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

May 12 is the cautious spring light-frost date for Raymond; there is only a 10 % chance of a frost occurring after that day, so tender crops can be set out with relatively low risk. The early-spring gamble of April 1 carries a 90 % chance of frost, while the median April 26 marks the 50 % date, meaning there is a 50 % chance of a frost later than this date.

In the autumn the cautious light-frost date is October 1, when only a 10 % chance exists that a frost has already arrived, allowing growers to finish harvesting tender crops. The 50 % date of October 17 indicates an even chance of a frost earlier than that day, and the hard-frost median dates are March 27 in spring and November 7 in fall.

Hard frost at 28 °F can damage plants that survive a light frost at 32 °F, making it the more critical threshold for garden planning.

How to read the probabilities

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

  • Spring: "10% after May 12" 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 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.
