San Diego's climate in the 2050s

2041-2060 compared with 1991-2020, moderate emissions

By the 2050s, San Diego's climate will still be more like its own today than any other large city's. The nearest other is Long Beach (United States of America).

Climate risk in Long Beach

+1.5°C

Mean temperature over the year

+1.6°C

Highest in the warmest month

+1.3°C

Lowest in the coldest month

-3%

Precipitation over the year

Under high emissions, San Diego would stay nearest its own climate today.

Its own climate today is 1.7 σ away. How close the match is: 2.3 σ to the climate of Long Beach 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.

Drought risk Low-Medium Among large cities: above 1% In United States of America: 17 of 48
Earthquake shaking, once in 475 years 3.01 m/s² Among large cities: above 89% In United States of America: 9 of 51
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 San Diego on the live map
