July 2025 in Germany presented a fluctuating pattern of weather extremes, according to the German Weather Service (DWD). The average temperature for the month reached 18.4 degrees Celsius (65.1°F), exceeding the reference period of 1961 to 1990 by 1.5 degrees Celsius (2.7°F). While this surpasses the historical average of 16.9°C, it aligns with the average for the more recent reference period of 1991 to 2020, which stands at 18.3°C.
The monthly average, however, doesn’t fully convey the dynamic nature of the second month of the summer. The month began with a considerable heatwave, culminating in a nationwide high of 39.3°C (102.7°F) recorded on July 2nd in Andernach, Rhineland-Palatinate. This was followed by a sharp temperature decline, leading to a complete absence of summer days across Germany by the end of the first decade. A particularly cold day occurred on July 10th in Meßstetten, Baden-Württemberg, with a recorded temperature of 3.5°C (38.3°F), marking the lowest national temperature for the period.
While the southern half of the country subsequently experienced a greater frequency of summer days, a renewed heatwave failed to develop. Conversely, a northwest airflow towards the month’s end brought unseasonably cool conditions, making lighter jackets preferable to swimsuits.
Precipitation levels were notably above average. Germany received 114 liters of rain per square meter, a 47% increase compared to the 1961 to 1990 reference period. This also surpasses the more recent 1991 to 2020 reference period (87 liters per square meter) by more than 30%.
The northern and northeastern regions, as well as the Alpine foothills, experienced the most significant rainfall, with localized measurements reaching up to 450 liters per square meter. These high precipitation levels were attributed to a trough of low pressure centrally located across Europe, leading to frequent showers and occasionally severe weather events.
Sunshine hours were fewer than in preceding months, totaling 189 hours – approximately 10% below the average for the 1961 to 1990 reference period. The deficit was even more pronounced when compared to the 1991 to 2020 reference period, where nearly a sixth of the expected sunshine hours were absent. While the northwest, northeast and Alpine regions experienced reduced sunshine duration, the southwestern region recorded over 200 hours.
