Autumn weather in Germany brings frost and fog

Autumn weather patterns in Germany are characterized by significant temperature fluctuations and frequent fog. Fog occurs when moist air cools to its dew point, causing water vapor to condense into tiny droplets around particles like dust or salt. Meteorologically, fog is defined by horizontal visibility of less than one kilometer.

Recent weather reports indicate extreme shifts, with light frost recorded in southern regions such as Allgäu and parts of Bavaria during clear nights. While morning temperatures dropped near freezing, daytime conditions saw significant warming, reaching up to 24 degrees Celsius along the Rhine. These shifts are driven by high-pressure systems directing polar air into central Europe, followed by rapid clearing and sunshine.
