I have a portable air con unit upstairs, it tells me the room temperature when I turn it on.
Last night it said 40c.
40!!!
And honestly the aircon only really took the edge off. Left on all night and it only got down to 29c.
Our house is a sauna in the Summer and cold in the Winter. Bet you can guess which season I prefer!
Poor children in this heat. Wet hair and fans seem to help.
