Yeah, we can't fly IC at our field before 9 am, so during the summer I pretty much get there a 8:45, and as soon as it hits 9 I'm flying, get a couple of flights and go home. It was in the 100s all last week and was miserable, even at 9. By ten I'm packed up and heading home.

I always make sure to wear a hat to shade my eyes and head and also bring a big jug of water with me. Even just standing for an hour, its easy to sweat off a lot of water, so make sure after each flight you have some water. Also keep your fuel out of the sun if possible, as well as your plane. As covering will start to wrinkle if it gets hot enough.
