Even though astronomers use the autumnal equinox as the marker for the official start of fall, climatologists use September 1.  Historically it made calculations a lot easier and better represents the transition from the three hottest months to the cooler fall.  And just in time comes some cooler weather, which you should see in the next few days once the excitement of Hurricane Hermine passes.  So think cool thoughts and welcome to fall!
