I would advise you to keep a close eye on the temp, and the sunshine factor if you end up wearing a full wetsuit. If the weather is sunny and warm, I would hold off on donning, and zipping the upper portion of the suit until right before your start wave. As I’m sure you’ve experienced, a full wetsuit in the sunshine is like having an electric blanket on. If you put the wetsuit on too early, you’ll begin to perspire, and the potential of heat exhausting that much closer. Good luck. — Dan
