Europe rivers hit lowest water levels in 30 years

river water levels heatwaves Copernicus Climate Change Service climate change European drought

The Copernicus Climate Change Service reports that European rivers reached their lowest average water levels in the summer since monitoring began in 1992. During July and August, major waterways including the Rhine, Danube, Loire, and Seine experienced record or near-record low flows.

This hydrological decline has placed significant pressure on nuclear reactor cooling, hydropower generation, agriculture, and the supply of drinking water across the continent. The report also noted record-high sea surface temperatures along the Atlantic coast and in the western and central Mediterranean, driven by intense marine heatwaves.

The summer of 2026 is ranked as the third hottest on record for Europe overall, while Western Europe experienced its hottest summer ever, with an average temperature of 21.7 degrees Celsius. By the end of the season, 52 percent of the European landmass was subjected to very strong heat stress, with perceived temperatures exceeding 38 degrees Celsius.
