Tsunamis and landslides are not rated for a single city here. Climate risk profile of South Korea
Daejeon had 19 days with 20 mm of rain or more in 2025.
Seoul: 21 days.
Daejeon's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, Daejeon is projected to have the climate that Gwangju (South Korea) has today.
+1.7°C
Mean temperature over the year
+1.7°C
Highest in the warmest month
+1.5°C
Lowest in the coldest month
+4%
Precipitation over the year
Under high emissions, Daejeon would have the climate that Gwangju (South Korea) has today.

How close the match is: 0.6 σ to the climate of Gwangju 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 Daejeon stands out
+2.4°C
Warming by 2050, moderate emissions
Seoul: +2.8°C.

Hazards at Daejeon
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 | Daejeon | Among large cities | In South Korea |
|---|---|---|---|
| Hot days in 2025, over 35 °C | 5 days | Among large cities: above 51% | In South Korea: 6 of 9 |
| Tropical nights in 2025, over 20 °C | 85 days | Among large cities: above 43% | In South Korea: 8 of 9 |
| Hottest day of 2025 | 36°C | Among large cities: above 48% | In South Korea: 6 of 9 |
| Warming by 2050, moderate emissions | +2.4°C | Among large cities: above 80% | In South Korea: 4 of 9 |
| Days with 20 mm of rain or more in 2025 | 19 days | Among large cities: above 82% | In South Korea: 3 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 | ||
| Water stress | High (40-80%) | Among large cities: above 56% | In South Korea: 1 of 8 |
| Drought risk | Medium-High | Among large cities: above 13% | In South Korea: 1 of 8 |
| Earthquake shaking, once in 475 years | 0.4 m/s² | Among large cities: above 39% | In South Korea: 2 of 9 |
| Land burned in an average year | 0% | ||
| Cyclone wind, once in 100 years | 40.25 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 Daejeon on the live map
