The last spring frost marks the approximate beginning of the growing season for frost-sensitive crops and plants. The date of the last spring frost is the first occurrence of at least one consecutive day with minimum temperature greater than 0°C (Tmin > 0) before July 15.

The first fall frost marks the approximate end of the growing season for frost-sensitive crops and plants. The date of the first fall frost is the first occurrence of at least one consecutive day with minimum temperature less than 0°C (Tmin < 0) after July 15.

The Frost-Free Season is the approximate length of the growing season, during which there are no freezing temperatures to kill or damage plants. This is the number of days between the Last Spring Frost and the First Fall Frost.
