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

May 13 is the cautious spring date for Lebanon, Virginia, and it lets a gardener plan to set out tender crops with only a 10 % chance of a later light frost. The 50% date in spring is April 25, indicating an even odds of a light frost occurring later, while April 10 carries a 90 % chance and is a gamble. The spring hard-frost 50% date is April 13.

In fall, the cautious date to finish harvesting tender crops is October 5, when there is only a 10 % chance that a light frost has arrived earlier. The 50% date in fall is October 16, and October 29 bears a 90 % chance and is a gamble. The fall hard-frost 50% date is October 25. Hard frost at 28 °F can damage plants that survive a light frost at 32 °F. The two 32°F 50% dates are 173 days apart, based on 27 years of record.

How to read the probabilities

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

  • Spring: "10% after May 13" 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 5" 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.
