Scientists say average sea surface temperatures outside the polar regions reached the highest ever recorded for July, beating the previous record set in 2023, as devastating heat struck western Europe.
Key facts
- The world's seas were hotter last month than in any July on record, scientists said.
- The average sea surface temperature outside the cold polar regions was the highest on record for July.
- The new July record beats the previous high set in 2023.
- Record July highs were recorded on the Atlantic coast and in the western Mediterranean.
- Severe marine heatwaves affected Europe's seas as devastating heat struck western Europe.
The world’s seas were hotter last month than in any July on record, scientists have said, according to the Guardian. The finding comes as devastating heat struck western Europe during the same period.
Sea surface temperatures hit record highs for July on the Atlantic coast and in the western Mediterranean, the EU’s Copernicus climate change service found. The service also reported that severe marine heatwaves were roiling Europe’s seas.
Globally, the average sea surface temperature outside the cold polar regions was the highest on record for the month, according to Copernicus. The measurement beat the previous July record, which had been set in 2023.
The record reflects sustained warmth across ocean waters that fringe western Europe, where the marine heatwaves coincided with severe heat on land, as reported by the Guardian.
The data was compiled by the EU’s Copernicus climate change service, which monitors sea surface temperatures and other climate indicators across the globe.
Why it matters
Ocean temperatures play a central role in the planet's climate, influencing weather patterns, marine life and coastal communities. Record-breaking sea surface heat, alongside severe marine heatwaves, signals continued warming that can stress ecosystems and intensify extreme weather.
