Baltic Sea under attack: Alarming water levels in MV!

Baltic Sea under attack: Alarming water levels in MV!

On September 18, 2025, the Baltic Sea coast in Mecklenburg-Western Pomerania will once again show its changeable side. The water levels in the region continue to be a central issue as they affect the water levels at important measuring stations such as Wismar, Warnemünde, Althagen and Stralsund. This is particularly relevant as the last severe storm surges in October have already caused damage amounting to 56 million euros. The city of Sassnitz reported a financial need of around 42 million euros for the restoration of necessary infrastructure, while 6 million euros were estimated for sand losses on beaches and dunes caused by artificial nourishment, as the Ostsee-Zeitung reports.

The current water levels as of September 18, 2025 are as follows:

• Zingst: 490 cm (Differenz zum Mittelwasser: -17 cm)
• Bodstedt (Bodstedter Bodden): 489 cm (Differenz zum Mittelwasser: -21 cm)
• Ralswiek (Gr. Jasmunder Bodden): 502 cm (Differenz zum Mittelwasser: -6 cm)
• Bad Sülze (Recknitz): 613 cm (Differenz zum Mittelwasser: -8 cm)
• Stralsund (Knieperteich): 244 cm (Differenz zum Mittelwasser: -3 cm)

Water levels and warning systems

Understanding the different water levels is crucial. The mean low water (MNW) in Warnemünde averages 407 cm, while the mean high water (MHW) reaches 617 cm. The highest flood level ever measured in Warnemünde was 770 cm, recorded on November 13, 1872. The lowest water level was measured at 332 cm on October 18, 1967. The storm surge classes on the German Baltic Sea coast are clearly defined: A storm surge occurs from 1 meter above the mean water level and reaches over 2 meters for very severe storm surges.

Flood warnings are issued by several institutions such as flood control centers, state and district authorities as well as the police and fire brigade. This information is disseminated through various channels including radio, television, sirens and digital warning apps. The population is also regularly informed about current developments on social networks in order to prepare them in good time for possible dangers.

Outlook for the coming days

Things are likely to remain exciting over the next few days as the weather situation changes. Water levels continue to be closely monitored. The communities along the coast are particularly concerned about the forecasts, as the last storm surge caused extensive damage and people are sensitized. Pay attention to the warnings from the responsible authorities and stay informed about the current water levels on the [Level Portal MV] website (https://Levelportal-mv.de/Level_mv.html).

We will continue to keep you updated on developments in the region. As nature plays its own game, residents and authorities must prepare for what might come next to best protect safety and infrastructure.
