Changsha had 62 days over 35 °C in 2025.
Shanghai: 16 days.
Changsha's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, Changsha is projected to have the climate that Hengyang (China) has today.
+1.7°C
Mean temperature over the year
+1.4°C
Highest in the warmest month
+1.8°C
Lowest in the coldest month
+2%
Precipitation over the year
Under high emissions, Changsha would have the climate that Ganzhou (China) has today.

How close the match is: 0.5 σ to the climate of Hengyang 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.
Where else Changsha stands out
40.4°C
Hottest day of 2025
Shanghai: 37°C.
Higher than in 80% of the world's 630 large cities
Hazards at Changsha
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 | High (40-80%) | Among large cities: above 56% | In China: 52 of 135 |
| Drought risk | Medium-High | Among large cities: above 13% | In China: 74 of 135 |
| Earthquake shaking, once in 475 years | 0.08 m/s² | Among large cities: above 8% | In China: 132 of 135 |

| Cyclone wind, once in 100 years | 20.13 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 Changsha on the live map
