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

Setting out tender crops on March 1 in Verona carries a 90% chance of a light frost later that season, making it a gamble for gardeners. The cautious spring date for tender crops is April 6, when the probability of a frost later in the season drops to 10%.

The 50% dates—March 21 in spring and November 9 in fall—represent the point at which a light frost has an even chance of occurring later (spring) or earlier (fall). For a cautious fall plan, October 27 marks the date with only a 10% chance that a frost has arrived earlier. A hard frost at 28 °F, shown by the median dates March 6 and November 23, can damage plants more severely than a light frost at 32 °F. The record spans 28 years.

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 October 27" 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.
