Until last year, I wore a 3/2 all winter every winter. I surfed ALL winter (Ing NC for 3 of the past 5 years) but was really really cold alot of days. Finally this past year I got a 4/3 and it has made all the difference and I think this year I'm going 5/4/3. I would definitely not recommend a 3/2 for the winter but if you've got nothing more and no funds to upgrade, it's doable.
