Did You Know?: Frost and Freeze Information
When will fall allergy sufferers get relief? Weed season can last until a hard freeze happens. Here is information that explains frost and freeze conditions.
Typically, frost can occur when the temperature falls below 36°F, especially in rural areas. It is a localized phenomenon and can be quite variable across a small area. While the National Weather Service does not keep track of “frost” in observations per se, they do keep track of when temperatures hit the freezing mark or fall below. Frost becomes more widespread when the temperature falls below 32°F with some freeze possible. A hard freeze is possible when temperatures fall below 28°F. A hard freeze is a period of at least four consecutive hours of air temperatures that are below 25 degrees Fahrenheit (-4°C). Many plants can survive a brief frost, but very few can survive a hard freeze.
