Source: NOAA National Centers for Environmental Information (NCEI), U.S. Climate Normals 1991–2020, annual/seasonal freeze-date probabilities (32°F, 50% probability). Station-level medians; your yard may differ.
How to use frost dates
- Spring: the 32°F date is a coin flip. Plant frost-tender crops (tomatoes, peppers, basil) 1–2 weeks after it; hardy crops (peas, spinach) go in 4–6 weeks before.
- Fall: count back from the first fall frost to sow lettuce, spinach, and radishes and to plant garlic and bulbs.
- Microclimates: low spots, valleys, and open rural fields frost later than hillsides and cities.

Frequently asked questions
What does a 50% frost date mean?
It is the date by which, in half of years from 1991–2020, the last spring (or first fall) temperature of 32°F or lower has already occurred. In about half of years there is still a frost after the spring date, so tender plants are safer 1–2 weeks later.
When is the last frost in Hockessin, Delaware?
The nearest NOAA normals station to Hockessin (ZIP 19707) is Avondale 2 N, PA, about 7 miles away, with a median last spring frost of April 19 and first fall frost of October 26.
Why are city frost dates earlier than the suburbs?
Urban heat, bays, and large rivers keep nights warmer. Downtown Baltimore, Philadelphia, and Norfolk stations frost weeks earlier in spring than nearby rural or hilltop stations.
Do frost dates change over time?
NOAA updates normals every decade. The 1991–2020 normals are the current official set; recent springs have trended slightly earlier in many places.
