Germany experienced a notably warmer summer in 2025, exceeding long-term averages and characterized by two distinct heatwaves punctuated by a cooler, wetter period in July, according to initial assessments released Friday by the German Meteorological Service (DWD).
Analysis of data collected from approximately 2,000 monitoring stations nationwide reveals a national average temperature of 18.3 degrees Celsius – 2.0 degrees above the reference period of 1961-1990.
Peak temperatures occurred in early July and mid-August, with Andernach in Rhineland-Palatinate recording the highest nationwide reading of 39.3 degrees Celsius. In contrast, July presented comparatively cooler conditions and increased rainfall, offering some relief to previously experienced dryness. Total precipitation averaged around 227 liters per square meter, approximately five percent lower than the average between 1961 and 1990.
The country enjoyed a significantly higher than average duration of sunshine, reaching approximately 720 hours compared to the usual 614. The southwest region recorded the highest levels of sunshine, peaking at nearly 800 hours in some areas. Regional variations were pronounced; while central Germany often experienced dry conditions, the Alpine regions received the highest rainfall, ranging from 500 to over 700 liters per square meter in localized areas.
