This week in Lembongan… Another busy week on our little island. We have had two full boats going out every day. Temperatures in the south of the island have dropped and our divers were happy that we rent out 5mm full wetsuits to keep them warm and cozy. We all like to wear wetsuits nowadays for diving. But how does a wetsuit really keep you warm? Most wetsuits are made from multiple layers—and these help to trap and reflect heat much like any other insulating clothes. Some are lined with a thin layer of metal such as titanium or copper to reflect your body heat back inside. That helps to keep you even warmer than a normal wetsuit. Also, as you step into the ocean, a small amount of water seeps in between the neoprene costume and your skin—and stays there. Your body quickly warms this water up to something approaching normal body temperature. So now, between you and the sea, there’s an insulating layer of rubbery material, some warm water, and multiple layers of insulation—all working together like a kind of personal, all-over body radiator! This is why it is important that a wetsuit fits properly. If it is too loose the water that is warmed up by your body will escape and be replaced by colder water cooling down your body. So always make sure that your wetsuit fits properly.
The currents around Nusa Penida and Lembongan can be quite strong at times. We experienced that again this week when our divers were able to drift along our beautiful reefs and enjoy the vast variety of marine life. Our guides are always keeping an eye out in the blue just in case a Mola or other big fish decides to make an appearance and this week quite a few of our divers were lucky to see a Mola.
