Final Frost Date & Gardening Tips

"Clear moon, frost soon" is the old farmer's adage for predicting frost. This indicates that if the atmosphere is clear, there is no blanket of clouds to trap the heat radiating from the earth's surface. If the night temperature is low enough, and there is no wind, frost may form on such a clear night. Nowadays, we can rely on a more advanced system for predicting frost. Each year a range of local data is collected to predict the first and last frost dates for a region. The last frost date in the spring and the first frost date in the fall dictate how long the growing season will be, allowing us to plan our gardens accordingly.
