Today, a new "national record" for the highest temperature ever recorded in Germany by an official weather station since records began to be kept in the late 19th century was reached: 40.5°C (104.9°F). The old record was 40.3°C (104.5°F) set in 2015. Seems that then so-called "summer of the century" of 2003 is having its records shredded. And this new record may hold for exactly one day, as the peak of the current heat wave is not expected until tomorrow.
Regionally, at 7 PM the temperature was still 35°C (95°F). At 10 PM it was still 29°C (84.2°F). Getting the heat out of our apartment may involve us having to wait until way past midnight before we can open the windows.
EDIT Thursday 25 July:
Yes, yesterday's record was a one-day-wonder. The first weather station to report a higher temperature today did so at 2:20 PM. And the maximum temperatures were mostly reached around 5 PM. Yesterday’s record must be in something like a tie for 30th place in the list of highest temperatures recorded by German weather stations by now.
The new record did not just nudge up the old one like that did the previous one, it pulverized it: 42.6°C (108.7°F).
And regionally, today's 10 PM temperature was 31°C (87.8°F).
