Danger of flooding on the Baltic Sea: Current water levels alert citizens!
Current water levels in Rostock on June 26th, 2025: An overview of flood warnings, historical data and storm surge classes.
Danger of flooding on the Baltic Sea: Current water levels alert citizens!
Today, June 26, 2025, the current water levels of the Baltic Sea in Mecklenburg-Western Pomerania raise numerous questions. The region, which is particularly often affected by floods, is once again confronted with sometimes critical water levels. The measuring stations in Wismar, Warnemünde, Althagen, Barth, Stralsund, Sassnitz and Greifswald show how dynamic the situation is. The Ostsee-Zeitung reports on the highest and lowest water levels recorded over the years.
A look at the average values shows that the mean low water (MNW) for Warnemünde is 407 cm and the mean high water (MHW) is 617 cm. The highest flood level of 770 cm, which was measured on November 13, 1872, remains worrying. The storm surge classes on the German Baltic Sea coast range from a water level of 1.00 to over 2.00 m, which usually leads to extensive warnings from the responsible authorities.
Water levels in detail
The current water levels illustrate the situation in the region. The water level in Zingst is currently 505 cm, which is a difference of -1 cm from the mean water level. In Bodstedt and Ralswiek the values of 500 cm and 534 cm are also not insignificant. The water levels in the following locations are as follows:
| Location | Water level (cm) | Diff. to mean water (cm) |
|---|---|---|
| Zingst | 505 | -1 |
| Bodstedt | 500 | -9 |
| Ralswiek | 534 | 26 |
| Börzow | 127 | 12 |
| Questin | 89 | -24 |
| Diedrichshagen | 42 | -8 |
The measurements indicate some worrying tendencies. The storm surges represent a permanent natural hazard, especially with strong winds coming onshore. As the Federal Environment Agency emphasizes, we recognize a cyclical course of flood levels, which is exacerbated by severe storms. These events can occur every year, particularly in the winter months, with climate changes further increasing the risk of flooding.
The last severe storm surge in the fall of last year not only caused a major economic burden, but also resulted in damage amounting to around 56 million euros. The city of Sassnitz has already announced a financial need of around 42 million euros to restore the infrastructure after the damage, while an additional six million euros are needed to compensate for the flood-related sand losses on beaches and dunes.
Warning system in focus
In order to better manage such situations in the future, the focus is always on warning systems in the region. Flood control centers, federal, state and local authorities such as the police and fire brigade are responsible for giving timely advance warnings. This information spreads through various channels, from radio and television to digital platforms and social media.
The matter therefore remains exciting, and it is to be hoped that such warnings will continue to be issued in a timely manner in the future. Because, as is so often the case in life, the same applies here: if you act in good time, you can avoid greater damage. Those interested can find the current water level and all other information on the pages of Ostsee-Zeitung, water level portal MV and Umweltbundesamt.
