Bangkok in 2050: climate change in numbers
Bangkok has warmed 1.2 °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 Maracaibo, Venezuela today.
2050 = 2040–2059 average, intermediate emissions (SSP2-4.5), median of CMIP6 climate models. “Today” = 1991–2020. Model range for average temperature: 29.4–30.6 °C.

What Bangkok's climate will feel like
Matching temperature, heat extremes, frost days and rainfall against the current climate of more than 1,000 large cities, Bangkok's 2050 climate is closest to Maracaibo, Venezuela — about 17,200 km away.

What changes by 2050
- The average temperature rises a further 1.2 °C compared with 1991–2020 (model range 0.6–1.8 °C).
- Days above 35 °C (95 °F) rise from about 62 a year (1991–2020) to about 119 by 2040–2059.
Dangerous heat in Bangkok
Days a year when the heat index — temperature and humidity combined — reaches 39 °C, the level the US National Weather Service calls Danger: 11 in 1995–2014, 97 by 2050 and 187 by 2090 under intermediate emissions, or 273 by 2090 if emissions keep rising. See where dangerous heat spreads worldwide.
Sea level at Bangkok
The sea at Bangkok is projected to rise about 73 cm by 2050 and 168 cm by 2100 (IPCC AR6, intermediate emissions). See the full sea level projection for Bangkok.
Under high emissions
If emissions keep rising (SSP5-8.5), Bangkok would average 30.4 °C by 2040–2059, with a hottest day around 41 °C and 152 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 Bangkok be in 2050?
Under an intermediate emissions scenario (SSP2-4.5), Bangkok's average annual temperature in 2040–2059 is projected at about 30.0 °C (range 29.4–30.6 °C across climate models), compared with 28.8 °C in 1991–2020. The hottest day of a typical year reaches about 40 °C (104 °F).
Is Bangkok getting hotter?
Yes. The last ten years (2016–2025) averaged 1.2 °C warmer than 1951–1980 in Bangkok, about as fast as the global average of 1.1 °C over the same period (Copernicus ERA5).
Which city will Bangkok feel like in 2050?
By 2040–2059, Bangkok's climate is projected to resemble the climate of Maracaibo, Venezuela today, based on temperature, heat extremes, frost and rainfall.
What would happen under high emissions?
Under a very high emissions scenario (SSP5-8.5), Bangkok's average temperature in 2040–2059 is projected at 30.4 °C and the hottest day at about 41 °C. The differences between scenarios grow much larger after 2050.
