Overview
- As of Thursday, June 11, Germany remains in a cool, unsettled Schafskälte with multiple DWD warnings for thunderstorms, heavy rain, hail and localized flooding.
- Operational models from ECMWF, NOAA/GFS and others now show a high‑confidence shift starting the coming weekend that would bring widespread 25–32°C and regional spikes to 30–36°C in mid‑June.
- Several model runs project the first 2026 'Wüstentag' (≥35°C) in parts of southern and western Germany, but forecasters stress exact peak dates and local extremes remain uncertain because convective storms can interrupt warming.
- Long‑range ensembles (ECMWF, CFSv2, Copernicus) increasingly indicate a warmer‑than‑average summer, with a strong signal for an unusually hot July and roughly an 80% chance of above‑normal temperatures.
- Meteorologists link the rapid swings to a weakened, meandering jet stream and unusually warm adjacent seas, and health and policy bodies warn that more frequent intense heat will raise mortality, strain care systems and add economic costs unless binding heat‑protection measures are expanded.
