Predicting First Frost: Average Dates and What They Mean for Your Garden

Predicting the first frost date is tricky. While it doesn't cause the panic of a late spring frost, the first fall frost matters to many gardeners.

Weather scientists have kept detailed frost records for our area. Using 32°F as a reference point (though frost may not occur exactly at that air temperature), the average first frost date is November 13. The earliest was October 25; the latest December 6.

Severe Cold

Using 16°F as the mark of severe cold, records show a 90% chance of occurrence before December 25 each year. In spring, the average date for 16°F is February 5, with the latest occurrence in 30 years being March 4.
