Denver in 2050: climate change in numbers
Denver has warmed 1.6 °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 Ankara, Turkey today.
2050 = 2040–2059 average, intermediate emissions (SSP2-4.5), median of CMIP6 climate models. “Today” = 1991–2020. Model range for average temperature: 10.4–11.8 °C.

What changes by 2050
- The average temperature rises a further 1.5 °C compared with 1991–2020 (model range 1.0–2.4 °C).
- Days above 35 °C (95 °F) rise from about 3 a year (1991–2020) to about 13 by 2040–2059.
- Frost days fall from about 143 to 126 a year: shorter, milder winters.
Dangerous heat in Denver
Even by 2090 under very high emissions, Denver 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.
Under high emissions
If emissions keep rising (SSP5-8.5), Denver would average 11.4 °C by 2040–2059, with a hottest day around 38 °C and 20 days above 35 °C (95 °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 Denver be in 2050?
Under an intermediate emissions scenario (SSP2-4.5), Denver's average annual temperature in 2040–2059 is projected at about 10.9 °C (range 10.4–11.8 °C across climate models), compared with 9.4 °C in 1991–2020. The hottest day of a typical year reaches about 38 °C (100 °F).
Is Denver getting hotter?
Yes. The last ten years (2016–2025) averaged 1.6 °C warmer than 1951–1980 in Denver, faster than the global average of 1.1 °C over the same period (Copernicus ERA5).
Which city will Denver feel like in 2050?
By 2040–2059, Denver's climate is projected to resemble the climate of Ankara, Turkey today, based on temperature, heat extremes, frost and rainfall.
What would happen under high emissions?
Under a very high emissions scenario (SSP5-8.5), Denver's average temperature in 2040–2059 is projected at 11.4 °C and the hottest day at about 38 °C. The differences between scenarios grow much larger after 2050.
