Overview
- The Deutscher Wetterdienst (DWD) says a heatwave will begin mid‑week with temperatures rising sharply from Thursday and peaking Friday into the weekend.
- The greatest heat is forecast for southwest and western Germany, including the Upper Rhine, Baden‑Württemberg, Rhineland‑Palatinate and Rhine‑Main, where widespread 30s Celsius and localized mid‑to‑high 30s are expected.
- Multiple weather models and forecasters show a non‑negligible chance of isolated readings near 40 °C in southwest hotspots, but the exact peak locations and whether 40 °C will be reached remain uncertain.
- The DWD warns the heat will come with high humidity and tropical nights that increase health risks for older people, children and those with medical conditions, so officials advise drinking more fluids, avoiding midday heat and checking on vulnerable neighbours.
- Meteorologists say a heat‑dome setup driven by an Azores high and Saharan air will also raise the likelihood of severe thunderstorms with heavy rain, hail and damaging gusts from Friday onward, and forecasts should be monitored for changing local warnings.
