Tsunamis and landslides are not rated for a single city here. Climate risk profile of China
Hangzhou had 58 days over 35 °C in 2025.
Shanghai: 16 days.
Hangzhou's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, Hangzhou is projected to have the climate that Hengyang (China) has today.
+1.7°C
Mean temperature over the year
+1.7°C
Highest in the warmest month
+1.7°C
Lowest in the coldest month
+2%
Precipitation over the year
Under high emissions, Hangzhou would have the climate that Shangrao (China) has today.

How close the match is: 0.1 σ to the climate of Hengyang today, where under 2 is close and over 4 is no match (Mahony et al. 2017). 1 of 3 climate model runs name the same city. Seasonal temperature and rain are compared, not extremes, city heat or the sea.
Where else Hangzhou stands out

Hottest day of 2025
Shanghai: 37°C.
Higher than in 78% of the world's 630 large cities
17 days
Days with 20 mm of rain or more in 2025
Shanghai: 12 days.

| Water stress | Extremely High (>80%) | Among large cities: above 70% | In China: 1 of 135 |
| Drought risk | High | Among large cities: above 50% | In China: 1 of 135 |
| Earthquake shaking, once in 475 years | 0.24 m/s² | Among large cities: above 24% | In China: 102 of 135 |
| Land burned in an average year | 0% | ||
| Cyclone wind, once in 100 years | 34.14 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 Hangzhou on the live map
