Same here...we do August as a regular even tnow it seems....free dining upgrade is too good to pass up.
I posted with others in a long thread how to manage August a few months ago. Perhaps you could find it as it had all the right tips and tricks (managin time, get to park at opening, take mid-day break, use misters, etc.) Bottom line...
It is HOT
...but manageable, even enjoyable, if approached right.
