That's because 25.5°C is not anywhere near the peaks we're seeing here. Right now, it's nice and cool, scattered clouds, exactly 25°C outside where I live. Nobody would dream of turning on the AC right now, in fact it would be nice if it could get a little bit warmer and sunnier. When summer was starting out this year, it got to 32°C outside my home in the shadow, but that still wasn't a heat wave. During a heat wave, this rises to the mid thirties, and can in extreme situations approach 40. Lots of unremitting sunlight and stagnant air can drive the actual temperature people experience in cities much higher. Mind you, I'm not arguing that Germany has the most extreme climate on the planet. Yes, you can easily pick a hundred thousand places that are far worse, and you guys in the Deep South are very very tough and all that ;) It's a different thing to argue that in Germany you flat-out don't need air conditioning, especially if you never experienced how bad it can get. But even if this is all just a sign of my own special and extraordinary weakness, I still feel better when I have one.
