Hot June 2025: record temperatures and alarming drought in the north!
What a start to summer! June 2025 caused temperature records to tumble in northern Germany. With lots of sun, little rain and temperatures above the long-term average, this month will certainly be remembered. The German Weather Service (DWD) concludes: June was too warm and too dry across Germany. In Lower Saxony in particular, the average temperature was 17.5 °C, which is over two degrees above the usual values. Bremen can't complain either: Here the monthly average was 17.3 °C and was therefore also significantly higher than the usual 15.5 °C North24 reported.
The sun shone brightly: Bremen and Bremerhaven recorded 235 hours of sunshine, while Lower Saxony experienced 241 hours of sunshine - almost 20% more than usual. However, the rainfall was anything but satisfactory. Only 63 l/m² of rain fell in Bremen, which is 15% less than usual. The situation was similar in Lower Saxony: 62 l/m² is also below target. In fact, this was the fifth month in a row in which rainfall was significantly too low since February.
The effects of climate change
The climate changes we are currently observing are no coincidence. Climate change is becoming more and more apparent. The soil is drying out, heat waves are becoming more frequent and solar radiation is exceeding normal levels. According to that German Weather Service Human influence on greenhouse gas concentrations has increased significantly since pre-industrial times. Factors such as industry, traffic and agriculture are contributing to temperatures continuing to rise.
The development of extreme values is particularly alarming. Studies show that since the 1950s, the number of hot days has more than tripled from about three to ten per year. On the other side of the coin are ice days, which have decreased from 28 to just 19 days per year. These developments are results that are caused by the increasingly changing climate balance. Overall, the temperature in Germany has risen by 1.7 °C since 1881, with the increase being particularly significant in the last two decades Federal Environment Agency determines.
A look into the future
What awaits us in the coming years is still uncertain. Forecasts show that temperatures in Germany could rise by up to 4.7 °C by 2100 if emissions remain so high. Climate protection is therefore a central issue that will not only affect us, but also future generations. It is crucial to reduce emissions and face the challenges ahead.
In view of all these developments, it is clear: something is happening! Climate change affects us all and it is time to take action. Whether it is individual actions or large-scale political decisions, we must all do our part to protect our environment and leave a world worth living in for future generations.
