EU Copernicus reports western Europe hit 2.5 °C above average this summer, making it the continent's third hottest on record and triggering widespread heat stress and health impacts.

Surface air temperatures in western Europe were 2.5 °C above the decadal average from June to August, EU Copernicus climate service reported Friday, making the season the continent’s third‑hottest on record.

Record heat across western Europe

The Copernicus update shows that the June‑August period set a new high for the region, surpassing the previous benchmark by more than two degrees Celsius. The agency classified the heat as "very strong" in more than half of the western European landmass, with measured values feeling hotter than 38 °C.

Heat stress spreads eastward

While western Europe endured the most intense temperatures, the report notes that milder yet still dangerous heat persisted across the rest of the continent. Mortality data compiled by national health ministries indicated an uptick in heat‑related deaths during the same period, underscoring the lethal potential of even less extreme temperatures.

Implications for the season and future outlook

Overall, the summer ranks as Europe’s third hottest on record, trailing only the 2003 and 2019 heatwaves. The agency warns that such anomalies are consistent with long‑term climate trends and may become more frequent if greenhouse‑gas concentrations remain high.

European agricultural ministries reported that prolonged high temperatures stressed crops, reducing yields in several southern regions. The combination of heat stress, health impacts, and agricultural strain paints a stark picture for policymakers as they prepare for the next growing season.

EU climate officials said the Copernicus service will continue to monitor temperature deviations and provide weekly updates to national authorities. They urged governments to activate heat‑health action plans and to support farmers facing crop losses.

Analysts highlighted that the current data reinforce the urgency of emission‑reduction commitments made under the Paris Agreement. As the continent confronts another extreme summer, the need for coordinated climate adaptation measures grows more pressing.
