Full length, lightweight wetsuit/skin – this is required for all dives and snorkels (2 or 3 mm thickness is good – no shorties) To protect you from possible cnidarian stings, we ask you to wear full protection every time you enter the water. The thickness of that protection is up to you. Do you get cold easily? Than a 3 to 5mm wetsuit might be your best option. Are you always hot, even in the winter? In that case you can opt for a lycra skin. Water temperature in summer (July – September) is approximately 86 F, in the winter (November – March) it might drop to 77 F.
