Germany has recorded its hottest night since measurements began, with the thermometer failing to drop below 29.4°C in the eastern town of Kubschütz, the national weather service DWD reported. The previous nocturnal record of 27.2°C, set in August 2003, was exceeded by more than two degrees. The nighttime extreme capped a weekend of shattered daytime records: after Friday saw 41.3°C in Saarbrücken and Saturday 41.5°C in Möckern-Drewitz, the mercury climbed to 41.7°C in Neißemünde, Brandenburg on Sunday, marking three all-time highs in as many days.

The heatwave, which the DWD links to a rising frequency of extreme weather driven by climate change, parked a mass of hot Saharan air over Central Europe. Southern winds and föhn effects in Saxony’s uplands amplified overnight temperatures, preventing the usual nocturnal relief. Neighbouring Czech Republic also set a new national record of 41.1°C at Doksany, north of Prague, its meteorological institute said, surpassing a 2012 benchmark. Across the continent, the World Health Organization has attributed more than 1,300 fatalities to the heat.

The impact cascaded beyond thermometers. Emergency rooms across Germany reported a surge in heat-stroke cases, disproportionately among older people. Concrete motorway sections on the A2 buckled, forcing closures. In Saxony, Brandenburg, and Thuringia, forest fires ignited on desiccated terrain, with one blaze near Traisen spreading through an old munitions disposal area, triggering explosions and a full evacuation. Authorities in Prague issued a smog warning, advising vulnerable groups to stay indoors as ground-level ozone spiked.

Cultural and sporting events were cancelled or rescheduled: the Bad Homburg Open tennis final was moved to dawn, and parliament’s dome in Berlin closed to visitors. Environmental officials warned of impending mass fish kills in the Rhine, Moselle, and Saar rivers as water temperatures rose and dissolved oxygen plummeted.

The DWD expects the heat to break on Monday as a band of severe thunderstorms sweeps eastwards, bringing heavy rain, large hail, and gusting winds. Daytime highs are forecast to retreat to 29–32°C. The shift to cooler air will test firefighting efforts and offer a temporary reprieve, but the rapid succession of records has focused attention on the preparedness of central European infrastructure for episodes that meteorologists note are becoming hotter and longer lasting.
