- 0.07 m in a 100-year flood
Tsunamis and landslides are not rated for a single city here. Climate risk profile of Belgium
A 100-year river flood would stand 0.07 m deep in the centre of Brussels.
Lille: Dry at the city centre point.
Brussels's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, Brussels is projected to have the climate that Paris (France) has today.
+1.3°C
Mean temperature over the year
+2°C
Highest in the warmest month
+1°C
Lowest in the coldest month
-2%
Precipitation over the year
Under high emissions, Brussels would have the climate that Paris (France) has today.
Share this comparison
How close the match is: 0.1 σ to the climate of Paris today, where under 2 is close and over 4 is no match (Mahony et al. 2017). 1 of 3 climate model runs name the same city. Seasonal temperature and rain are compared, not extremes, city heat or the sea.
Hazards at Brussels
Read at the city's centre and compared with the Atlas's 630 large cities. Moderate emissions is the IPCC's scenario SSP2-4.5.
| Hazard | Brussels | Among large cities | In Belgium |
|---|---|---|---|
| Hot days in 2025, over 35 °C | 1 day | Among large cities: above 38% | |
| Tropical nights in 2025, over 20 °C | 0 days | ||
| Hottest day of 2025 | 36°C | Among large cities: above 47% | |
| Warming by 2050, moderate emissions | +1.6°C | Among large cities: above 24% | |
| Days with 20 mm of rain or more in 2025 | 1 day | Among large cities: above 7% | |
| River flood depth, 100-year event | 0.07 m | Among large cities: above 86% | |
| Coastal flood depth, 100-year event | Dry at the city centre point | ||
| Water stress | Extremely High (>80%) | Among large cities: above 70% | |
| Drought risk | Medium-High | Among large cities: above 13% | |
| Earthquake shaking, once in 475 years | 0.66 m/s² | Among large cities: above 53% | |
| Land burned in an average year | 0% | ||
| Cyclone wind, once in 100 years | 0 m/s |
Flood depth is read in a single 1 km cell at the city's centre, in today's climate. Other parts of the city can still flood. The country page names the deepest point near a coastal city in 2080, so its figure can be higher. See how deep a river flood reaches around Brussels on the live map
