What these dates mean
May 16, with only a 10% chance of a later light frost, is the cautious date for setting out tender crops in New Lexington. By waiting until that day, a gardener can plant sensitive seedlings with a low risk of a spring frost interrupting growth.
The 50% light-frost dates are April 30 in spring and October 17 in fall; at each of these points the chance of a frost is even, so they mark the median of the historic record. The 50% hard-frost dates are April 19 and October 28, indicating when a 28 °F frost is as likely as not. For a conservative schedule the fall cautious date is October 4, when there is only a 10% chance that a light frost has arrived earlier, allowing tender crops to be harvested safely. A hard frost at 28 °F can injure plants that would survive a 32 °F light frost, making those dates particularly important for protecting crops.
How to read the probabilities
The dates are probabilities from 30 years of weather, not a forecast for this year.
- Spring: "10% after May 16" 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 4" 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.
