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 8 is the cautious spring date for Edenton, marking the point when there is only a 10% chance of a later light frost and allowing a gardener to plan setting out tender crops.

The 50% chance of a light frost occurs on March 24 in spring and November 14 in fall; at each of these dates there is an even chance of a frost later (spring) or earlier (fall), which marks the halfway point of frost risk. The 50% chance of a hard frost occurs on March 9 and December 1. November 1 is the cautious fall date for finishing tender crops, with only a 10% chance that a light frost has arrived earlier.

A hard frost at 28 °F can damage plants that survive a light frost at 32 °F, so the hard-frost dates represent a stricter threshold for winter risk.

How to read the probabilities

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

  • Spring: "10% after April 8" 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.
