Beijing in 2050: climate change in numbers
Beijing 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 Diyarbakır, Turkey today.
2050 = 2040–2059 average, intermediate emissions (SSP2-4.5), median of CMIP6 climate models. “Today” = 1991–2020. Model range for average temperature: 14.5–15.9 °C.

What Beijing's climate will feel like
Matching temperature, heat extremes, frost days and rainfall against the current climate of more than 1,000 large cities, Beijing's 2050 climate is closest to Diyarbakır, Turkey — about 6,400 km away.

| Average daily high | 19.1 °C | 20.9 °C | 22.6 °C |
| Hottest day | 40 °C | 42 °C | 42 °C |
| Frost days | 125 | 110 | 59 |

What changes by 2050
- The average temperature rises a further 1.8 °C compared with 1991–2020 (model range 1.2–2.6 °C).
- Days above 35 °C (95 °F) rise from about 21 a year (1991–2020) to about 43 by 2040–2059.
- Tropical nights — when it never cools below 20 °C — increase from about 77 to 99 a year, making heatwaves harder on health.
- Frost days fall from about 125 to 110 a year: shorter, milder winters.
- Annual rainfall is projected to increase by about 17%, though precipitation projections are less certain than temperature.
Dangerous heat in Beijing
Days a year when the heat index — temperature and humidity combined — reaches 39 °C, the level the US National Weather Service calls Danger: 0 in 1995–2014, 4 by 2050 and 16 by 2090 under intermediate emissions, or 52 by 2090 if emissions keep rising. See where dangerous heat spreads worldwide.
Under high emissions
If emissions keep rising (SSP5-8.5), Beijing would average 15.6 °C by 2040–2059, with a hottest day around 43 °C and 47 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 Beijing be in 2050?
Under an intermediate emissions scenario (SSP2-4.5), Beijing's average annual temperature in 2040–2059 is projected at about 15.2 °C (range 14.5–15.9 °C across climate models), compared with 13.3 °C in 1991–2020. The hottest day of a typical year reaches about 42 °C (107 °F).
Is Beijing getting hotter?
Yes. The last ten years (2016–2025) averaged 2.0 °C warmer than 1951–1980 in Beijing, faster than the global average of 1.1 °C over the same period (Copernicus ERA5).
Which city will Beijing feel like in 2050?
By 2040–2059, Beijing's climate is projected to resemble the climate of Diyarbakır, 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), Beijing's average temperature in 2040–2059 is projected at 15.6 °C and the hottest day at about 43 °C. The differences between scenarios grow much larger after 2050.
