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

November 5 marks the cautious fall date for finishing the harvest in Yazoo City, where there is only a 10 % chance that a light frost has arrived earlier. Tender crops held until that date face a low risk of frost damage, while waiting until the later November 24 50 % date brings a balanced chance of an early frost.

In spring, the cautious date for setting out tender crops is March 25, which carries a 10 % chance of a light frost occurring later. The 50 % date of March 4 indicates an even likelihood of a light frost occurring after that point, and the hard-frost 50 % date of February 15 signals a fifty-fifty chance of temperatures dropping to 28 °F.

A hard frost at 28 °F can damage plants that survive a light frost at 32 °F, making it a more critical threshold for growers.

How to read the probabilities

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

  • Spring: "10% after March 25" 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 5" 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.
