Global ocean temperatures have hit their highest daily average ever recorded, in a worrying sign that Super El Niño is ramping up. The Copernicus Climate Change Service (C3S) confirmed that sea surface temperatures (SSTs) outside of the polar regions reached a sweltering 21.1°C (69.98°F) on August 22.That surpassed the previous record set in March 2024, when daily average temperatures reached their peak at 21.09°C (69.96°F).It also makes August 22 the hottest August day for the world's oceans since records began, beating the previous record set in 2023.This comes as a growing Super El Niño develops in the tropical Pacific, driving a huge buildup of hot water stretching out towards Oceania.Experts say that El Niño is adding further heat to an ocean that has already been warming over many decades due to human–caused climate change.Temperatures in this key area are already around 2.6°C (4.7°F) above the long–term seasonal average, and experts say that the worst is yet to come.According to the Met Office's latest predictions, warming in the Pacific could reach 3°C (5.4°F), while some reports project an increase as high as 4°C (7.2°F). Global ocean temperatures have hit their highest daily average ever recorded, reaching 21.1°C (69.98°F) on August 22
