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 the early spring date, March 22, carries a 90% chance of a frost later that season. The cautious alternative is April 24, when only a 10% chance remains. The 50% date in spring is April 7; it marks the point where the likelihood of a frost later is even.

In the fall, the cautious date for finishing tender crops is October 13, with a 10% chance that a frost has already arrived, while a gamble would wait until November 10, when a 90% chance of an earlier frost exists. The 50% date in fall is October 27, indicating even odds of a frost earlier. The 50% hard-frost dates are March 29 in spring and November 5 in fall, showing when a 28°F frost is as likely as not. Hard frost at 28°F can damage plants more severely than a light frost at 32°F because it reaches lower temperatures.

How to read the probabilities

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

  • Spring: "10% after April 24" 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 13" 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.
