Average sea-surface temperatures outside the cold polar regions reached a July record, surpassing the previous high set in 2023. The EU’s Copernicus climate service found record July temperatures along the Atlantic coast and in the western Mediterranean. Severe marine heatwaves are affecting European waters as western Europe endures damaging heat.
