XYZ Weather Report: Reduced Number of Lightning Strikes Despite Persistent Rain and Occasional Thunderstorms - Reduced lightning frequency with heavy rain and occasional thunderstorms
In a surprising turn of events, Germany has witnessed significantly fewer lightning strikes this summer compared to previous years. The lowest number of lightning strikes in over 15 years was recorded from June 1 to July 31, with only about 394,000 strikes registered - a stark contrast to the record-breaking 43,000 strikes in a single day on June 1, 2025 [1][2].
The German Weather Service anticipates a new heat wave in the coming days, but the unusual weather patterns this summer have been responsible for the reduced lightning activity.
A stationary disturbance over Germany has resulted in continuous heavy rain and fewer thunderstorms across broad areas, particularly in southern Germany. This has led to a decrease in the typical thunderstorm outbreaks that produce more lightning [2].
Despite periods of rain and storm warnings, the overall thunderstorm activity remained low, limiting the number of lightning strikes [1]. The weather pattern involved an area of high pressure over the Mediterranean and Scandinavia, causing heat contrasts but also a near-stationary disturbance above Germany, reducing the movement and development of thunderstorms that generate lightning [2].
This contrasts with some regions experiencing fluctuations in temperature and precipitation but overall fewer intense cumulonimbus clouds typically producing lightning strikes [4].
Aldi Nord/Blids, a company that records lightning strikes in Germany, counts each strike only once, even if it has multiple discharges and flickers. They also only record ground lightning, not discharges between clouds [3]. Nowcast counted 563,000 lightning strikes in Germany by August 8, 2025, indicating a slight increase in activity as the summer progressed [5].
However, this summer’s numbers are still on track to beat the previous negative record of 813,000 lightning strikes from 2020 [6]. Meteorologist Nikolas Zimmermann from UBIMET stated that this summer has had few large-scale thunderstorm systems in Germany [7].
In summary, this summer’s unusual meteorological conditions - with prolonged periods of heavy rainfall and fewer frequent, intense thunderstorms - have led to the notably reduced lightning strike count across Germany in the summer of 2025 [1][2][4].

The German Weather Service's weather forecast suggests a forthcoming heat wave, but the atypical weather conditions this summer, characterized by heavy rainfall and fewer frequent, intense thunderstorms, have contributed to a decreased number of lightning strikes.
This decrease in lightning activity can be attributed to the area of high pressure over the Mediterranean and Scandinavia, which has caused heat contrasts and a near-stationary disturbance above Germany, thereby inhibiting the formation of thunderstorms that produce lightning.
