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

April 14 is the cautious spring date, giving a gardener the confidence to set out tender crops after the risk of a light frost has dropped to 10 %.

The 50% light-frost date is March 26, a 50 % chance of a frost later than this date, while the 50% hard-frost date is March 12, a 50 % chance of a hard frost later than this date. The cautious fall date is October 25, indicating only a 10 % chance that a light frost has arrived earlier, so finishing tender-crop harvest by then keeps risk low. The station’s 29-year record shows the frost-free interval between the two 32 °F 50% dates spans 228 days, providing a long growing window.

A hard frost at 28 °F can damage plants that would survive a light frost 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 April 14" 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 25" 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.
