Overview
- A brief thunderstorm-led cooldown over the weekend is ending and the Deutscher Wetterdienst and other forecasts say a new heat episode will build from Tuesday.
- DWD projects widespread daytime highs above 30°C midweek with many areas 30–37°C and regional hotspots such as the Upper Rhine and Franconia reaching about 39°C.
- Nighttime cooling will be limited in parts of the country and some places may experience tropical nights with temperatures staying above 20°C.
- Multiple operational model runs show a possible early‑August spike above 40°C, but the DWD stresses those long‑range signals are uncertain and not an authoritative forecast.
- The new heat will add to already dry soils and recent record warmth, raising risks to public health, agriculture and wildfire response and making heavy convective storms with hail and gusts an additional hazard.
