Germany's Federal Maritime and Hydrological Service issued a report on the 7th that the average sea surface temperature in the European North Sea reached 11.6 degrees Celsius in 2025, the highest value recorded by the agency since 1969. The report shows that in 2025, the average sea surface temperature in the North Sea will be 0.9 degrees Celsius higher than the long-term average sea surface temperature from 1997 to 2021. The average sea surface temperature in every month of the year was significantly higher than the average for the same period in previous years, with records set in June and December. The German Federal Maritime and Hydrological Service said that it is necessary to further strengthen climate control to buy time to better cope with the effects of climate change and protect coasts and coastal residents.
