I came to USNA from Iowa. I had farm-labor summer jobs - swinging bales, detassling corn - and I was outdoors 10-16 hours a day in heat, humidty, and rain. On top of that, have you ever been in a cornfield in the summer? It really is a sauna. Despite that, plebe summer in Annapolis was really nothing like a humid Iowa day in a cornfield. Here's the thing, though: human beings can adjust to almost any climatic factors. It doesn't mean you have to like it, but you can and will learn to tolerate and even thrive in any climate. You will take clothing cues from upperclassmen and classmates who grew up in upstate NY, New England, and the upper Midwest, and in turn, you can help your classmates from Alaska and western states adjust to the humidity you're so used-to. Tens of thousands of people have done it and you can do it too. And, long after you graduate and commission from West Point, when you PCS from Fort Drum to Fort Polk to Camp Humphreys, you'll probably start to realize that you can handle anything the Army throws at you, which can only make you a better soldier and leader.
