Rosenheim: Germany's lightning capital with records and dangers!

Rosenheim, Deutschland - Rosenheim, a city in Upper Bavaria, crowned Germany in Germany in 2024. With an impressive lightning density of 2.98 flashes per square kilometer, Rosenheim exceeds all other cities. It is particularly striking that the lightning density in Rosenheim rose sharply in comparison to only 0.7 flashing per square kilometer in 2020 and the region is particularly often affected by thunderstorms, which reflects the lightning distribution of the thunderstorming of southern Germany. According to Merkur , this susceptibility to thunderstorms is primarily due to three key factors: moisture, unstable layering in the atmosphere and a stronger Cover drive.

Compared to Rosenheim, other Bavarian cities such as Memmingen and Kempten also reach high lightning densities, while the district of Altötting with 0.64 flashes per square kilometer has the lowest lightning density in the room. The district of Rosenheim itself also has a considerable lightning density of 2.12 flashes per square kilometer, but Rosenheim remains unchallenged with its top position. These developments are clearly shown in the latest flash statistics: In 2023, a total of 209,619 lightning was registered in Germany, which means on average every two and a half minutes, so ZDF .

lightning in German cities

In a German -wide comparison study on lightning frequency, it turns out that Frankfurt am Main as the largest city with 1.32 flashes per square kilometer has the highest lightning density among the big cities. Munich follows at 1.16 flashing per square kilometer, while Hamburg, Cologne and Berlin show significantly lower values: 0.92, 0.54 and 0.43 flashes per square kilometer. Bayreuth applies to a quieter region in Bavaria, which at only 0.11 flashes per square kilometer has the lowest lightning density. Pforzheim and Herne are also on the list with 0.12 and 0.13. According to Spiegel Aldis/Blids.

The frequency of flashing is heavily weather -dependent and increases particularly during summer when heat and moisture prevail. Another aspect is that thunderstorms in southern Germany, near the Alps, occur much more frequently, which influences the lightning density in Rosenheim and other regions of the Alps. Despite the high lightning absorption, it must be emphasized that the risk of direct lightning strike is classified as low for individuals. Nevertheless, overvoltage damage can occur near lightning strikes. For this reason, lightning protection is advisable in the household, especially for high -quality electrical devices.

All of these factors illustrate why Rosenheim is considered Germany's lightning capital according to the current measurements and the trend of past years and at the same time underline the importance of preventive measures against lightning damage.
