Overview

• The German Weather Service expects widespread sunshine with highs of 27–31°C on Friday and Saturday, locally touching about 32°C in the southwest and along Rhine, Neckar and Danube valleys.
• From Sunday, clouds, rain and thunderstorms spread in with a marked temperature drop, bringing many places down to the mid-teens early next week.
• In North Rhine-Westphalia, fresh model runs cited by forecaster Dominik Jung signal 30–80 l/m² in some areas and warn of possible local flooding, which forecasters stress remains dependent on evolving conditions.
• Events and businesses are seizing the warm window, with Munich’s Oktoberfest opening in summer-like conditions near 28–30°C and several cities keeping or reopening outdoor pools and beer gardens.
• The pattern reflects a broader regional shift, with Spain’s Aemet forecasting a 5–10°C weekend cooldown in Andalusia after recent highs near 40°C.
