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

The 230 days between the 32°F 50% dates, March 21 and November 6, frame the period when light frosts are less likely to dominate. For a gardener these dates are the median points where a light frost carries a 50% chance of having occurred, serving as reference markers rather than frost dates themselves. In spring the cautious date for setting out tender crops is April 7, which carries only a 10% chance of a later frost, while planting on March 2 involves a 90% chance and is a gamble. In fall the cautious date to finish harvesting tender crops is October 24, with a 10% chance that a frost has arrived earlier, whereas waiting until November 25 means accepting a 90% chance of an earlier frost. The hard-frost median dates are March 6 and November 19, and a hard frost can damage plants more severely than 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 7" 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 24" 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.
