Yes, I was there on Jan 3. Water was a bit cooler than usual but still pleasant - Probably in very high 70's. I wore a 3mm full length with skins and hood and was very comfortable. Many were wearing just a 3 mm shorty and seem to do ok. December is usually Belize's coldest month and the water gradually warms in January. I would suggest a full length 3 mm if you have one.
