Brazzaville's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, Brazzaville is projected to have a climate no large city has today. The nearest, Kumasi (Ghana), is far from it.
Such a climate exists today, though not in any large city. Thailand: the place on the map

| River flood depth, 100-year event | 3.21 m | Among large cities: above 99% | |
| Coastal flood depth, 100-year event | Dry at the city centre point | ||
| Water stress | Low (<10%) | Among large cities: above 0% | |
| Drought risk | Low-Medium | Among large cities: above 1% | |
| Earthquake shaking, once in 475 years | 0 m/s² | Among large cities: above 1% | |

| 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 Brazzaville on the live map
