I dove with a wet suit May through October. But last October I bought a dry suit and did about 10 dive over the last winter and it was great. I know I will be using my dry suit year round up here. As they say once you go dry you'll never go back. The best thing is when you take that dry suit off on a windy day and you body is dry. Their is no wrapping yourself up in towels to warm up as you would after striping off a wet suit.
