Frost Dates and Planting Windows in Alabama

The 32°F frost dates at the 118 weather stations in Alabama with NOAA's 1991–2020 Climate Normals, and the planting windows they give. These are long-term statistics, not a forecast. For the dates at the station nearest you, enter your ZIP code.

Frost dates across Alabama

Each risk level uses a date with a set chance of frost. In spring, it's the chance of a 32°F frost on or after the last-frost date. In fall, it's the chance of the first 32°F frost on or before the first-frost date. At the Typical level (30%), the last frost ranges from February 8 to April 18 across the state, and the first frost from October 22 to December 29.

At 7 of these 118 stations, 32°F isn't reached every year. Their frost dates describe only the years when it is reached, and the ranges on this page include them.

Growing season length

The growing season is the stretch between the last spring frost and the first fall frost at 32°F. NOAA gives it as a length with a chance of being at least that long. Each risk level uses the length with that chance of a shorter season, so Conservative shows the shortest lengths.
