I am relatively new to the surfing scene in Delmarva and had a few surfing equipment related questions.

First, at what point does the water get warm enough to start using a lighter wetsuit and eventually no wetsuit at all? Is it typical that most surfers use their winter wetsuits (4/3 or greater) till the water gets warm enough to move to board shorts and a rash guard instead of buying a lighter wetsuit.

Also, is there a typical time during the year when surfboards go on sale and prices are the best?
