I echo @fakeinternetnews "oh dude!" I lived in Pensacola for 10 years and went through OCS in the summer there. Believe me, it was already muggy and warm when we mustered for PT at 0530 and by 7 AM when the sun was up and we were going to chow, it was freaking miserable in light PT gear. Marching a couple blocks in washed khakis left us pouring sweat, so I can't begin to imagine a suit, and I don't imagine New Orleans would be any better than Pcola.
