Storm surges on the Baltic Sea: Current water levels are alarming the region!
Today, July 2, 2025, the water levels on the Baltic Sea and in the adjacent waters are the focus of attention. Storm surges on the Baltic Sea occur several times a year, putting residents on alert. According to the Federal Maritime and Hydrographic Agency, there were five storm surges from July 2022 to June 2023 and even seven storm surges in the 2021/2022 season [kn-online.de].
In addition, it can be seen that two low water events were recorded in the 2022/2023 season, while there were four low water events in the previous season. The classification of storm surges includes different categories: A storm surge is measured between 1.00 and 1.25 meters above the mean water level, while severe storm surges reach 1.50 to 2.00 meters and very severe storm surges are over 2.00 meters.

Flood warnings in Germany are comprehensively organized. Several authorities are responsible, such as the federal, state, district, police and fire departments. There is an active flood control center in every federal state. The warning channels are diverse: radio and television, loudspeaker trucks, sirens, websites, warning apps, social media, digital billboards and personal warnings ensure that the population is informed in good time.
Rules of conduct during storm surges
Proper preparation for a storm surge is essential. The recommended rules of conduct include, among others:

- Batteriebetriebene Radios und Taschenlampen bereit halten
- Fluchtwege planen und Vorräte anlegen
- Das Ufer meiden

The water levels in the surrounding rivers and canals are already of interest. The website hsi-sh.de confirms that the water level in the North Sea is currently 538 cm, and the Eider is not far off at 536 cm. These values are not insignificant and could change quickly depending on the weather, encouraging residents to be vigilant.
Finally, it should be noted that the frequency of storm surges and the associated level fluctuations continue to pose challenges for our coastal regions. The descriptions of these events not only underline the urgency of taking early action, but also the importance of staying informed about current developments. Residents are well advised to adhere to the rules of conduct and actively monitor the current status of information.
