Scientists say heatwaves and droughts are becoming more frequent and more intense due to climate change.
The Copernicus Climate Change Service (C3S) said temperatures in Europe had been the "highest on record for both the month of August and the summer (June-August) as a whole", AFP reported.
Data showed August was the hottest yet recorded on the continent by a "substantial margin", beating the previous record set in August 2021 by 0.4 degrees Celsius.
"An intense series of heatwaves across Europe, paired with unusually dry conditions, have led to a summer of extremes with records in terms of temperature, drought and fire activity in many parts of Europe, affecting society and nature in various ways," said senior C3S scientist Freja Vamborg.
"Data shows that we've not only had record August temperatures for Europe but also for summer, with the previous summer record only being one year old."
On a global level, August 2022 was the joint warmest August on record.
The average temperature was 0.3 deg C higher than the 1991-2020 average for the month, the monitor said.
