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 is the cautious fall date in Corinth for finishing the harvest, when there is only a 10% chance a light frost has arrived. For a gardener, the 50% dates signal an even likelihood of a light frost occurring later in spring or earlier in fall. The 50% fall date, November 1, marks an even chance that a light frost will occur earlier, while November 15 carries a 90% chance of a frost already being present, making it a gamble for tender crops. The hard-frost median date for fall is November 11, a reference point for the more severe 28 °F threshold.

In spring the cautious date for setting out tender crops is April 17, which carries a 10% chance of a frost later than that day; the 50% spring date is April 2, and March 16 bears a 90% chance of a frost later, a gamble for early planting. The hard-frost median date for spring is March 20. A hard frost at 28 °F can damage plants that survive a 32 °F light frost, so it matters more.

How to read the probabilities

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

  • Spring: "10% after April 17" 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.
