First & Last Frost Dates of Michigan Cities and Towns

Michigan has different weather zones that affect when frost happens across the state. In Detroit, plants can grow for 198 days, while in Clay Springs, it’s only 144 days. These differences matter a lot for anyone growing plants in Michigan.

Big cities like Detroit, Grand Rapids, and Warren have longer growing times. But places up north or on higher ground, like Traverse City and Gaylord, have shorter growing times. In these areas, the last spring frost might happen in May, and the first fall frost could come as early as September.
