I forgot to add.... that this is in Maine. I did my open water cert. in Rockland harbor(hence the freezing point below 32 in salt water), and there was ice on part of it! We pushed ice getting in at the little beach. I made a down payment on my dry suit the day I got certified! I only made two wetsuit dives before I got a drysuit. Even in the summer here the ocean only gets to about the low sixties. OH, if you are diving a wetsuit, carry a big themos of luke warm water to pour into your suit, gloves and booties before you hop in. DON'T USE HOT WATER!!!! It really helps. Also a great warm up after the dive.
