My OWC was in a lake in Illinois with water temps around 58-62F and outside temps of 33F. I have an understanding of what the water will be like and the extreme differences between my certification dives versus what I have been recently logging. I have read a lot of concerns by California divers regarding people coming to dive off California's coast who's prior experience is mostly Caribbean. Is it because they weren't expecting the cold water and therefore didn't enjoy the diving? Is it because of Kelp forests and the major differences in environment? I am sure it will be a huge learning experience for us. Thanks for the advice on the wetsuits!
