Two charts, because spring and fall answer different questions: in spring, the chance that a frost still comes after a date; in fall, the chance that the first frost has already come before it. NOAA publishes these odds from 10% to 90%, so the lines stop there. ◆ marks the actual date in each recent year.

What these dates mean

April 3 marks the cautious spring date in Brewton, when there is only a 10 % chance of a light frost later; this lets a gardener plan to set out tender crops with minimal risk.

The 50 % dates represent the median odds for frost. The light-frost 50 % date in spring is March 15 and the hard-frost 50 % date is February 28; in fall the light-frost 50 % date is November 15 and the hard-frost 50 % date is November 30. These dates indicate an even chance of a frost occurring after (spring) or before (fall) them. The cautious fall date is October 30, when only a 10 % chance of a light frost has arrived, allowing harvesting of tender crops to be finished with confidence.

A hard frost at 28 °F matters more than a light frost at 32 °F because the lower temperature can cause substantially greater damage to plants.

How to read the probabilities

The dates are probabilities from 30 years of weather, not a forecast for this year.

  • Spring: "10% after April 3" means that in about one spring out of ten a frost still happens after that date. The 90% date is the earliest: a frost after it happens in most years.
  • Fall: "10% before October 30" means that in about one fall out of ten the first frost arrives before that date.
  • 50% is the typical date: half of the years are earlier, half are later.
  • A light frost (32°F) damages tender plants; a hard frost (28°F) also stops most hardy vegetables.
