Missouri Frost Dates: Last and First Frost by Town

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

Quick answer

Across Missouri's 171 NOAA stations with regular frost, the median last spring frost is April 12 and the median first fall frost is October 24. Last frost dates range from March 24 at Caruthersville to April 27 at Rosebud, so enter your ZIP code below for the station nearest you.

How frost dates vary across Missouri

  • North vs south: stations in the northern third of the state (north of 39.0°N) reach their median last frost about 6 days later than the southern third (south of 37.6°N).
  • Safety margin: the median 10%-risk date (April 29) is about 17 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.

Last frost and first frost are medians: a 50% chance of a 32°F night after (spring) or before (fall) that date. 10% risk is the spring date with only a 1-in-10 chance of a later frost. Click a column to sort.

Frequently asked questions

When is the last frost in Missouri?

The median last spring frost (32°F) across Missouri's NOAA weather stations is April 12, based on 1991–2020 climate normals. It ranges from March 24 at Caruthersville to April 27 at Rosebud. For a safer planting date, use the 10%-risk date; the state median for that is April 29.

When is the first frost in Missouri?

The median first fall frost across Missouri's stations is October 24. The earliest median first frost is October 8 at Steelville 2 N, and the latest is November 9 at Caruthersville.

How long is the growing season in Missouri?

The median frost-free season is 194 days across Missouri's stations, from 164 days at Steelville 2 N to 230 days at Caruthersville.

When should I plant tomatoes in Missouri?

Plant tomatoes outdoors after your local last frost, ideally after the 10%-risk date when nights stay above 50°F. At a typical Missouri station that means starting seeds indoors 6–8 weeks before April 12 and transplanting from about April 29. 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.
