Third extended heat wave within 6 weeks.
The previous one exceeded 40°C, and the buildings not yet had time to completely cool down from that one before the third wave hit.
I was considering putting up a tent in my garden myself, but as I own a ground floor flat, the indoor temperatures did, with the help of some additional cooling measures, thankfully not exceeded 27°C.
Still not enough in some cases. My bedroom for example. It's on the southside of the building and even with every window open and fans running till late in the night, I can still feel the temperature difference between north and south side rooms.
