EU Climate Monitoring Agency: June marks the third hottest month on record globally.

The European Union’s Climate Change Service Bureau, known as the Kepler Climate Change Service, released a report on the 9th stating that the world has just experienced its third hottest June since records began in 1940. The Western European region has also experienced its hottest June on record.
The report indicates that the global average surface temperature for June was 16.46 degrees Celsius, which is only 0.2 degrees Celsius lower than June 2024 and 0.06 degrees Celsius lower than June 2023. However, it is still 1.3 degrees Celsius higher than pre-industrial levels (1850 to 1900).
Furthermore, the Western European region experienced its hottest June on record, with an average temperature of 20.49 degrees Celsius, setting a new record set in 2003.
“In June 2025, an unusually intense heatwave struck most parts of Western Europe… The record-breaking sea surface temperatures in the Western Mediterranean made this heatwave even more intense,” said Samantha Burgess, head of climate strategy at the European Centre for Medium-Range Weather Forecasts. “In a warming world, heatwaves may become more frequent, more intense, and affect more people in Europe.”
The European Union’s Kepler Climate Change Service Bureau regularly releases climate reports, including data on global surface temperatures. The European Centre for Medium-Range Weather Forecasts is an important implementing agency of the Kepler Climate Change Service Bureau.
