Rome, 1 July (LaPresse) – The Copernicus Climate Change Service (C3S) and the Copernicus Marine Service (CMEMS) have confirmed that global sea surface temperatures have exceeded the record levels for this time of year, previously recorded in 2023 and 2024. The C3S’s daily sea surface temperature (SST) data exceeded the 2024 levels on 21 June, reaching 20.86 degrees Celsius, slightly above the 20.83 observed in 2023 and 2024. Daily SST data from the Copernicus Marine Service also indicate record temperatures on 21 June, at 21.0 degrees, exceeding the previous records from 2023 and 2024 by 0.1. This new global record for sea surface temperature at this time of year – as explained in a statement – was anticipated following the onset of El Niño conditions in the equatorial Pacific, announced by the World Meteorological Organisation (WMO) on 2 June 2026, in addition to the unusually high sea surface temperatures observed in various oceanic regions in recent months. Copernicus predicts that this temperature record will have consequences for weather patterns, the global climate and marine ecosystems.
