Climate risk in Busan
Busan, South Korea · 3.5M people in the urban area
What threatens Busan most
- Cyclone wind
- Category 2 once in 100 years IRIS
- Earthquake
- Low GSHAP
Tsunamis and landslides are not rated for a single city here. Climate risk profile of South Korea
Busan had 17 days with 20 mm of rain or more in 2025.
Seoul: 21 days.
Busan's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, Busan is projected to have the climate that Xinyang (China) has today.
+1.6°C
Mean temperature over the year
+1.6°C
Highest in the warmest month
+1.4°C
Lowest in the coldest month
+3%
Precipitation over the year
Under high emissions, Busan would have the climate that Nanjing (China) has today.

How close the match is: 0.1 σ to the climate of Xinyang 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 Busan
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.
| Hazard | Busan | Among large cities | In South Korea |
|---|---|---|---|
| Hot days in 2025, over 35 °C | 0 days | ||
| Tropical nights in 2025, over 20 °C | 122 days | Among large cities: above 58% | In South Korea: 1 of 9 |
| Hottest day of 2025 | 29.2°C | Among large cities: above 4% | In South Korea: 9 of 9 |
| Warming by 2050, moderate emissions | +2.3°C | Among large cities: above 73% | In South Korea: 9 of 9 |
| Days with 20 mm of rain or more in 2025 | 17 days | Among large cities: above 77% | In South Korea: 5 of 9 |
| River flood depth, 100-year event | Dry at the city centre point | ||
| Coastal flood depth, 100-year event | Dry at the city centre point | ||
| Sea level rise by 2050, moderate emissions | 184 mm | Among large cities: above 14% | In South Korea: 3 of 5 |
| Earthquake shaking, once in 475 years | 0.37 m/s² | Among large cities: above 37% | In South Korea: 3 of 9 |
| Land burned in an average year | 0% | ||
| Cyclone wind, once in 100 years | 46.34 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 Busan on the live map
