I am starting a dive club at my high school and need some places where I can plan trips. I talked to my local dive shop and he said in order to get some warm water during the winter months I have to go all the way down to florida. Now this is where I need help. I'm not sure if he meant it was too cold to dive anywhere north of florida without a wetsuit or it was too cold to dive comfortably north of florida. I just got back from some diving in California where I dove in 55 degrees in 7mm suits. Contrary to many opinions I've heard in California I thought the temperature was fine and I was comfortable. So are there dive sites to go to where I could take divers of all skill levels and dive in 7mm wetsuits?
