Bengaluru in 2050: climate change in numbers
Bengaluru 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, its climate is projected to feel like Santa Cruz de la Sierra, Bolivia today.
2050 = 2040–2059 average, intermediate emissions (SSP2-4.5), median of CMIP6 climate models. “Today” = 1991–2020. Model range for average temperature: 24.3–25.4 °C.

What Bengaluru's climate will feel like
Matching temperature, heat extremes, frost days and rainfall against the current climate of more than 1,000 large cities, Bengaluru's 2050 climate is closest to Santa Cruz de la Sierra, Bolivia — about 15,800 km away.

Tropical nights in Bengaluru (never cooler than 20 °C)
What changes by 2050
- The average temperature rises a further 0.9 °C compared with 1991–2020 (model range 0.5–1.6 °C).
- Days above 35 °C (95 °F) rise from about 5 a year (1991–2020) to about 24 by 2040–2059.
- Tropical nights — when it never cools below 20 °C — increase from about 183 to 259 a year, making heatwaves harder on health.
- Annual rainfall is projected to increase by about 6%, though precipitation projections are less certain than temperature.
Dangerous heat in Bengaluru
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, 0 by 2050 and 0 by 2090 under intermediate emissions, or 7 by 2090 if emissions keep rising. See where dangerous heat spreads worldwide.
Under high emissions
If emissions keep rising (SSP5-8.5), Bengaluru would average 25.0 °C by 2040–2059, with a hottest day around 38 °C and 31 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 Bengaluru be in 2050?
Under an intermediate emissions scenario (SSP2-4.5), Bengaluru's average annual temperature in 2040–2059 is projected at about 24.7 °C (range 24.3–25.4 °C across climate models), compared with 23.8 °C in 1991–2020. The hottest day of a typical year reaches about 37 °C (99 °F).
Is Bengaluru getting hotter?
Yes. The last ten years (2016–2025) averaged 1.0 °C warmer than 1951–1980 in Bengaluru, about as fast as the global average of 1.1 °C over the same period (Copernicus ERA5).
Which city will Bengaluru feel like in 2050?
By 2040–2059, Bengaluru's climate is projected to resemble the climate of Santa Cruz de la Sierra, Bolivia today, based on temperature, heat extremes, frost and rainfall.
What would happen under high emissions?
Under a very high emissions scenario (SSP5-8.5), Bengaluru's average temperature in 2040–2059 is projected at 25.0 °C and the hottest day at about 38 °C. The differences between scenarios grow much larger after 2050.
