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

October 20 marks the cautious fall date for finishing the harvest of tender crops in Cedartown; there is only a 10 % chance that a light frost has arrived before then.

In spring, the cautious date for setting out tender crops is April 14, when a light frost is still only a 10 % possibility later in the season; the 90 % gamble date is March 8. The 50 % date, March 30, indicates the point at which a light frost is equally likely to occur later or not, giving gardeners a statistical midpoint for planning. For the end of the season, the fall cautious date is October 20 and the 50 % date is November 4, marking the moment when a light frost is as likely to have arrived earlier as not.

Hard frost, defined at 28 °F, is more consequential than a light frost because plants that can survive 32 °F may still be damaged when temperatures drop to 28 °F; the 50 % hard-frost dates are March 16 in spring and November 15 in fall.

How to read the probabilities

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

  • Spring: "10% after April 14" 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 20" 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.
