Oslo, Norway · 1.1M people in the urban area
What threatens Oslo most
- Water stress
- Low-Medium WRI Aqueduct
- Drought
- Low-Medium WRI Aqueduct
- River flood
- 0.28 m in a 100-year flood
Tsunamis and landslides are not rated for a single city here. Climate risk profile of Norway
A 100-year river flood would stand 0.28 m deep in the centre of Oslo.
Stockholm: Dry at the city centre point.
Oslo's climate in the 2050s
2041-2060 compared with 1991-2020, moderate emissions
By the 2050s, Oslo's climate will still be more like its own today than any other large city's. The nearest other is Gdansk (Poland).
+1.7°C
Mean temperature over the year
+1.9°C
Highest in the warmest month
+2°C
Lowest in the coldest month
+5%
Precipitation over the year
Under high emissions, Oslo would have the climate that Hamburg (Germany) has today.
Its own climate today is 0.1 σ away. How close the match is: 0.1 σ to the climate of Gdansk 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 Oslo
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 | Oslo | Among large cities | In Norway |
|---|---|---|---|
| Hot days in 2025, over 35 °C | 0 days | ||
| Tropical nights in 2025, over 20 °C | 0 days | ||
| Hottest day of 2025 | 30.3°C | Among large cities: above 8% | |
| Warming by 2050, moderate emissions | +2.1°C | Among large cities: above 60% | |
| Days with 20 mm of rain or more in 2025 | 8 days | Among large cities: above 45% | |
| River flood depth, 100-year event | 0.28 m | Among large cities: above 90% | |
| Coastal flood depth, 100-year event | Dry at the city centre point | ||
| Water stress | Low-Medium (10-20%) | Among large cities: above 30% | |
| Drought risk | Low-Medium | Among large cities: above 1% | |
| Earthquake shaking, once in 475 years | 0.29 m/s² | Among large cities: above 30% | |
| 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 Oslo on the live map
