Copenhagen in 2050: climate change in numbers
Copenhagen has warmed 2.0 °C, comparing the last ten years (2016–2025) with 1951–1980 — faster than the world as a whole (+1.1 °C). By 2050, its climate is projected to feel like London, United Kingdom today.
2050 = 2040–2059 average, intermediate emissions (SSP2-4.5), median of CMIP6 climate models. “Today” = 1991–2020. Model range for average temperature: 9.3–11.0 °C.

What Copenhagen's climate will feel like
Matching temperature, heat extremes, frost days and rainfall against the current climate of more than 1,000 large cities, Copenhagen's 2050 climate is closest to London, United Kingdom — about 1,000 km away.
| Copenhagen today | Copenhagen 2050 | London today | |
|---|---|---|---|
| Average temperature | 8.8 °C | 9.9 °C | 10.7 °C |
| Average daily high | 11.7 °C | 12.8 °C | 14.0 °C |
| Hottest day | 28 °C | 30 °C | 30 °C |
| Frost days | 71 | 53 | 28 |
| Rainfall | 734 mm | 772 mm | 704 mm |

What changes by 2050
- The average temperature rises a further 1.1 °C compared with 1991–2020 (model range 0.4–2.2 °C).
- Frost days fall from about 71 to 53 a year: shorter, milder winters.
Dangerous heat in Copenhagen
Even by 2090 under very high emissions, Copenhagen is not projected to have days with a heat index of 39 °C or more in a typical year. See where dangerous heat spreads worldwide.
Sea level at Copenhagen
The sea at Copenhagen is projected to rise about 22 cm by 2050 and 52 cm by 2100 (IPCC AR6, intermediate emissions). See the full sea level projection for Copenhagen.
Under high emissions
If emissions keep rising (SSP5-8.5), Copenhagen would average 10.4 °C by 2040–2059, with a hottest day around 31 °C and 1 days above 30 °C (86 °F) a year. By mid-century the scenarios are still close; the choices made now mostly decide what happens after 2050 — see the world in 2050.

Frequently asked questions
How hot will Copenhagen be in 2050?
Under an intermediate emissions scenario (SSP2-4.5), Copenhagen's average annual temperature in 2040–2059 is projected at about 9.9 °C (range 9.3–11.0 °C across climate models), compared with 8.8 °C in 1991–2020. The hottest day of a typical year reaches about 30 °C (87 °F).
Is Copenhagen getting hotter?
Yes. The last ten years (2016–2025) averaged 2.0 °C warmer than 1951–1980 in Copenhagen, faster than the global average of 1.1 °C over the same period (Copernicus ERA5).
Which city will Copenhagen feel like in 2050?
By 2040–2059, Copenhagen's climate is projected to resemble the climate of London, United Kingdom today, based on temperature, heat extremes, frost and rainfall.
What would happen under high emissions?
Under a very high emissions scenario (SSP5-8.5), Copenhagen's average temperature in 2040–2059 is projected at 10.4 °C and the hottest day at about 31 °C. The differences between scenarios grow much larger after 2050.
