"Frost" and Freeze Dates

 

The fall of 2016 has been warm across the Mid-South. Across the Mid-South at our climate sites; Jackson, Tennessee, had the lowest temperature this fall on October 22 of 36 degrees. Depending on the moisture that morning there may have been a frost. Most other places in the Mid-South haven't been below 40 degrees.
In looking at past data we are just about the point in the year were locations are seeing their average time for the first freeze, yet many haven't even had temperatures in the 30s yet. So here is a look at typical "frost" and freeze dates for the climate sites in the Mid-South.

Here are the earliest and latest "frost" and freeze dates along with the average date for the first "frost" or freeze in the fall and the last "frost" or freeze date in the spring.

  • The freeze date is the date of the minimum temperature being 32 degrees Fahrenheit or below.
  • The "frost" date is the date of the minimum temperature being 36 degrees Fahrenheit or below. Note: Frost is also dependent on moisture so this "frost" date is just an estimate.
