What kind of wetsuit do people usually use?
This depends much on your own tolerence level. Many divers don’t wear any wetsuit at all, but risk the possibility of being stung by organisms in the water like floating hydroids, tiny jellyfish, or stinging larvae. A lycra skin helps but doesn’t add warmth. If you are planning to do multiple dives, you might consider a Polartek or 2-3 ml neoprene full wetsuit or shortie. For night dives you’ll be more comfortable in a warmer suit. Divers who tend to get cold more easily may go as far as a 5 ml neoprene suit. Keep in mind that the more neoprene you wear, the more weight you’ll need to carry. With the water temperature averaging around 80-82 degrees, and dives lasting as long as 50-60 minutes in some cases you may decide that you want to rent a shortie because what you brought with you is too much or too little.
