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

June 4 is the cautious spring date for Indian Lake 2 SW and it allows a gardener to set out tender crops with only a 10% chance of a later light frost. The median light-frost date, May 23, marks the point where a light frost is equally likely to occur before or after, while the median hard-frost date, May 9, indicates when a 28 °F freeze becomes as probable as not.

In the autumn the cautious date is September 12, giving a 10% chance that a light frost has already arrived and signaling when to finish harvesting tender crops. The median light-frost date, September 27, represents even odds for a frost, and the median hard-frost date, October 7, shows when a hard freeze reaches a 50 % likelihood. A hard frost matters more than a light frost because the lower temperature can damage 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 June 4" 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 September 12" 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.
