A severe heatwave has reached Northern Germany, with temperatures exceeding 30 degrees Celsius in many regions as of June 24, 2026. The German Weather Service (DWD) has issued heat warnings for Lower Saxony, Hamburg, Bremen, southern Schleswig-Holstein, and southwestern Mecklenburg-Vorpommern. Meteorologists warn that the heat, which is expected to reach up to 38 degrees by Saturday, will persist at least until Sunday.
Where are the highest temperatures expected?
While coastal areas and islands will remain cooler, with temperatures between 24 and 29 degrees, inland regions face extreme heat. According to the DWD, Lower Saxony is set to see highs of 34 degrees today, with some areas potentially reaching 38 degrees by Friday and Saturday. Similar highs of up to 36 degrees are expected in Hamburg, Schleswig-Holstein, and Mecklenburg-Vorpommern. Weather expert Frank Böttcher described the situation as the “strongest heatwave we have ever had in June,” noting that such early and prolonged extreme heat is unusual for the region.
How are schools and events responding?
School policies remain decentralized, with many institutions leaving the decision to hold classes or grant “hitzefrei” (heat leave) to parents and local administrations. In Hamburg, several primary schools have cancelled sports festivals, while in Lower Saxony, some secondary schools have restricted instruction. Major public events, including the Harley Days and the Hamburg half-marathon, are currently scheduled to proceed with safety measures like free drinking water and cooling stations. Conversely, other events, such as the Schorsenbummel in Hannover and the summer festival of the Volkssolidarität in Rostock, have been cancelled or postponed due to safety concerns.
What are the health risks and safety measures?
Health officials and meteorologists warn of significant risks, including heat-related circulatory collapse and heart rhythm disorders. Tim Staeger of the ARD Weather Competence Center explains that high humidity can exacerbate the danger by preventing the body from cooling itself through sweating, creating a “sauna-like” effect. Mecklenburg-Vorpommern’s Social Minister, Stefanie Drese (SPD), has urged citizens to check on elderly and vulnerable neighbors, specifically advising against alcohol consumption during the peak heat hours between 16:00 and 18:00.

No, there is no standardized temperature trigger for “hitzefrei” in Lower Saxony; each school makes its own determination based on local conditions.
What is being done to protect infrastructure?

Is the current water temperature unusual?
Yes, according to weather expert Frank Böttcher, current water temperatures of 17 to 20 degrees in the Baltic and 18 to 19 degrees in the North Sea are approximately 2 to 3 degrees above the seasonal average.
