<p>The most time you’re going to spend outside is maybe 15 minutes at the very most, if you walk relatively quickly to classes. It’s not that big of a deal. Everyone wears t-shirts and whatnot indoors, so it’s really the same thing as home. I’m saying this as a student from NorCal too. I, personally, didn’t find it to be that big of a deal, though I was happy to be out in 60 degree weather yesterday :)</p>
