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 April 2 in Painesville bears a 90% chance of a light frost later that season, making it a high-risk gamble. The cautious date is April 27, when only a 10% chance of a later light frost remains, giving growers a much lower risk for tender plantings.

For a gardener, the 50% date is April 15, which carries a 50% chance of a light frost later than this date, while the 50% date is November 9, which carries a 50% chance of a light frost earlier than this date. The hard-frost median dates are April 4 and November 21; a 28°F hard frost can injure or kill tender crops more readily than a 32°F light frost. In fall, the cautious date to finish harvesting tender crops is October 30, when only a 10% chance of an earlier light frost exists, whereas waiting until November 25 would involve a 90% chance and a gamble.

How to read the probabilities

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

  • Spring: "10% after April 27" 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 30" 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.
