Alabama Frost Dates: Last and First Frost by Town

118 NOAA weather stations · 1991–2020 U.S. Climate Normals · Data updated 2026-10-29

Quick answer

Across Alabama's 118 NOAA stations with regular frost, the median last spring frost is March 22 and the median first fall frost is November 9. Last frost dates range from January 31 at Dauphin Island #2 to April 11 at Hamilton 3 S, so enter your ZIP code below for the station nearest you.

How frost dates vary across Alabama

North vs south: stations in the northern third of the state (north of 33.7°N) reach their median last frost about 19 days later than the southern third (south of 32.0°N).
Safety margin: the median 10%-risk date (April 9) is about 18 days after the median last frost. Waiting until then cuts the chance of a killing frost on tender transplants from 1 in 2 to 1 in 10.

Frequently asked questions

When is the last frost in Alabama?

The median last spring frost (32°F) across Alabama's NOAA weather stations is March 22, based on 1991–2020 climate normals. It ranges from January 31 at Dauphin Island #2 to April 11 at Hamilton 3 S. For a safer planting date, use the 10%-risk date; the state median for that is April 9.

When is the first frost in Alabama?

The median first fall frost across Alabama's stations is November 9. The earliest median first frost is October 27 at Camp Hill 2NW, and the latest is January 6 at Dauphin Island #2.

How long is the growing season in Alabama?

The median frost-free season is 233 days across Alabama's stations, from 198 days at Hamilton 3 S to 340 days at Dauphin Island #2.

When should I plant tomatoes in Alabama?

Plant tomatoes outdoors after your local last frost, ideally after the 10%-risk date when nights stay above 50°F. At a typical Alabama station that means starting seeds indoors 6–8 weeks before March 22 and transplanting from about April 9. Check your ZIP code, because dates vary by weeks across the state.

How to use these dates

Frost dates are 30-year averages from NOAA, not forecasts. Use them to plan seed starting and planting, then watch the 10-day forecast as the date approaches. Cold air settles in valleys and low spots, so a garden at the bottom of a slope can frost a week or more later in spring than the nearest station shows.

Ready to plan? The planting calendar by ZIP code turns these dates into start-indoors, transplant and sowing dates for 30 crops.

Sources and method

Dates are the 32°F freeze probabilities published in the NOAA NCEI 1991–2020 U.S. Climate Normals for each station. Station names are NOAA's, lightly expanded for readability. See the methodology or download the full table.
