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

In Floydada there are 208 days between the 32 °F 50% dates, a period that brackets the time when temperatures are most likely to remain above light-frost levels. The spring 50% date is April 7 and the fall 50% date is November 3; these dates represent an even chance of a light frost occurring later in spring or earlier in fall, but they are not themselves frost dates. A cautious spring plan uses the April 23 date, which carries only a 10 % chance of a frost later, while a cautious fall plan relies on October 20, which carries only a 10 % chance of a frost earlier.

The hard-frost 50% dates are March 28 and November 12, and a hard frost at 28 °F can damage plants that would survive a light frost at 32 °F.

How to read the probabilities

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

  • Spring: "10% after April 23" 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 20" 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.
