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

The cautious fall date for finishing the harvest in Dallas (Love Field) is November 10, when there is only a 10 % chance that a light frost has arrived earlier. For a spring start of tender crops, the cautious date is March 19, which carries a 10 % chance of a light frost later than that day.

The 50 % dates give gardeners a neutral point of reference: March 2 is the 50 % date for light frost in spring, meaning there is an even chance of a frost occurring later, while November 29 is the 50 % date for light frost in fall, with an even chance of a frost occurring earlier. The hard-frost (28 °F) median dates are February 18 in spring and December 12 in fall; these lower-temperature events can damage plants that survive a 32 °F light frost, making them a more serious risk.

Using the cautious dates helps keep the probability of frost damage to around ten percent, while the 50 % dates simply mark the midpoint of the historic frost probability curve.

How to read the probabilities

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

  • Spring: "10% after March 19" 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 10" 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.
