Record-breaking heat experienced in Saarland, surpassing the annual temperature peak. - Record-breaking heat in the Saarland, making it the warmest day recorded this year.
Saarland, Germany, experienced an unusually early and intense heatwave last week, with temperatures reaching up to 38.3 degrees Celsius on Wednesday afternoon, according to the German Weather Service (DWD) in Offenbach. Although this year's heatwave did not break the all-time record of 40.2 degrees Celsius set in Neunkirchen-Wellesweiler on July 25, 2019, it was still remarkable for its timing and intensity.
The heatwave was part of a broader pattern affecting various parts of Germany and Europe, with the DWD issuing heat advisories for Saarland and several other western and southern German states. In fact, in 2025, Europe witnessed an early, intense heatwave with peak temperatures exceeding 40 degrees Celsius in parts of the continent, including Spain and Portugal.
This early summer heatwave stood out because such high temperatures appeared unusually early in the season, marking a trend of earlier and more intense heatwaves across Europe due to climate change. Meteorologists have noted that heatwaves are becoming both more frequent and arriving earlier than in past decades, with 2025 showing temperatures typical of August arriving already by late May in parts of Europe.
The heatwave in Saarland was historically notable for its timing and intensity, coinciding with climate trends showing more frequent and earlier heat extremes. The location of the highest temperature recorded this year was Saarbrücken-Burbach.
Looking ahead, the DWD forecasts showers and isolated thunderstorms for Rhineland-Palatinate and the Saarland on Thursday, signalling a significant cooling down compared to the previous day's heat. The highs for Thursday are expected to be between 24 and 28 degrees Celsius.
The weather forecast does not mention any new record-breaking temperatures for this year in the Saarland, but the DWD describes this week's heatwave as an "exceptionally intense and unusually early" event. Preliminary data from the heatwave in Saarland is still being verified.
The German Weather Service continues to monitor the situation closely, advising residents to stay hydrated, seek shade when possible, and check for updates on the forecast. As climate change continues to impact weather patterns, it is crucial for everyone to be aware of these trends and take necessary precautions to stay safe during extreme weather events.

- The Commission, in light of the unprecedented heatwaves like the one experienced in Saarland, Germany, could propose a directive on the protection of workers, especially those in environmental-science fields, from the risks related to exposure to extreme weather conditions, such as ionizing radiation emitted during climate-change events.
- As theWhile scientists continue to study the implications of climate change on extreme weather patterns, including heatwaves, it is crucial for the public to understand the role of science in predicting these events and to take necessary precautions, as recommended by the German Weather Service, to mitigate risks and safeguard their health.
