Riding on the back of an intensifying super El Ni\u00f1o, global ocean temperatures have just reached reached a temperature that, until the last few years, would have been difficult to imagine.<\/strong><\/p>\n

On August 22, 2026, the daily global average sea surface temperature (SST) reached 21.1\u00b0C (69.98\u2109) across the non-polar oceans, according to ECMWF\u2019s Copernicus Climate Change Service (C3S)<\/a><\/strong>.<\/strong> The astonishing figure, which is about 0.6\u00b0C (1.08\u2109) above average, surpasses the previous daily record of 21.09\u00b0C (69.96\u2109), set in March 2024. It also eclipsed the previous August record from 2023 (20.98\u00b0C, or 69.76\u2109).<\/span><\/p>\n

What\u2019s even more concerning is the timing of the record.<\/strong> Global sea surface temperatures normally reach their annual maximum in March and April, following the austral summer. That\u2019s because the Southern Hemisphere is home to vastly more ocean area than the Northern Hemisphere. Yet this year\u2019s record arrived in late August, at the peak of Northern summer, bucking a well-established trendline that is clearly visible on Copernicus\u2019s chart.\u00a0<\/span><\/p>\n
