How the chance of frost changes with the date

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.

What these dates mean

The cautious fall date for finishing the harvest in Lamesa is October 22, when there is only a 10 % chance that a light frost has arrived.

In spring the cautious light-frost date is April 22, the point at which tender crops can be set out with just a 10 % chance of frost later. The 50% light-frost date in spring is April 4, meaning a 50 % chance of a frost later than this date, and the 50% light-frost date in fall is November 4, meaning a 50 % chance of a frost earlier than this date. The median hard-frost dates are March 19 and November 13. The 90 % risk dates are March 16 for a gamble in spring and November 15 for a gamble in fall.

A hard frost at 28 °F is more damaging than a light frost at 32 °F because it can kill tissue that survives milder freezing.

How to read the probabilities

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

  • Spring: "10% after April 22" 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 22" 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.
