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 12 is the cautious spring date, giving a Stamford gardener only a 10 % chance of a light frost later and allowing tender crops to be set out. The 90 % chance date of March 2 would be a gamble for such crops.

The 50% date is March 23, meaning there is an even chance of a light frost on either side of that day, and the 50% date is November 11 with the same odds in fall. The 50% hard-frost dates are March 8 and November 20, indicating an even chance of temperatures reaching 28 °F around those points. October 28 is the cautious fall date, with only a 10 % chance that a light frost has arrived earlier, so it marks a point to finish harvesting tender crops.

A hard frost at 28 °F can damage plants that survive a light frost at 32 °F, making it a more serious risk.

How to read the probabilities

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

  • Spring: "10% after April 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 28" 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.
