On the 9th, the EU climate monitoring agency Copernicus Climate Change Service released the latest data confirming that June 2025 is the third-hottest June in the world. The average surface temperature is 16.46 degrees Celsius, 0.47 degrees Celsius higher than the average for June from 1991 to 2020. Meanwhile, mainland Europe experienced two significant heatwaves in mid-June and late June to early July 2025. The first heatwave peaked from June 17 to 22, affecting much of Western and Southern Europe. The second heatwave occurred between June 30 and July 2, with more extreme temperatures in the same area. Some countries have surface temperatures above 40 degrees Celsius, and Spain and Portugal have temperatures as high as 46 degrees Celsius. Both heatwaves are linked to a continuous high-pressure system called the “heat dome,” which traps warm air in the air, causing long periods of hot, clear, and dry weather.
