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 27 is the cautious spring date, with only a 10 % chance of a light frost later; it lets a gardener set out tender crops with relatively low risk. Planting on March 30 carries a 90 % chance of frost and is a gamble, while the 50 % date is April 13, meaning a 50 % chance of frost later than that date.

In the fall, October 14 serves as the cautious date, offering a 10 % chance that a light frost has arrived earlier and allowing the final harvest of tender crops. Waiting until November 9 would involve a 90 % chance of frost and is risky, and the 50 % date is October 28, indicating an even odds of frost earlier than that point.

The 50 % hard-frost date is April 3 in spring and November 5 in fall; hard frost at 28 °F can kill plants that would otherwise survive a light frost at 32 °F.

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 14" 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.
