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.
I once lived in a basement one room suite, so no balcony or any outdoor space. During the summer it was hotter than the outside. I remember lying down in the bathtub running pure cold water to cool down, then trying to sleep for a bit but having to repeat cooling off every 2 hours.
Basements are usually cooler unless theres a very inefficient furnace/boiler situation.
Must’ve been something like that. I was next door to the boiler room.
