Overview

• The DWD forecasts widespread sunshine and highs around 27–31°C on Saturday, locally up to 32°C in the south and southwest, driven by high pressure “Oldenburgia” with some outlets citing even higher local peaks.
• A fast-moving front arrives from the northwest on Sunday with increasing cloud, rain and isolated to locally strong thunderstorms, and a risk of heavy precipitation in places.
• Temperatures tumble into early week, with many areas only reaching roughly 13–19°C on Monday and notably cooler nights thereafter.
• Restaurants and beer gardens are reopening or extending outdoor service to capitalize on the brief surge, and several cities are keeping select outdoor pools open for the weekend.
• Berlin Marathon organizers urge runners to hydrate, wear caps and use all aid stations as warm conditions are expected during the race, with showers or storms possible later.
