Surface air temperatures exceeded 40 ° C in several countries and reached 46 ° C in and in , with zones of the Portuguese territory to reach values close to 48 ° C – which corresponds to a “extreme thermal stress” levelaccording to the criteria of copernicus.
The situation was caused by persistent high pressure systems, known as “”which keeps hot air trapped on the surface, extending heat and dryness. These conditions intensified the and the risk of forest fires.
Hottest June ever in Western Europe
On June 30a average daily temperature in Western Europe reached 24.9 ° Ca new record for the month – value that was repeated in the July 1.
This is one of the highest daily temperatures ever observed in the region during the summer, only outdated at Pico da Estação – between mid -July and mid -August – during the 2003, 2018, 2019, 2022 and 2023 heat waves.

Mediterranean Sea reached record temperature
The waters of the seas also registered extreme values. A between 60 ° s and 60 ° N was 20.72 ° C – O third highest value for Juneonly surpassed by 2024 and 2023.
A wave of marine heat in the western Mediterranean led to highest daily temperature ever for the region in June: 27 ° C, with an anomaly of +3.7 ° C.
As Heat waves in the oceans have devastating effects on marine ecosystems. They can cause migrations and mass deaths of species, compromise the health of underwater habitats and make it difficult to circulate nutrients by reducing the mixture between the superficial and deep water layers.
Droughts and extreme moisture: contrasts in the European climate
In hydrological terms, June was drier than normal in various regions, including West and southern Europe, the United Kingdom, southern Scandinavia and West Russia. A relative humidity in the terrestrial areas of Europe has reached a new minimumwith values 2.7% below average, exceeding the previous record of 2022.
Already the northern Europe (like Iceland, Ireland, Denmark and Baltic) recorded a more humid climate than usual.
Marine ice continues to retreat
No Arcticthe extension of marine ice was 6% below averagethe second lowest ever for a month of June in 47 years of satellite records. Losses were particularly evident in the seas of Barents, Kara and Laptev.
Na Antarcticthe extension of the ice was 9% below averagethe third lower value for the month. As Anomalies were especially notorious in the Bellingshausen Sea and the Eastern South Atlantic.
