Louisiana Frost Dates: Last and First Frost by Town

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

Quick answer

Across Louisiana's 98 NOAA stations with regular frost, the median last spring frost is March 1 and the median first fall frost is November 24. Last frost dates range from January 22 at New Orleans Lakefront Airport to March 30 at Homer 1N, so enter your ZIP code below for the station nearest you.

How frost dates vary across Louisiana

North vs south: stations in the northern third of the state (north of 31.6°N) reach their median last frost about 29 days later than the southern third (south of 30.2°N).
Safety margin: the median 10%-risk date (March 22) is about 21 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 Louisiana?

The median last spring frost (32°F) across Louisiana's NOAA weather stations is March 1, based on 1991–2020 climate normals. It ranges from January 22 at New Orleans Lakefront Airport to March 30 at Homer 1N. For a safer planting date, use the 10%-risk date; the state median for that is March 22.

When is the first frost in Louisiana?

The median first fall frost across Louisiana's stations is November 24. The earliest median first frost is November 5 at Calhoun Rsch Station, and the latest is January 9 at Boothville Asos.

How long is the growing season in Louisiana?

The median frost-free season is 268 days across Louisiana's stations, from 221 days at Homer 1N to 357 days at Boothville Asos.

When should I plant tomatoes in Louisiana?

Plant tomatoes outdoors after your local last frost, ideally after the 10%-risk date when nights stay above 50°F. At a typical Louisiana station that means starting seeds indoors 6–8 weeks before March 1 and transplanting from about March 22. 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.
