1315. Copernicus: Third-Warmest July, Respite from Record Global Temperatures

In July 2025, Japan's monthly average temperature was the highest of any July since statistics began in 1898. 

In turn, the Copernicus Climate Change Service (C3S) declared July 2025 to be the third-warmest on record, describing it as a break from a continuous streak of record-breaking temperatures.

July 2025 was the third-warmest July on record, with an average surface temperature of 16.68°C, which is 0.45°C higher than the average July temperature from 1991 to 2020. Meanwhile, July 2025 was 0.27°C cooler than July 2023, which was 0.23°C cooler than the second-hottest July, which was in 2024, and 1.25°C warmer than the estimated average temperature for 1850-1900, which was used to define pre-industrial temperatures.

Meanwhile, extreme temperatures were observed around the world. The average temperature over land in Europe in July 2025 was 21.12°C, making it the fourth-hottest July on record. Fennoscandia experienced the most notable above-normal temperatures in Europe, with heatwaves occurring particularly in Sweden and Finland. Heatwaves and wildfires also occurred in Southeast Europe, with Turkey recording a national record high of 50.5°C. Outside of Europe, temperatures were most pronounced in the Himalayas, China, and Japan.

In contrast, Central Europe, western Russia, and parts of Spain experienced below-normal temperatures. Temperatures were well below normal in parts of Antarctica, as well as in North and South America, India, most of Australia, and parts of Africa.
