I'm fair, but due to the high humidity, I usually didn't wear long sleeves or a hat-the humidity makes the sky whitish, and the UV doesn't get through as bad.
I wore short skirts (hey, even if you're a guy-it keeps your legs WAY cooler!) Honestly, I tried to wear as little clothes as possible-thankfully we lived where no one could see us, and I didn't work during the afternoons. In the hot days I got up at 6am, got right out, came in around 10-11, and went back out around an hour before sunDOWN, which leaves a few hours....Even by moonlight occasionally. And yes, try to work in the shade AMAP. My DH also would stay wet-just pour a
milk jug of
water over his head to keep it wet. Be SURE to stay hydrated!!! You sweat a lot there and you HAVE to stay hydrated, cause heat stroke sucks!
Good luck!
