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.
If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1919, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
