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

Planting tender crops on the early spring date of March 28 in the Huntington area carries a 90% chance of a light frost later that season, making it a gamble for growers.

A cautious schedule uses the May 3 date, which has only a 10% chance of a frost later, for setting out tender crops, and the October 13 date, with a 10% chance of a frost earlier, to finish harvesting. The 50% dates—April 14 in spring and October 26 in fall—represent the point where a light frost is equally likely to occur before or after, giving growers a midpoint reference. Hard-frost milestones, March 31 and November 5, are noted because temperatures of 28 °F can damage plants more severely than the 32 °F light-frost threshold. The interval between the two 32 °F 50% dates spans 195 days, based on a 30-year record, giving a sense of the typical season length.

How to read the probabilities

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

  • Spring: "10% after May 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 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.
