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

March 27 is the cautious spring date for tender crops in Tyler; with only a 10% chance of a light frost later than that day, a gardener can plan to set out sensitive seedlings. The counterpart cautious fall date is November 4, when there is only a 10% chance of a light frost earlier than that day, marking the latest time to finish harvesting tender produce.

The 50% light-frost date in spring is March 7, a 50% chance of a frost later than this date, and the 50% light-frost date in fall is November 21, a 50% chance of a frost earlier than this date. The 50% hard-frost dates are February 23 in spring and December 4 in fall; a hard frost (28 °F) can damage plants that survive a light frost (32 °F), making it a more critical threshold for growers.

How to read the probabilities

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

  • Spring: "10% after March 27" 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 4" 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.
