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

Setting out tender crops on March 24 in West Point carries a 90 % chance of a frost later that spring, making it a gamble for any gardener. By contrast, April 21 is the cautious date for setting out tender crops, with only a 10 % chance of a frost occurring later.

The 50 % dates mark the point of even odds: April 6 is the median light-frost date in spring and November 1 is the median light-frost date in fall, so a gardener should expect a frost to be equally likely on either side of those days. The median hard-frost dates are March 27 in spring and November 11 in fall; hard frosts (28 °F) can damage plants more severely than light frosts (32 °F). October 20 is the cautious date to finish harvesting tender crops, with just a 10 % chance that a frost has already arrived.

The 30-year record shows 208 days between the two 32 °F 50 % dates, illustrating the typical frost-free window for this location.

How to read the probabilities

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

  • Spring: "10% after April 21" 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.
