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

The cautious fall date in Jasper for finishing the harvest is October 24, when there is only a 10 % chance that a light frost has arrived earlier. The 50 % date for light frost in fall is November 5, which marks an even chance of a frost occurring earlier, while November 26 carries a 90 % chance and represents a gamble for tender crops.

In spring the 50 % date for light frost is March 31, indicating an even chance of a frost later than that day. The cautious date for setting out tender crops is April 18, with a 10 % chance of a later frost, whereas March 11 carries a 90 % chance and is risky. Hard frosts at 28 °F, noted by the median dates March 17 and November 18, matter more than light frosts because the lower temperature can damage or kill plant tissue that survives a 32 °F frost.

How to read the probabilities

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

  • Spring: "10% after April 18" 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 24" 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.
