wetsuit diving in winter....

[LKunze]

There are a few factors involved in determining how cold one gets on a dive.  I remember when I was very new to diving and started in a wetsuit my tolerance to cold was actually better than it is now.  The reason, because I wasn't as relaxed early on and my dive skills weren't that great yet.  I was actually exerting more energy and generating more body heat in the process.  Once I became more proficient with my buoyancy skills, learned to frog kick which improved my air consumption and helped me relax, my tolerance to cold went way down.  Another factor is how long your dives are.  There will be a huge difference in how you feel comparing say a 30 minute dive to a 60 minute dive.
