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

October 10 is the cautious fall date to finish harvesting tender crops, reflecting a 10% chance that a light frost has arrived earlier. In spring, May 4 is the cautious date for setting out tender crops, with only a 10% chance of a light frost occurring later.

The 50% date in spring is April 22; there is a 50% chance of a light frost later than this date. The 50% date in fall is October 23; there is a 50% chance of a light frost earlier than this date. The median hard-frost dates are April 11 in spring and November 2 in fall. The 30-year record indicates 182 days separate the two 32°F 50% dates, marking the typical frost-free interval.

Hard frosts at 28°F can damage plants more severely than light frosts at 32°F.

How to read the probabilities

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

  • Spring: "10% after May 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 October 10" 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.
