How close the match is: 0.5 σ to the climate of Tunis 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.
Hazards at Algiers
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.

| Water stress | Extremely High (>80%) | Among large cities: above 70% | |
| Drought risk | High | Among large cities: above 50% | |

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 Algiers on the live map
