Flood warning on the Baltic Sea: Current water levels and risk of storm flood!

This day, June 11, 2025, the residents of the Baltic Sea coast in Mecklenburg-Western Pomerania are facing a serious challenge: a storm surge that is rapidly on the road. Report by Ostsee-Zeitung Runze is to expect significant water levels. Measurements of the water levels already show that the Baltic Sea is currently under the influence of strong east wind that significantly increase the water levels. Those affected are asked to be attentive and take precautionary measures in good time.

The levels at important measuring stations such as Wismar, Warnemünde and Greifswald give rise to concern. Under the current conditions, a heavy storm surge could be imminent in regions such as the Lübeck bay, with values ​​of 1.50 meters to be expected above the middle flood. Environment Minister Tobias Goldschmidt has called on the coastal residents to inform themselves in good time and take appropriate precautions.

What does that mean for the residents?

The phenomenon storm surge should not be underestimated. According to Stern starts a storm surge as soon as the water level is 1 meter above the normal value, whereby heavy storm surges are already counted from 1.5 meters. With the current forecasts, a water level of around 1.40 meters in Greifswald and around 1 meter in Koserow are expected. This extreme location means that here and there with floods, especially in the beach walls, can be expected.

The recommendations to the residents are clear: switch off electricity and gas, secure important objects and create food and drinking water supplies. If necessary, retreats should be searched for in higher areas. It is of great importance to keep hand luggage ready for evacuation requests.

damage and preliminary warnings

It was not until October 2024 that the last severe storm surge left massive damage of around 56 million euros. The tourist infrastructure and port protection systems were particularly affected. The city of Sassnitz reported a high financial requirement of around 42 million euros to restore the infrastructure. This shows how important it is to be prepared for such events and act in good time.

In addition, there are reports from Denmark, where the police asked residents and vacationers in the south and east of the country to leave the coastal regions. The storm surge also has an impact on ferry connections, especially between Rostock and Gedser, which must be canceled due to the current weather conditions.

The hydrological developments on the Baltic Sea are mostly taken from the Bundesamt für Seifenschiffahrt and Hydrography . These reports repeatedly draw attention to the importance of the control of water levels and water temperatures, as they represent an important part of the prediction and danger of hazard.

While the eyes of the coastal dwellers are focused on the weather reports, the hope remains that serious damage can be prevented with adequate measures. It is worth staying attentive and paying attention to the situation.
