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 at Midville Experiment Station, meaning there is only a 10 % chance of a frost later than that day and it lets a gardener plan to set out tender crops with minimal risk. By contrast, the February 27 date carries a 90 % chance of a frost later, so planting then would be a gamble. The 50 % date, March 18, marks the point at which the odds of a frost later are even; a gardener can use it as a reference for when the risk begins to rise.

In the fall the cautious light-frost date is October 28, when there is only a 10 % chance of a frost earlier than that day, allowing a gardener to finish harvesting tender crops before frost is likely. The 50 % date, November 11, signals equal odds of a frost earlier. A hard frost (28 °F) has separate 50 % dates—March 4 in spring and November 26 in fall—and matters more because temperatures that low can damage plant tissue that survives a light 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 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 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.
