Better late than never !
During last "heatwave" earlier this year, frozen Ice Packs & Reusable ice cubes were the order of the day, along with chilled drinks in a picnic bag.
I forgot to do this, this week. !
So a quick trip to freezer, and all is restored, for later in the night....
A couple of half empty plastic drinks bottles, laid on side, in freezer, nice cold drink as they thaw. Ice only half side of bottle, so you can pour drink out.
Curtains have been effective at keeping heat out day time.
