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

The cautious fall date for finishing the harvest in the Augusta area is October 28, when there is only a 10 % chance that a light frost has arrived. In spring the comparable cautious date for setting out tender crops is April 9, which carries a 10 % chance of a frost later than that day.

The 50% date is March 23 for spring light frost and the 50% date is November 9 for fall light frost. Each marks an even chance of a frost later than March 23 and earlier than November 9, so gardeners can use them to gauge the middle of the risk window.

Hard frost at 28 °F can injure plants that survive a light frost at 32 °F, making it a more critical threshold for tender crops.

How to read the probabilities

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

  • Spring: "10% after April 9" 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 28" 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.
