Overview
- Germany is still in a late‑September warm spell with many places seeing daytime highs around 25–30°C and isolated readings above 31°C, a pattern set to persist through Wednesday according to DWD forecasts.
- A west-to-east cold front is expected to arrive on Thursday, 1 October and forecasters warn it will bring thicker cloud, widespread rain in the west, and a risk of isolated thunderstorms with locally heavy downpours especially in NRW and parts of the southwest.
- Temperatures are forecast to fall after the front, with daytime highs generally dropping to roughly 18–24°C in affected regions while eastern and southeastern areas may stay milder for longer.
- The Deutscher Wetterdienst reported that September 2026 was about 2.6°C warmer than the 1961–1990 baseline and ranks among the ten warmest Septembers since 1881, with the south especially sunny and parts of the southwest unusually dry.
- Meteorologists attribute the anomaly to a high over Eastern Europe combined with an Atlantic low channeling warm southern air, but models still differ on how strong and how long the post‑front cooling and rain will be, which matters for farmers, outdoor events and travel plans.
