Dublin in 2050: climate change in numbers
Dublin has warmed 1.0 °C, comparing the last ten years (2016–2025) with 1951–1980 — about as fast as the world as a whole (+1.1 °C). By 2050, it is heading for a climate that no large city has today.
2050 = 2040–2059 average, intermediate emissions (SSP2-4.5), median of CMIP6 climate models. “Today” = 1991–2020. Model range for average temperature: 9.9–11.3 °C.

What Dublin's climate will feel like
We compared Dublin's projected 2050 climate with today's climate in more than 1,000 large cities. None is a close match; the nearest is Bogotá, Colombia. Scientists call this a novel climate: conditions the city's people, buildings and infrastructure have no local experience of.

What changes by 2050
- The average temperature rises a further 1.1 °C compared with 1991–2020 (model range 0.2–1.6 °C).
Dangerous heat in Dublin
Even by 2090 under very high emissions, Dublin 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 Dublin
The sea at Dublin is projected to rise about 21 cm by 2050 and 52 cm by 2100 (IPCC AR6, intermediate emissions). See the full sea level projection for Dublin.
Under high emissions
If emissions keep rising (SSP5-8.5), Dublin would average 10.9 °C by 2040–2059, with a hottest day around 25 °C. 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 Dublin be in 2050?
Under an intermediate emissions scenario (SSP2-4.5), Dublin's average annual temperature in 2040–2059 is projected at about 10.8 °C (range 9.9–11.3 °C across climate models), compared with 9.7 °C in 1991–2020. The hottest day of a typical year reaches about 24 °C (76 °F).
Is Dublin getting hotter?
Yes. The last ten years (2016–2025) averaged 1.0 °C warmer than 1951–1980 in Dublin, about as fast as the global average of 1.1 °C over the same period (Copernicus ERA5).
Which city will Dublin feel like in 2050?
No large city today has a climate quite like Dublin's projected 2050 climate. The closest match is Bogotá, Colombia, but the fit is loose — Dublin is heading into a climate with no close equivalent among the world's large cities.
What would happen under high emissions?
Under a very high emissions scenario (SSP5-8.5), Dublin's average temperature in 2040–2059 is projected at 10.9 °C and the hottest day at about 25 °C. The differences between scenarios grow much larger after 2050.
