San Salvador's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, San Salvador's climate will still be more like its own today than any other large city's. The nearest other is Goiânia (Brazil).

Under high emissions, no large city has such a climate today; the nearest is Mbuji-Mayi (Dem. Rep. Congo).
Its own climate today is 4.2 σ away. How close the match is: 5.3 σ to the climate of Goiânia today, where under 2 is close and over 4 is no match (Mahony et al. 2017). 3 of 3 climate model runs name the same city. Seasonal temperature and rain are compared, not extremes, city heat or the sea.

| River flood depth, 100-year event | Dry at the city centre point | ||
| Coastal flood depth, 100-year event | Dry at the city centre point | ||
| Water stress | Low-Medium (10-20%) | Among large cities: above 30% | |
| Drought risk | High | Among large cities: above 50% | |
| Earthquake shaking, once in 475 years | 3.36 m/s² | Among large cities: above 92% | |
| Land burned in an average year | 0% | ||
| Cyclone wind, once in 100 years | 28.21 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 San Salvador on the live map
