Average Frost Dates
Courtesy of the National Climatic Data Center, National Oceanic and Atmospheric Administration.
The dates listed above are normal averages for a light freeze/frost. The possibility of a frost occurring after the spring dates and before the fall dates is 50 percent. Frost/freeze temperatures are categorized by their effect on plants:
- Light freeze: 29 degrees F to 32 degrees F – tender plants killed, with little destructive effect on other vegetation.
- Moderate freeze: 25 degrees F to 28 degrees F – widely destructive effect on most vegetation, with heavy damage to fruit blossoms and tender and semi-hardy plants.
- Severe freeze: 24 degrees F and colder – damage to most plants.
*Higher elevations in Hawaii do occasionally see at-or-near freezing temperatures but definitive frost dates are not available.
