Mississippi Frost Dates: Last and First Frost by Town

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

Quick answer

Across Mississippi's 94 NOAA stations with regular frost, the median last spring frost is March 17 and the median first fall frost is November 12. Last frost dates range from February 12 at Biloxi to April 9 at Iuka, so enter your ZIP code below for the station nearest you.

How frost dates vary across Mississippi

North vs south: stations in the northern third of the state (north of 33.7°N) reach their median last frost about 17 days later than the southern third (south of 32.0°N).
Safety margin: the median 10%-risk date (April 6) is about 20 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 Mississippi?

The median last spring frost (32°F) across Mississippi's NOAA weather stations is March 17, based on 1991–2020 climate normals. It ranges from February 12 at Biloxi to April 9 at Iuka. For a safer planting date, use the 10%-risk date; the state median for that is April 6.

When is the first frost in Mississippi?

The median first fall frost across Mississippi's stations is November 12. The earliest median first frost is October 26 at Holly Springs 4 N, and the latest is December 14 at Gulfport Naval Center.

How long is the growing season in Mississippi?

The median frost-free season is 239 days across Mississippi's stations, from 202 days at Hickory Flat to 301 days at Biloxi.

When should I plant tomatoes in Mississippi?

Plant tomatoes outdoors after your local last frost, ideally after the 10%-risk date when nights stay above 50°F. At a typical Mississippi station that means starting seeds indoors 6–8 weeks before March 17 and transplanting from about April 6. 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.
