Climate zones in East Timor, 1991 to 2020
Share of East Timor's classified land in each Köppen-Geiger zone in 1991 to 2020. Zones under 0.05% are left out. The 17,608 map cells used cover 99% of the country's outline (about 14,940 km²).
By major group: A (tropical) 95%, C (temperate) 4.7%.
Almost all of East Timor is one climate: Aw, tropical savannah, which covers 92% 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), 6.1% 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 East Timor'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) | 2.1% | 0.6% | Am +1.3 percentage points | Aw -1.9 percentage points |
| 2071 to 2099, SSP1-2.6 (low emissions) | 5.1% | 1.5% | Aw +5.1 percentage points | Am -3.6 percentage points |
| 2071 to 2099, SSP2-4.5 (middle of the road) | 6.1% | 2.5% | Aw +6 percentage points | Am -3.5 percentage points |
| 2071 to 2099, SSP5-8.5 (high emissions) | 6.8% | 3.3% | Aw +6.4 percentage points | Cwb -3.3 percentage points |
For the past row, the comparison runs the other way: the 1901 to 1930 map against 1991 to 2020.
