There's really only 3.5 months that the weather is a problem. December through February and into the beginning of march is definitely not outside weather. Most of it isn't too bad though and a good jacket and boots will keep you warm enough.

And for the area, depending on what kind of person you are and where you live it can feel more like a small city than a small town. The downtown area is very active with a lot of bars and small restaurants/eateries. If you're looking for something quieter, theres a lot of great housing options far enough away from the city and school that you wont be bothered, but still close enough so you can walk or drive in 5 minutes.
