Overview
- The German Weather Service (DWD) said on Saturday that a large high‑pressure bridge is channeling subtropical air northward, creating the countrywide late‑September warm spell.
- Official forecasts call for widespread daytime highs in the mid‑20s and local peaks of about 30–32 °C along the Oberrhein and in parts of southwest Germany, with some single‑station decade records possible.
- Northern coasts face a very different threat as the same pattern brings stormy, gusty conditions there, with the DWD warning of strong coastal gusts up to storm force.
- Models and national media predict the heat will persist into the start of next week with multiple warm days, but they also show a probable shift to cooler, wetter conditions in the second half of next week with growing uncertainty.
- Climate experts say the episode reinforces an unusually warm 2026, could boost national sunshine and temperature records, and adds to this year's heat‑related health burden noted by public‑health agencies.
