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 is October 23, when there is only a 10 % chance of a light frost having arrived.

The 50 % light-frost dates are April 2 in spring and November 4 in fall; at each of these dates the chance of a frost is even. The 50 % hard-frost dates are March 19 in spring and November 17 in fall; these mark the point where a hard frost is equally likely.

A cautious planting schedule therefore uses the April 19 light-frost date for setting out tender crops in spring and the October 23 date for ending their harvest in fall. Hard frost at 28 °F can damage plants that survive a light frost at 32 °F, so it is a more severe threat.

How to read the probabilities

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

  • Spring: "10% after April 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 October 23" 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.
