Oceans could be on track for the hottest red day and could be checked for new records

  • In the summer of 2026, ocean surface temperatures are expected to exceed the Copernicus threshold by 21.0°C
  • Marine heatwaves could cover nearly 82% of the ocean, and the average region-wide temperature in the so-called “garbage patch” in the North Atlantic could reach record highs
  • Copernicus predicts that the warmest temperatures from El Nio will cause the ocean to remain above 90% of the system’s temperature thresholds in the Earth system

Ocean surface temperatures in the summer months are already breaking records, and the worst may be yet to come. Copernicus Marine Service has released new data showing average sea temperatures.

According to Copernicus, 21 degrees of ocean surface temperature in the summer months is expected to be reached in the regions of the planet with the highest temperatures, which are expected to increase in 2023 and 2024. With this, the ocean’s record-breaking temperature — 21.0°C (69.8°F) — will remain the average record for the month.

Copernicus Marine Service predicts that by 2026, ocean temperatures will increase steadily and remain above the threshold temperatures for months. In addition, with record-breaking temperatures, the ocean will cover almost 82% of the entire ocean, and the average temperatures in the North Atlantic “garbage patch,” named the Sargasso Sea, could be the highest ever.

It is the El Nio phenomenon that is expected to drive this. Copernicus data suggests that the phenomenon will cause global ocean temperatures to rise in 2026. The Copernicus Climate Change Service’s Karl Bounte said that, as a result of the El Nio, ocean temperatures will remain at record levels and could reach new highs.

In public reports, it is also noted that ocean temperatures could exceed 90% of the temperature thresholds in the Earth system, which is associated with the gradual warming of the planet. Warmer ocean temperatures can lead to extreme weather events, stronger hurricanes, and increased rainfall, as well as affect marine life. Wind patterns can also change, which could lead to more extreme storms and droughts.
