Flood nightmare on the Baltic Sea: Current water levels and warnings!

The coast of Mecklenburg-Western Pomerania is currently in a worrying state of flooding. On July 2, 2025, the measuring stations in Wismar, Warnemünde, Althagen, Barth, Stralsund, Sassnitz and Greifswald reported worrying water levels. While the average high water (MHW) for Warnemünde is 617 cm, there has been a record high of 770 cm in the past, which was measured on November 13, 1872. In contrast, even the lowest values ​​should not be underestimated; 332 cm was recorded on October 18, 1967, making residents and tourists think about how vulnerable the region is. The Ostsee-Zeitung reports that flood warnings are issued by various bodies such as flood control centers, the police or the fire department to inform the population in a timely manner.

And what remains of the recent storm surges? In October last year, a strong storm surge caused damage amounting to 56 million euros. The city of Sassnitz in particular is struggling with a financial requirement of around 42 million euros to restore the tourist infrastructure and harbor protection systems. The renovation of the beach area, whose sand losses are estimated at around 6 million euros, is also urgently needed. Floods not only have an impact on nature, but also have far-reaching economic consequences for residents and companies.

Flood hazards and risk management

But what about flood risk management? This is where flood hazard maps come into play. These maps show the potential extent of flooding as well as the depth of the water. They also provide information about possible damage and people affected. The LUNG MV emphasizes that the hazard maps provide important information for protected areas, such as drinking water protection areas and UNESCO World Heritage sites. What is new is the representation of areas protected by technical flood protection systems, which play a significant role in flood risk.

These maps are due to be reviewed by December 22, 2025. There are often residential areas that are classified as at risk but are still approved for reconstruction. This shows how urgent the question of a safe construction policy in risky zones is. The Statista highlights that almost 400,000 people in Germany could be at risk of flooding in the coming years, especially along the Rhine and its tributaries. It is also shocking that over 30 percent of German rivers have been significantly changed, which increases the risk of flooding.

A look into the future

What's next? Climate change has a significant influence on the flood situation. A warmer atmosphere can store more water, which means more intense precipitation and more frequent heavy rain events can be expected. In order to minimize future damage, consistent expansion of flood protection is essential. The need for natural retention spaces is becoming increasingly apparent. Nature must be given more space again to buffer excessive amounts of water and protect the infrastructure.

The challenges are great, but it is up to society to actively shape the change. Planning and awareness are required – there is something to be done! In any case: keep your eyes open and stay informed about the dangerous situations occurring along the coastline. Only together can we ensure that our living space remains livable in the future.
