099, SSP2-4.5 (middle of the road) | 1.2% | 0% | Cfa +1.2 percentage points | Cfb -1.2 percentage points |
| 2071 to 2099, SSP5-8.5 (high emissions) | 95% | 0% | Cfa +94.6 percentage points | Cfb -94.6 percentage points |
For the past row, the comparison runs the other way: the 1901 to 1930 map against 1991 to 2020.

Percentages are of the country's classified land in each map. A dash means under 0.05%.
