Storm Joshua hits Schleswig-Holstein: hurricane gusts and storm surges are threatening!

Storm “Joshua” reached the North Sea coast on October 24, 2025 and is causing uncomfortable weather conditions in Schleswig-Holstein. The region is currently being hit by stormy weather as the depression slowly moves towards Denmark. The German Weather Service (DWD) has sounded the alarm for the North Sea coast and is warning of hurricane-like gusts that can reach speeds of up to 110 km/h. Gusts of up to 120 km/h can even be in the air in the immediate vicinity of showers.

The effects of “Joshua” are particularly noticeable on the North Sea coast. Weather experts are reporting possible storm surges that could bring high water levels during the day. In Hamburg they predict flood peaks between 1.75 m and 2.25 m above the mean flood. NDR also reports flooded beaches and parts of waterfront promenades, especially in Wilhelmshaven.

The preparations and reactions of the cities

The mayors along the coast, including Hallig Hooge, are approaching the situation calmly. “This is routine for us,” he says, as cattle are herded onto terps. Overall, the DWD urges caution and recommends citizens not to stay outdoors during the storm warning. The ADAC also advises avoiding forest areas, as the risk of trees falling due to gusts of wind is high.

The police initially reported a quiet night with no major weather-related operations. But more alerts are expected as the morning progresses, with the strongest gusts expected between midday and early afternoon. The winds can also increase strongly inland, with gusts of up to 80 km/h possible. SHZ reports that long-distance rail lines are also affected, especially the routes between Hanover and Frankfurt.

Extreme climatic events and their risks

Behind this stormy weather is not only the current low, but also the long-term effects of climate change. The time highlights that rising sea levels and more frequent storm surges significantly increase the risk of water damage to coasts. Last year, a storm surge of 2.27 meters above the mean water level was recorded in Flensburg - the highest value since 1872.

The warmer water temperatures in the North Sea, which reached their highest level since measurements began in summer 2023, could intensify such extreme weather events in the future. The Federal Maritime and Hydrographic Agency also warns that more frequent maritime heat waves are to be expected, which will put further pressure on coastal protection measures.

Given the worsening situation, it remains to be seen to what extent the upcoming storms will continue to affect the region. The experts' warnings and advice are clear: caution is advised - both acutely with the storms and in the long term with regard to the climate consequences.
