Overview
- The German Weather Service has issued heat warnings as temperatures rise from Wednesday and operational forecasts show widespread highs of 30–38°C in the coming days.
- Forecasters and multiple model runs flag a likely peak around June 21–22 with many simulations showing 35–38°C and some private or AI runs indicating local extremes near 40°C, especially in the West and Southwest.
- Heat will concentrate in river basins and urban basins such as the Oberrhein, Rhein‑Main and Breisgau where heat can pool and tropical nights may follow, raising heat stress for residents.
- Meteorologists warn the intense heat and humidity will increase instability and lead to localized severe thunderstorms from Friday with heavy rain, hail and strong gusts possible.
- Models agree on a strong hot episode but diverge on duration so authorities stress preparedness now, especially for older people and those with health conditions, and services should watch for record highs and strain on hospitals and infrastructure.
