Oceans record highest-ever temperature as Super El Nino forms

Copernicus expects the trend to continue, with ocean temperatures now being supercharged by El Niño.

Global ocean temperatures are typically highest in March and April, said Copernicus.

Scientists have recorded the highest temperature ever measured in the world’s oceans, as climate change combines with a powerful El Nino in the tropical Pacific. The global average sea-surface temperature hit a record 21.1 degrees Celsius (70 Fahrenheit) on August 22, according to Europe’s Earth observation agency Cope

The global average sea-surface temperature hit a record 21.1 degrees Celsius on Aug. 22, according to Europe's Earth observation agency Copernicus.

The world’s oceans hit 21.10 degrees Celsius last Saturday, breaking a record set in 2024

The record "is another clear signal of an ocean under growing stress", according to Dr Samantha Burgess from the European Copernicus climate change service.

The average global sea surface temperature outside polar regions reached 21.1°C on Saturday.

Average sea surface temperature outside polar regions was 21.1C on Saturday, latest data finds The world’s oceans were hotter than ever previously recorded on Saturday, according to the latest data. The average surface temperature was 21.1C, with the rising marine heat a stark indicator of the climate crisis. More than
