Tennessee Frost Dates: Last and First Frost by Town

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

Quick answer

Across Tennessee's 148 NOAA stations with regular frost, the median last spring frost is April 7 and the median first fall frost is October 29. Last frost dates range from March 16 at Memphis Intl Airport to May 22 at Mount Leconte, so enter your ZIP code below for the station nearest you.

How frost dates vary across Tennessee

Elevation matters: across Tennessee's stations, each 1,000 ft of elevation delays the median last frost by about 8 days.
Safety margin: the median 10%-risk date (April 25) 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 Tennessee?

The median last spring frost (32°F) across Tennessee's NOAA weather stations is April 7, based on 1991–2020 climate normals. It ranges from March 16 at Memphis Intl Airport to May 22 at Mount Leconte. For a safer planting date, use the 10%-risk date; the state median for that is April 25.

When is the first frost in Tennessee?

The median first fall frost across Tennessee's stations is October 29. The earliest median first frost is October 1 at Mount Leconte, and the latest is November 16 at Memphis Intl Airport.

How long is the growing season in Tennessee?

The median frost-free season is 204 days across Tennessee's stations, from 132 days at Mount Leconte to 244 days at Memphis Intl Airport.

When should I plant tomatoes in Tennessee?

Plant tomatoes outdoors after your local last frost, ideally after the 10%-risk date when nights stay above 50°F. At a typical Tennessee station that means starting seeds indoors 6–8 weeks before April 7 and transplanting from about April 25. 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.

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.
