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

August 30 is the cautious fall date for finishing the harvest of tender crops at Gibbs Ranch – Jarbidge 24 SE, because only a 10 % chance of a light frost occurs earlier. In spring the cautious date for setting out tender crops is June 20, when a light frost later in the season also carries a 10 % chance.

The 50 % dates mark the point at which a light frost has a 50 % chance of occurring later in spring on June 4 and earlier in fall on September 15; they are not frost dates themselves. For hard frosts the median dates are May 16 in spring and September 27 in fall, indicating a 50 % chance of a 28 °F frost later or earlier. A hard frost matters more than a light frost because temperatures of 28 °F can damage plant tissue that would survive the milder 32 °F conditions.

How to read the probabilities

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

  • Spring: "10% after June 20" 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 August 30" 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.
