Default Day of First Frost

It is quite interesting to see the difference in the date of first frost in Michigan. This determines the growing season and which plants can survive in the area.

Here is a first frost map:



The link below may be a more accurate first frost map:

Michigan Interactive First Frost Map

There are "warm" spots near St. Joe and South Haven, and in the Detroit-Port Huron area.

There are cold spots near Gaylord and west of Marquette. There is a huge difference in the length of the growing season.



This is amazing that there is such a big difference in the growing season, with St. Joe and Detroit having more than 180 days, and west of Marquette having less than 60!

Here is a table of first frost dates:

It looks like Watersmeet wins the first frost award, with a 10% chance of first frost on August 12!

Looking over the map of the growing season, where I'm located on the map, I would be just inside the bottom "pink" part of the state, & the length of growing season sounds about right, since pumpkins & squash can be picked in the Fall.

We are not far away from having frost, this early A.M. it was 41* & that was around 8:00 a.m.

Detroit has 150 days between first (Oct 9) and last (May 12) frost, so Im unsure of why the dot of 180+ days, although there is a difference between a freeze (32 or lower) and frost (which can be mid-upper 30s), and we do see that often times in the Fall. The suburbs will have numerous freezes before Detroits first.

Elevation and distance from the water.

Interestingly, our maps here in CA work the same. You can go from a frost free area to an Aug / Sept frost area over an incredibly short distance.
