As mentioned above, just bring a change of clothes or a towel to sit down on in the truck. Wear long fishing pants (jellyfish protection, and helps keep sand/mud/shells out of the wading boots when tucked into the boot) I prefer the Simms pants that Academy put's on sale from time to time, and I swear by GameGuard fishing shirts (they are the coolest, dry the quickest, blood washes out of them without any scrubbing or spot treatment, and last a long time). With a dry fit material underwear, sandals and the clothes mentioned above, you will almost be completely dry by the time you load the boat/kayak/plastic banana float and put your gear up.
Waders are a definite no this time of year, heat exhaustion and heat stroke are real things.
I say we fish 5 days a week and work 2.
