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 3 is the cautious spring date, meaning there is only a ten-percent chance that a light frost will occur later and it allows the setting out of tender crops. Planting before February 24 would be a gamble, since a frost is ninety percent likely later.

A 50 percent chance of a light frost later than March 15 marks the median spring date, and the 50 percent chance of a light frost earlier than November 16 marks the median fall date. The 50 percent hard-frost dates are March 1 in spring and November 29 in fall. For a cautious fall plan, November 1 is the date with a ten-percent chance that a light frost has already arrived, so tender crops can be finished then.

A hard frost at 28 °F can damage plants that would 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 3" 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 November 1" 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.
