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

November 1 is the cautious fall date for finishing the harvest in Paris, Texas, because there is only a 10 % chance that a light frost has arrived earlier. In the spring the cautious date for setting out tender crops is April 2, when the chance of a light frost later is 10 %; planting on February 24 would be a gamble with a 90 % chance of frost later.

The 50% date for light frost is March 14, meaning an even chance of a frost later than this date, and the 50% date in fall is November 16, an even chance of a frost earlier. The median hard-frost dates are March 1 and December 1; a hard frost at 28 °F is more severe than a light frost at 32 °F because the lower temperature can affect plants that survive the milder frost. Over the 28-year record the two 32 °F median dates are 247 days apart.

How to read the probabilities

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

  • Spring: "10% after April 2" 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.
