Unseasonably Warm Temperatures Forecast Across Germany in December

Sun 7th Dec, 2025

Germany is set to experience a period of uncharacteristically mild weather for early December, with meteorological forecasts predicting temperatures that are more reminiscent of spring than winter. According to the German Weather Service, residents across the country can expect significantly warmer conditions at the start of the week following the second Advent, with double-digit temperatures anticipated even in regions typically known for colder weather during this time of year.

The approaching weather pattern is being influenced by low-pressure systems originating from the Atlantic, which are expected to usher in mild, variable conditions and displace traditional winter weather. Snowfall, which is usually prevalent in higher altitudes during December, is likely to diminish as a result of the sustained warmth. Forecasts indicate that the beginning of the week will be largely dry for most areas after overnight rain shifts east, although new rainfall is predicted to move into western and northwestern parts of Germany as the day progresses.

Daytime temperatures are projected to rise between 10°C and 16°C, with some areas along the Upper Rhine potentially seeing highs of up to 17°C. These temperatures are notably above seasonal averages and are expected to persist in the days that follow. Meteorologists caution that these mild conditions will be accompanied by unsettled weather, with dense cloud cover and intermittent rain likely, particularly on Tuesday. While southern regions of the country may experience clearer spells, the predominant forecast points to overcast skies and sustained warmth.

By Wednesday, most regions will continue to see limited sunshine, as cloud cover remains widespread. However, southern Germany and areas near the Alps may witness occasional breaks in the clouds, allowing for brief sunny periods. The German Weather Service predicts that rain will be most prevalent from the western parts of the country stretching toward the northeast, while other regions will see mainly dry, albeit cloudy, weather.

The anticipated temperature range for midweek remains well above average for December, with highs expected to stay between 8°C and 15°C. Even in elevated areas, where snow accumulation is common during winter months, the current weather pattern suggests that snowfall will be minimal or absent altogether. This trend signals a departure from the cold, wintry conditions typically associated with the Advent season in Germany.

These milder temperatures and persistent cloudiness are being attributed to ongoing atmospheric disturbances over the Atlantic, which are driving moist, warm air masses toward Central Europe. The result is a sustained period of weather that is not conducive to traditional winter activities and celebrations, such as outdoor Christmas markets, which often rely on colder conditions to create a festive atmosphere.

As the week progresses, residents and businesses should remain informed of changing weather conditions, particularly in regions prone to heavy rainfall or where sudden temperature shifts may impact daily routines. The German Weather Service continues to monitor the evolving situation and will provide updates should conditions change or if more severe weather is expected.

Overall, the current outlook suggests that much of Germany will experience a stretch of unusually warm and variable weather through the first half of December, marking a significant deviation from the country's typical winter climate during this period.
