I live in northern Michigan, in the northeast Lower Peninsula, and dive frequently with the folks at the Northern Michigan Dive Center. They're located in Cheboygan, at the mouth of the Cheboygan River, with easy access to the Straits of Mackinac Shipwreck Preserve. They have frequent charters to shipwrecks on both the Lake Huron and Lake Michigan side of the Mackinac Bridge. They run a good operation.
Diving in later July and in August will get you warmer surface temps, around the low to mid 70's. At depths of 80-90' and deeper, I haven't seen the temps get much warmer than the low 40's. I dive with a 7mm Bare Velocity wetsuit, with 7mm hood/boots/gloves. Quite a few folks dive dry suits, but I haven't felt the need yet to make the change.
The Straits of Mackinac Shipwreck Preserve website has a bunch of good info, and feel free to ask me any questions you may have about diving in the area. In fact, if you still need a dive buddy when you get up this way, shoot me a message. It's rare that I'll turn down an opportunity to dive.
