The city of Speyer in the state of Rheinland-Palatinate was Germany’s “lightning capital” in 2019. Siemens’ lightning information service BLIDS (which stands for Blitz-Informationsdienst von Siemens) detected just under 3.1 lightning strikes per square kilometer in Speyer in 2019. The cities of Rostock on the Baltic coast and Lübeck in the state of Schleswig-Holstein took second and third places with 2.6 and 2.5 ground flashes per square kilometer, respectively. Germany’s lowest density of lightning strikes was recorded in the Bavarian cities of Hof and Bayreuth, where considerably fewer than 0.1 lightning strikes per square kilometer were recorded. The Bavarian city of Schweinfurt, which was No. 1 in Siemens’ 2018 lightning atlas, was also at the bottom of the list, recording 0.1 lightning strikes per square kilometer in 2019. With lightning striking just under 2.3 times per square kilometer, Potsdam led the country’s list of state capitals in 2019, followed by the neighboring city of Berlin (rounded off: 2.2). Berlin is also the German state registering the highest lightning density, while Bavaria recorded the highest number of measured ground flashes in 2019. Overall, at 329,000, BLIDS recorded its lowest number of lightning strikes, around 26 percent fewer than in 2018.
