August Weather in Germany 2025: Characterized by warmth, abundant sunshine, and intermittent dryness
August 2025 saw a series of unusual weather patterns across Germany, with some regions experiencing extended periods of heatwaves, while others endured cooler nights and higher-than-average rainfall.
In Saxony-Anhalt, the monthly rainfall remained at around 40 litres per square metre (l/m2), significantly below the target of 59 l/m2, resulting in a deficit of approximately 32%. The northern part of the region was particularly dry, with some areas recording less than 20 l/m2. In contrast, the Alpine region and the Black Forest were significantly wetter, with local amounts of over 200 l/m2 registered.
The average temperature in August 2025 was 18.1°C, 1.6 degrees above the reference period 1961-1990 (16.5°C) and 0.1 degrees above the current comparison period 1991-2020 (18.0°C). Saxony-Anhalt experienced temperatures widely above 30°C, reaching 37°C in Pabstorf in the Harz foreland on the 14th.
The sunshine duration in Saxony-Anhalt amounted to 265 hours, around 34% above the climate value of 198 hours. Compared to the comparison period 1991-2020 (78 l/m2), there was a deficit of around 31 percent in August 2025. Since the start of area-wide sunshine duration measurements in 1951, August 2025 ranks among the ten sunniest.
Elsewhere in the country, the western center, from Saarland to Lower Franconia, had exceptionally high sunshine hours, with values between 275 and almost 300 hours. This contrasted with the exceptionally dry conditions in the broad center of the country, where regions were among the driest with local amounts of less than 20 l/m2 in August 2025.
The heatwave in August 2025 brought widespread temperatures of 32 to 35°C, except for the coastal area, with the highest value nationwide reached in Kitzingen in Lower Franconia on the 15th with 37.1°C. The average temperature in North Rhine-Westphalia was about 18.1 to 18.3 °C, which is approximately 1.6 to 2.0 °C higher than the reference period 1961-1990. Thus, the August 2025 temperature was above the value of the reference period 1961-1990.
Partly very cool nights with single-digit low values and local ground frost occurred in August 2025, with the nationwide minimum air temperature at two meters height being 0.6°C in Deutschneudorf-Brüderwiese in the Erzgebirge.
These weather patterns highlight the ongoing impact of climate change on Germany's weather patterns, with extreme events becoming more frequent and severe. As the country continues to adapt to these changes, it is crucial to monitor and understand these patterns to better prepare for future weather events.
