It cooled off for a few days and then we had a rainstorm. SLowly the temps are creeping back up. Today was comfortably in the 80s, with a few 88-90s days coming up this week.
This will be a good time to do more experimenting with keeping cool. Thus far, a table fan is a must, as well as keeping windows and doors open at night and shut during the day. (at least when the nighttime temps are cool enough to sleep through).
I am also going to mess around with portable window insulating ideas, and using cool washcloths during the day.
