Wetsuit diving in WI

[Chris H]

Welcome to the board.  Depending on what type of diving you plan to do, you should be able to do numerous dives with a 7mm suit.  I haven't used a wetsuit in a number of years, but in the summer, above the thermocline (typically around 20ft of water) the lakes can get quite warm.  Heck it was 68 in Lake Michigan for a dive or two.  Temperatures below the thermocline can drop quickly, but even then you should still be OK with your suit.  If looking at fish and swimming around is what you are after, you'll have no problems.  If you want to be out on Lake Michigan, you'll still be OK, you'll just want to plan your dive around the temperature and wait until there is a thermocline.
