It was so cool this morning outside compared to my living room which only cooled to 29c overnight. Might be time to look at the window net idea. Suspect that the living room would have cooled down a fair bit more if I had been able to open the windows more at night.
Other rooms are more variable as they get direct sun in mornings or evenings. Normally the living room is coolest but now after days of heat it's warmed up quite a bit. Looks like the worst of the heat is over now though so it should start cooling off. Might open the doors when I get home and contain the cat in the bedroom for a bit.
