If it stays the same as it has lately......plan for August temps in November. It has been in the high 80s almost every afternoon-even when it rains. We are definitely still having summer weather this year.........but watch to see if cold fronts will try to make it down. I would pack mostly shorts, t's, and your swimsuit. Bring a pair of long pants and light jacket in case it does get down in the 70s at night. Here on the coast we haven't gotten below 75 in almost 200 days now.
