It’s all about wrecks when diving in Michigan. Thunder Bay, home to over 100 wrecks is a national marine sanctuary with gem’s lying as little as a few inches to 200 feet. Among the most popular is the ‘Montana’, a 235-sidewheel steamer that sunk after a fire.
One of the richest areas in Michigan for wreck diving is the Manitou Passage Underwater Preserve which surrounds the Manitou Islands, part of the Sleeping Bear Dunes National Lakeshore. Wrecks to check out include Francisco Morazan, Three Brothers and Walter L.Frost.
Lake Michigan is also well worth a visit, with over 3000 shipwrecks- all full of unique stories and many dating back to the 1800s.
The recreational dive season in Michigan is from May- November, though it is possible to dive a number of the lakes all year. We recommend you contacting the lakes locally when planning a dive and also make sure you are certified to the level needed to dive the lakes.
At depth, water temperatures can be as high as 68°F/20°C. During the winter months, water temperatures can drop around 32°F/0°C so a 7mm wetsuit is generally sufficient protection for most divers June- October but during the colder months, a dry suit with thermal garments and redundant air supply are required.
Visibility can vary from day to day and from lake to lake. At times visibility can exceed 100 feet/ 30 meters, but generally divers will find visibility at about 35-40 feet/ 10-12 meters.
