Overview

• The DWD forecasts a changeable weekend with alternating sun, showers and isolated storms, cautioning that local downpours may reach about 30 liters per square metre in a few hours.
• Thunderstorms may produce gusts around 60–65 km/h and brief heavy rain, with the strongest cells most likely in the south on Saturday and at times in the northwest.
• The west and northwest are expected to turn wetter and cooler, while the east and the Upper Rhine see sunnier spells with highs topping 25–27 °C, especially on Sunday.
• A storm system near the British Isles is expected to push more widespread rain across Germany on Monday, the start of meteorological autumn, with further showers and isolated thunderstorms possible.
• The DWD’s preliminary summer assessment finds a warm, very sunny season—no record—with an average near 18.3 °C, about 227 L/m² of rain, roughly 720 sunshine hours, and two heatwaves punctuated by a wet July that briefly eased drought.
