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 cautious spring date in Aspermont is April 18, when there is only a 10 % chance of a frost after it, so a gardener will wait until that date to begin planting tender crops. The typical date, March 29, carries a 50 % chance of a frost after it, indicating the midpoint of uncertainty. Planting before the early date of March 8, which has a 90 % chance of a frost after it, would be a gamble.

For the fall season, the cautious date is October 25, with a 10 % chance of a frost before it, making it the recommended deadline to finish harvesting tender crops. The typical date, November 7, reflects a 50 % chance of a frost before it, while counting on crops through the late date of November 24, which has a 90 % chance of a frost before it, would be risky.

A hard frost at 28 °F is more damaging than a light frost at 32 °F because the lower temperature can kill plants that survive the milder 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 18" 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 25" 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.
