Red alert: Storm surge on the Baltic Sea brings high water levels!
It will be turbulent in the coastal regions on the Baltic Sea today, June 16, 2025. A storm surge has been announced that will primarily affect the Baltic Sea coast of Mecklenburg-Western Pomerania. The weather forecasts indicate that water levels in Schleswig-Holstein are expected to rise 1.50 meters or more above mean high water. “It could be a very severe storm surge,” warns Environment Minister Tobias Goldschmidt and calls on residents to be careful.
As the Baltic Sea newspaper reports, the peak of the storm surge could be reached on Friday evening, with the trend of the tide near the Bay of Lübeck reaching the level of a severe storm surge. A water level of up to 2.00 meters above mean flood is predicted for the Flensburg Fjord.
Measuring stations and water levels
The current water levels are recorded at various measuring stations, including Wismar, Warnemünde, Althagen, Barth, Stralsund, Sassnitz and Greifswald. According to the data from bsh.de The values are in the usual range, but with potential fluctuations due to the storm surge. Currently, the highest flood level (HHW) in Warnemünde in history is 770 cm, measured on November 13, 1872. The mean high water (MHW) is 617 cm and the mean low water (MNW) is 407 cm.
The now common classification of storm surge classes is particularly important for residents. Values between 1.00 and 1.25 meters above the average water level are considered a storm surge, while a severe storm surge is only classified from 1.50 meters and a very severe storm surge above 2.00 meters. Such warnings are issued by various institutions such as federal, state and local governments and disseminated through different channels, be it radio, television or even social media.
Consequences of the last storm surges
The devastating effects of storm surges are not unknown to local residents. That's what she reported star that the last severe storm surge in October last year caused damage amounting to 56 million euros, with the city of Sassnitz in particular reporting a financial need of around 42 million euros to restore the ailing infrastructure.
After the years 2017 and 2019, which were also affected by storm surges, there was some rethinking in prevention. Experts warn that the current storm surge could last up to 40 hours and that there are fears of subsequent steep bank collapses and flooded beach ridges at the mouth of the mule. Serious damage to beaches and dunes caused by artificial nourishment has already been identified.
With the strong warning given by the Danes, another dimension has been added. Police in Denmark are advising residents and holidaymakers to leave coastal areas by Friday morning to protect themselves from potential flooding in popular summer home areas.
