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.

What these dates mean

March 22 is the cautious spring date for light frost (32 °F) and it lets a gardener set out tender crops with only a 10 % chance of a later frost. The earlier spring date, February 13, carries a 90 % chance of frost and is a gamble for tender crops.

The 50% date is March 5, meaning there is a 50 % chance of a frost later than this date, while the 50% date in fall is November 24, indicating a 50 % chance of a frost earlier than this date. For a cautious fall plan the November 6 date is used, offering only a 10 % chance that frost has already arrived, allowing the gardener to finish harvesting tender crops. The 50% hard-frost dates are February 21 and December 7.

A hard frost at 28 °F can damage plants that survive a light frost at 32 °F, so it matters more for garden safety.

How to read the probabilities

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

  • Spring: "10% after March 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 November 6" 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.
