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 3 is the cautious spring light-frost date for the Fort Worth area; it marks the point when only a 10 % chance of a frost later than this date remains, allowing a gardener to set out tender crops with relatively low risk.

The median light-frost dates are March 11 in spring and November 19 in fall, each representing a 50 % chance of a frost occurring on either side of the date. For a cautious plan, the fall light-frost date of November 3—when only a 10 % chance of a frost earlier than this date exists—guides the latest time to finish harvesting tender crops. The 28 °F hard-frost median dates are February 28 in spring and December 1 in fall, indicating when the odds of a hard frost are evenly split.

A hard frost matters more than a light frost because temperatures at 28 °F can damage plant tissue that survives the milder 32 °F light frost.

How to read the probabilities

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

  • Spring: "10% after April 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 November 3" 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.
