Showing 24ºC minimum temp overnight here luckily in 24 hours it'll mostly be over, with windows wide open.Only goes down to 20 in the middle of the night and the house will be radiating all that stored heat so I would be amazed if I can get the bedroom down under 23 overnight.
Worst thing is that you need the windows open to vent it so the curtains are open. Sun wakes you up at an ungodly hour and then everyone on the way to the station seems to love to shout at 7:30 like its a fricking jamboree.
