Extreme Heat and Record Temperatures Sweep Across Europe in Summer 2026

Europe experienced extreme heat and drought during the summer of 2026, with several countries recording historic temperatures. In Germany, the summer was the second hottest of the century with an average temperature of 19.6 degrees Celsius, surpassed only by figures from 2003. Germany also saw new record highs in Berlin at 39.9 degrees and in Möckern-Drewitz at 41.8 degrees. Switzerland recorded its hottest summer since measurements began, with average temperatures exceeding those of 2003 and a new record of 39.7 degrees in Basel. In Hungary, August 2026 is expected to be the hottest month ever recorded, with an average temperature around 24.8 degrees Celsius. This contributed to the summer being the second hottest in Hungary since 1901, trailing only the record set in 2024.

The extreme weather led to severe drought and environmental impacts. In Switzerland and Germany, many streams dried up and river levels fell, which forced cargo ships on the Rhine to carry reduced loads. France was even more severely affected, with temperatures frequently exceeding 40 degrees in June and July and catastrophic forest fires occurring near Bordeaux. In Germany, an analysis by the Robert Koch Institute suggests the heat may have caused more than 10,000 premature deaths.

Experts attribute these patterns to a combination of weather chance and climate change. Center-right framing emphasizes the role of fossil fuels and greenhouse gases, noting that Switzerland has warmed by roughly 3 degrees since the pre-industrial era. Center framing in Hungary highlights the rapid warming of the Carpathian Basin and mentions that a strong El Niño event may make 2027 the hottest year globally. In Germany, the hot summer and drought are expected to create further inflationary pressure on food production, industrial output, and transportation.
