Hi Alvin,
There is quite a bit of diving around Milwaukee. There are 7 or 8 dive shops in the Milwaukee area and more in the cities along the lakeshore. The shops host various dive activities throughout the year. There are a few dive boats that visit the numerous wrecks in Lake Michigan. Some of the wreck dives are very deep and require special mixes and equipment. Certification dives are frequently accomplished in several quarries around the area. Some quarries or inland lakes were developed specifically for divers. The inland water temperatures are around 60-65F near the surface and 50’s deeper. Unless I’m going deep I wear a beanie or cap (not a hood) and wear thin gloves.
Happy Diving,
Ken
