Is this August?

Did the months get mixed up?
August temperatures in central Illinois are usually in the 90's during the day with 90+% humidity, with temperatures dropping into the 70's at night. But the past week or so we have enjoyed daytime temperatures in the low 80's with low humidity, and temperatures dropping into the 60's at night. Beautiful days. The yards are still green and the fields are lush.
Definitely not the dog days so far.
