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

Setting out tender crops on February 23 in Corsicana is a gamble, because there is a 90% chance of a frost later than that date.

The 50% spring light-frost date is March 14, which carries a 50% chance of a frost later than this date, and the 50% fall light-frost date is November 16, which carries a 50% chance of a frost earlier than this date. For a cautious plan, tender crops are best sown after the April 4 date (10% chance of a later frost) and harvested by the November 1 date (10% chance of an earlier frost).

Hard frost at 28 °F can damage plants more severely than light frost at 32 °F; the median hard-frost dates are March 2 in spring and November 28 in fall.

How to read the probabilities

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

  • Spring: "10% after April 4" 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 1" 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.
