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

November 6 marks the cautious fall date for Perry, the point when only a 10 % chance exists that a light frost has arrived, so tender crops should be finished harvesting by then. The 50 % date in fall, November 26, represents the median moment when a light frost is equally likely to have occurred earlier or not, giving gardeners a statistical midpoint for planning.

The median light-frost date in spring is March 4; a 50 % chance of a frost later than that date helps gardeners gauge the middle of the risk window. For a cautious spring start, the March 26 date carries only a 10 % chance of frost later, while the February 6 date (90 % chance) is a gamble. The median hard-frost dates are February 17 in spring and December 13 in fall, and a hard frost at 28 °F can damage plants more severely than 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 March 26" 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.
