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.

What these dates mean

The cautious fall date for finishing the harvest in the Greenville area is November 1, when there is only a 10 % chance that a light frost has arrived. A hard frost at 28 °F can damage plants that survive a light frost at 32 °F, so it is a more severe risk.

The 50% date is March 18, meaning a gardener faces an even chance of a light frost later in spring, while the 50% date is November 16 gives an even chance of a light frost earlier in fall. For a cautious plan, tender crops should be set out after the April 6 date in spring and should be harvested by the November 1 date in fall. The hard-frost 50% dates are March 4 in spring and November 28 in fall, marking the median points for a 28 °F frost.

How to read the probabilities

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

  • Spring: "10% after April 6" 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 November 1" 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.
