How do I survive Band Camp?

Ok, so I start band camp tomorrow (July 1st) and I need to know how to survive the heat. Im from Colorado so that is where my body has adapted to live, But I now live in South Carolina. I have band camp like all day long until like September so does anyone have any knowledge of how to survive SC heat? If you aren't from here you have no idea. The humidity is almost always 100% and it is like 97 degrees everyday. How do I survive? Thanks!
