The dates listed are normal averages for a light freeze. The possibility of a frost occurring after the spring dates and before the fall dates is 50 percent.

A "light freeze" is 29 to 32 degrees F, which kills tender plants killed, with little destructive effect on other vegetation.

Frost dates are used by gardeners to determine what to plant when. Arkansas contains USDA Hardiness zone 6b to 8a, with extreme northern Arkansas being 6a and southern Arkansas being 8a. Little Rock is USDA hardiness zone 7b. More on hardiness zones.
