Typical dates have a 50% chance of a frost after them in spring, and before them in fall; safer dates, 10%. A garden can differ from its nearest station, especially in a valley or on a hillside: see why your garden may differ.

Questions

When is the last frost in Michigan?

It depends on where you are. The typical last spring frost at Michigan's NOAA stations ranges from April 17 to June 7, and half of them have had it by May 8. Enter your ZIP code above for the station nearest you.

When is the first frost in Michigan?

Typically between September 9 and November 5, depending on the station; the median is October 11. Plan fall crops back from your own station's date.

What do "typical" and "safer" mean?

With the typical (50%) last-frost date, half of years still have a frost after it. With the safer (10%) date, only one year in ten does. In fall it's the other way around: the safer date is the earlier one.
