I had 40 Celsius today at around 9pm. Middle of the night now and it’s 34. It’s as cool as it’s going to get before it starts heating up again tomorrow. Where I live there are no laws on max temperature in residential housing so the owner (I’m renting) doesn’t have to do anything about it. Never mind the poorly insulated, black slate roof (I’m on the last floor) or lack of AC (I’d have to foot the bill anyway).
Last summer my house got to 39, and I didn't have AC (it was broken). I think I'm still recovering.
