At the moment SWMBO is pulling down all the blinds in the house during the daytime. Then c. 7pm every window get's fully opened however it was still 26 degrees in the bedroom when we went to bed last night. When I got up at 5am the bedroom was at 19 degrees - still too hot. Spent the night ON the covers with bum in the air. On the rowing machine in the barn with a cement board roof it was a bit hot as well I can tell you!
Rumour has it that July is set to be the hottest ever... however that might have been a scare story from the Daily Mail so that's probably total 'below the belt'.
