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 22 carries a 10% chance of a light frost later than the date, making it the cautious spring date for setting out tender crops. April 5 is the 50% date for spring light frost, meaning there is a 50% chance of a light frost later than this date. The hard-frost 50% date in spring is March 25, a point where a 28 °F frost is equally likely to have occurred or not. These points are based on 25 years of record.

October 19 carries a 10% chance of a light frost earlier than the date, so it is the cautious fall date for finishing harvest of tender crops. November 1 is the 50% date for fall light frost, giving a 50% chance of a light frost earlier than this date, and the hard-frost 50% date in fall is November 10. A hard frost at 28 °F can damage plants that survive a 32 °F light frost, so it is a more critical threshold.

How to read the probabilities

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

  • Spring: "10% after April 22" 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 19" 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.
