It is down to 77, downstairs here. The windows, upstairs and down, are open. Fans are going hard and heavy, but I am about to give the ones down here a few hours off. At 77, the coolest it has been in a week, or three, it feels downright chilly! Sounds crazy, but it is true. Just dropped to 76...
And, having slept with the temperature at 73 upstairs, in my zone even, I had finally cooled off, generally. At this altitude, 73 often feels chilly, especially when wearing summer weight clothing. Two blankets were needed, if happily.
