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

April 4 is the cautious spring light-frost date, meaning there is only a 10 % chance of a frost later than that day, so a gardener can plan to set out tender crops with minimal risk.

The median light-frost dates are March 14 and November 13; the 50 % chance of a frost later than March 14 and the 50 % chance of a frost earlier than November 13 give a useful reference point for timing. For a cautious fall schedule, the 10 % chance date is November 1, which marks a low risk of a frost having arrived and therefore is the date to finish harvesting tender crops.

Hard frost, defined at 28 °F, is more damaging than a light frost at 32 °F, so the 50 % hard-frost dates of February 28 and November 27 are important markers of when the more severe temperature threshold becomes a 50 % risk.

How to read the probabilities

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

  • Spring: "10% after April 4" 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.
