Overview

• The Deutscher Wetterdienst reports widespread sunshine with highs around 25–31 °C, locally near 32 °C, peaking Friday and Saturday across much of the country.
• Subtropical air linked to a high over southern Europe, referred to as Oldenburgia, is driving the brief warm surge with origins traced to North Africa.
• From Sunday, a front advancing from the northwest is expected to trigger showers and thunderstorms, with forecasters warning of locally heavy rain and a flood risk in parts of the west and south.
• Some meteorologists cite modelled rainfall peaks of roughly 30–80 l/m² in sections of North Rhine‑Westphalia, though the exact placement of the heaviest bands remains uncertain.
• Outdoor pools in cities such as Cologne are reopening for the weekend, hospitality in Baden‑Württemberg readies for strong terrace trade, and Berlin Marathon organizers have issued heat guidance as temperatures drop sharply next week into the mid‑teens.
