Baltic Sea under water: Current water levels and storm surge warnings!
October 27, 2025 will once again bring us exciting water levels in the Baltic Sea in Mecklenburg-Western Pomerania. Current values from various measuring stations show that the amounts of water vary greatly and it is important to keep an eye on developments. The measuring stations in Wismar, Warnemünde, Althagen, Barth, Stralsund, Sassnitz and Greifswald share precise data to give citizens a better feel for the situation on the water. According to the Ostsee-Zeitung, water levels in Warnemünde report that the average low over a ten-year period is 407 cm, while the average high water level is 617 cm. The highest flood level ever measured in Warnemünde was an impressive 770 cm, while the lowest value was 332 cm, recorded back in 1967.
But what does it look like today? A look at the current water levels provides a deeper insight into the situation:
- Zingst: 498 cm (Diff. zum Mittelwasser: -9 cm)
- Bodstedt: 496 cm (Diff. zum Mittelwasser: -14 cm)
- Ralswiek: 514 cm (Diff. zum Mittelwasser: 6 cm)
- Schwerin (Neumühle, Neumühler See): 416 cm (Diff. zum Mittelwasser: 42 cm)
Storm surges and warning systems
It is also important to note the storm surge system on the German Baltic Sea coast. Storm surges are divided into different classes:
- Sturmflut: 1,00 – 1,25 m über mittlerem Wasserstand
- Mittlere Sturmflut: 1,25 – 1,50 m
- Schwere Sturmflut: 1,50 – 2,00 m
- Sehr schwere Sturmflut: über 2,00 m
When high water levels are reached, flood control centers, federal, state, district, police or fire departments are usually deployed to inform the population about the danger. These warnings come into citizens' living rooms via various channels, such as radio, television, loudspeaker trucks or even modern warning apps.
Financial consequences and climate change
The last severe storm surge was devastating: the damage amounted to around 56 million euros. The city of Sassnitz is particularly affected, as it has currently reported a financial need of around 42 million euros to restore its infrastructure. The beach, which suffered greatly from the flood events, also needs artificial nourishment, for which around six million euros are planned.
In a larger context, it is important to understand the underlying factors of flood risk. Floods are the most common natural disaster, causing nearly 37 percent of all such emergencies globally since 2000. We should prepare for more frequent flood events, especially in light of climate change, which is increasing precipitation levels and storing more water in the atmosphere. In Germany, 7.6 percent of all addresses are exposed to such risks, threatening around 400,000 residents, especially along the Rhine and its tributaries.
If you look at the future, it becomes clear: In order to avoid serious damage, a more intensive expansion of flood protection will be essential. It is important to include natural retention areas more in the planning and to stop the destruction of flood areas. The road to improvement is long, and the questions of security and climate adaptation must be continually reassessed.
The situation requires a joint solidarity in order to respond adequately to the challenges. So it's not just a matter of waiting and drinking tea, but of taking action!
