Overview

• High-pressure system Petralilly brings mostly dry, sunny conditions to northern and eastern Germany today, with more cloud and isolated showers near the southwest and the Alps.
• Sunday is expected to be the mildest day, with many places reaching 14–21°C and around 20°C in parts of the north and west, while southern areas stay cooler.
• A shift to a northeasterly flow around the start of October will deliver a marked cooldown with lower daytime highs and frequent single-digit nights.
• The DWD forecasts light ground frost from Sunday in the east, extending to more regions by midweek, alongside increasing nighttime fog and low stratus.
• In the Alps, light precipitation next week should lower the snowline to below roughly 2,000 meters following the first autumn snow already observed on some peaks, though day-by-day details further out remain uncertain.
