June 2025: Record heat and sunshine blast all expectations!

Sonneberg, Deutschland - What's going on in June 2025? The past month has raised the heat to a whole new level and was the fifth heatest June since the start of the recordings. According to Insuedthueringen.de 15.8 degrees Celsius, which resulted in a deviation of 4.2 degrees compared to the climatological means. For many, it is hardly surprising that five of the six warmest Junimonates have been taking place in this period since 2019.

At the beginning of the month, however, the weather was still moderate. The temperatures were in the usual area until June 11th. Interestingly, two thirds of the total precipitation quantity of the month fell in the first eight days. A perfect framework for the event of the mountain railway run on June 1st, which was initially shaped by a covered sky and light rain before the sun finally broke through.

the climate trend

The weather situation was not only a local peculiarity, but also reflects a larger climate phenomenon. The Climate report of the UWR shows that June 2025 in Germany was too warm, too dry and sunnier than expected. In the south of the country, temperature deviations of up to 3 degrees occurred, which made this June at the hottest time since the summer of 2003. Munich-Stadt probably recorded eight hot days with maximum values ​​of at least 30 degrees.

But the weather variation also brought confusion. The precipitation had large regional differences, while the month in German space was slightly too dry with -13 %. In contrast, the northwest of Germany experienced a wet June compared to the climate agent. In addition, June 2025 was the least month since 2009, with only about 211,642 flash loads. Bavaria was the center of thunderstorms, with almost 65,000 lightning incidents.

long -term weather changes

The developments that we currently observe fit into the overall picture of climate development in Germany, which is dealt with in detail in the Monitoring report 2023 of the Federal Environment Agency. Accordingly, the temperature in Germany has increased by 1.7 ° C since 1881, and much faster than the global average. Scientists agree that this warming cannot be explained solely by natural causes.

The forecasts for the future are also thoughtful. According to the research, the temperature could rise between 0.8 ° C and 2.3 ° C by 2060, depending on the climate protection scenario. This means that we have to adjust to more hot days and less cold periods. For example, the number of hot days in Germany, which has more than tripled since 1951, could continue to rise.

The weather events of June 2025 are a sign of the times. It remains exciting to observe how our climate develops - for us here in Cologne and all over Germany. In any case, the weather situation gives us everyone an impressive insight into the challenges that could wait.
