Frying in Berlin: Scorching Summer Hits the City
Berlin's summer this year was nothing short of a heatwave, breaking records and leaving residents dripping in sweat. The mercury averaged a blistering 19.7°C, positioning the city as the hottest German state as per preliminary figures from the German Weather Service (DWD). That's a whopping 1.9°C warmer than the norm for the 1961-1990 reference period.
June and August were bone-dry, but the rainfall clocked in at a respectable 185 liters per square meter. Berlin also took the top spot for sunshine hours, basking in 780 hours, a substantial increase from the typical 664 hours.
Across the country, summer was sweltering, with an average temperature of 18.5°C, bumping up the old record by 2.2 degrees. Although no records were shattered, DWD still declared it as "the 28th consecutive summer of record-breaking warmth." The latter half of the summer saw temperatures soaring, marking a significant departure from the early cooler months.
Despite the blazing heat, occasional rain showers provided a momentary reprieve. The city's weather was a whimsical medley of sizzling heat and rain, a stark change from the usual extended sunshine.
