Overview
- Meteorologists and the DWD report a brief mid‑week rise in temperatures with the peak expected on Friday, locally reaching about 22°C in parts of southern Germany and the Upper Rhine.
- Clear nights during the mild phase will allow strong radiative cooling that can produce ground frost and widespread morning fog in valleys and lowlands, creating slippery roads and low visibility.
- The ADAC urges drivers to switch on dipped headlights in fog and to be cautious where frost and leaf cover can make surfaces slippery.
- Northern and coastal areas should prepare for a wind increase and possible strong gusts at the North Sea from Friday into the early weekend, with showers possible in some northwestern zones.
- A sharp change is forecast for the weekend as polar air from Scandinavia moves in, bringing more clouds, wetter weather and a drop to roughly 11–14°C across much of Germany, shortening the window for outdoor mild conditions.
