I was lucky enough to experience the freezing cold OCS (winter in Newport), along with the blistering hot OCS (Summer in Pensacola).
Let me tell you friends, the level of suckage is equal. Winter in Newport was awful.... PT outside, work up a sweat under those sweatpants, etc. Your PT gear gets soaking wet from rolling around on the dewy grass... Sweat soaks it the rest of the way.... Then you stand outside of the chow hall. The layer of moisture under all of your sweats turn to supercooled water droplets (you'll learn about this in API). This makes you in turn, colder. And you have the jackoff in the front that screws up the DISCIPLINE DITY, prolonging your misery. Although the chow hall is luke warm (kept from being toasty due to the door being propped open from classes entering). You are in there just long enough to get that skin adhered moisture above freezing, and are then headed back outside.....
Ahh yes, and Pensacola. Your star jumper / bear crawling precession from the PT field is now over. You are drenched with sweat, morning dew, and the good ole' Florida humidity. As you stand outside of the chow hall, it feels like you are in a sauna with a parka on. Luckily enough, there are about 65 thousand-billion (yes, google that number) knats that just woke up and have worked up quite a thirst for this excessive moisture. Oddly enough, they are mostly attracted to your eyeballs, inside of your nose, and ear canal. If you open your mouth, you'll get at least 5-10 in there as well. You stood outside of the chow hall as dozens of these tiny creatures go spelunking in every exposed orfice. Finally your 30 minute wait is over, until the guy in the front screws up the DISCIPLINE dity. It's hard to not flinch or look like a chinaman with these things landing in your eyes... It itches like crazy... Feels like you are being torturously tickled with dozens of feathers... But you can't move/flinch or else the class will pay....
Good times.... Point is, OCS is OCS. There is no comfortable time to go through.
