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 240 days between Cleburne’s 32°F 50% dates, March 17 and November 12, mark the interval when light frosts are as likely to have occurred as not. For a gardener, the spring 50% date signals an even-odds point for a light frost occurring later, and the fall 50% date signals an even-odds point for a light frost occurring earlier.

The cautious spring date for setting out tender crops is April 6, when there is only a 10% chance of a light frost later; the cautious fall date to finish harvesting tender crops is October 30, when there is only a 10% chance of a light frost earlier. Hard frosts at 28°F, indicated by the median dates March 6 and November 25, can damage plants that survive a 32°F light frost, so those hard-frost dates matter more than the light-frost dates.

How to read the probabilities

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

  • Spring: "10% after April 6" 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 30" 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.
