Grand Traverse Bay ice conditions

Deep, cold, and the least likely of these waters to lock up. Grand Traverse Bay only makes broad ice in genuinely hard winters, and when it does the whitefish and lake trout fishing is worth the wait.

Access areas: Suttons Bay, Bowers Harbor, Elk Rapids, Northport. Temperature record from Traverse City Cherry Capital Airport.

No ice is safe ice. Everything on this site is accumulated weather data and satellite observation. None of it measures the ice under your feet. The Michigan DNR does not recognize a reliable inch thickness rule and states that ice on the bays of the Great Lakes will always be more fragile. Test with a spud bar or auger every few steps, every trip, and read the ice safety page before you go out.

What this water is like

The bay runs several hundred feet deep in places, and deep water holds an enormous amount of heat. That thermal mass means Grand Traverse Bay resists freezing long after shallower water has locked up, and in mild winters the main basin never freezes at all. What does freeze, and freezes first, is the shallow protected water: Suttons Bay, Bowers Harbor, the far south end of the west arm. Those are the traditional ice destinations and they are the only parts worth watching in most years.

Satellite ice cover shown here is for Lake Michigan as a whole, not for this specific water. It is a directional signal about the lake, not a measurement of the ice where you fish.

What to know before you go

Depth resists ice

Several hundred feet of water holds heat. In a mild winter the main basin simply does not freeze, and no amount of cold in December changes that quickly.

The protected pockets go first

Suttons Bay, Bowers Harbor, and the south end of the west arm are where ice forms and where the fishing happens.

Lake wide numbers mislead here

A Lake Michigan cover percentage is dominated by the far north and the shallows elsewhere. It says very little about this specific bay.

The other waters

These six waters behave differently enough that a plan built for one can be wrong on another. Depth, current, and wind exposure all change the picture.
