Uh, Fall themed wedding in August?

My theme is Fall and my wedding is in October-makes sense to me. I just looked at pics from a wedding a friend attended this past Saturday and the theme was also Fall. Fall colors, Fall leaves everywhere for decor. Just seemed odd to me since it's the hottest part of summer here in SC. Made me think of the girl who asked recently about doing a Halloween type wedding in different month than October. I guess if it was a "Beach" theme I wouldn't bat an eye no matter what the month.
