Copernicus reports record global ocean surface temperatures for June

Wednesday, July 1, 2026Science & ClimateWell-covered3 frames

Copernicus services reported that global sea surface temperatures reached record levels for this time of year on June 21, exceeding the highs observed on the same date in 2023 and 2024.
For June 21, the Copernicus Climate Change Service reported a sea surface temperature of 20.86C, while the Copernicus Marine Service reported 21.0C; both were above their previous records for that date.
Copernicus Marine said June 2026 was the hottest June on record for global ocean surface temperatures, with a monthly average of 20.98C, above the previous June record of 20.89C set in 2024.
Reports citing Copernicus said the first half of 2026 was the second-warmest first half-year on record for global ocean surface temperatures, behind the same period in 2024.
Scientists and Copernicus linked the elevated ocean temperatures to the combination of a developing El Niño event and longer-term human-driven climate warming.
Copernicus warned that the new ocean temperature record is expected to have consequences for weather patterns, the global climate and marine ecosystems.
Several reports said scientists expect additional temperature records could be broken in the coming months if current ocean warmth continues and El Niño strengthens.

Both agree: Record ocean warmth reflects both a developing El Niño and longer-term human-driven warming, with expected consequences for weather patterns, the global climate, and marine ecosystems.
They split on: Whether the story is about climate risk already compounding into a public problem, or about institutions managing difficult conditions without treating the record itself as the point.
