Being cold on your dive is not much fun, and also increases the risk of decompression sickness. So stay warm and enjoy your dives.
Wetsuit thickness
Having a wetsuit that is suitable to the climate is key. Deciding on your wetsuit thickness should be based on a few variables 1) the water temperature and 2) how much you feel the cold. At this time of the year, I wear a 7/8mm Apeks semi dry and many layers to keep toasty.
Thermal accessories
Sometimes just a wetsuit isn’t enough so you may want to think about some extra layers. Divers lose most of their heat through their head when diving! So, if you find yourself still a bit chilly try a hood or sharkskin undergarment – studies have shown that 7-10% of heat is lost through your head – wouldn’t it make sense to wear a hood?
Adjust your weights
Remember if you change your wetsuit, you will have to adjust your weights. Most people will add 6 pounds when changing from a 5mm to a 7mm suit.
Keep this in mind – you’d rather be slightly over weighted than under weighted.
Still cold?
