I live in a similar climate to you, so I can sympathize. I went in early December one year and found it to be extremely cold when I wasn't moving around at night. I basically wore all the warm clothes I owned - leggings with jeans, thick socks, a thermal-type shirt with two hoodies over it, a hat and gloves, and I was still chilly. But that's when we were sitting still at night (waiting for parades and the like). When we were walking around I could take off the hat, gloves, and second hoodie. During the day I just needed a light jacket.
