Nebraska Frost Dates: Last and First Frost by Town

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

Quick answer

Across Nebraska's 184 NOAA stations with regular frost, the median last spring frost is May 2 and the median first fall frost is October 7. Last frost dates range from April 15 at Valley NWS to May 30 at Agate 3 E, so enter your ZIP code below for the station nearest you.

How frost dates vary across Nebraska

Elevation matters: across Nebraska's stations, each 1,000 ft of elevation delays the median last frost by about 6 days.
North vs south: stations in the northern third of the state (north of 41.8°N) reach their median last frost about 10 days later than the southern third (south of 41.0°N).
Safety margin: the median 10%-risk date (May 15) is about 13 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 Nebraska?

The median last spring frost (32°F) across Nebraska's NOAA weather stations is May 2, based on 1991–2020 climate normals. It ranges from April 15 at Valley NWS to May 30 at Agate 3 E. For a safer planting date, use the 10%-risk date; the state median for that is May 15.

When is the first frost in Nebraska?

The median first fall frost across Nebraska's stations is October 7. The earliest median first frost is September 11 at Agate 3 E, and the latest is October 21 at Valley NWS.

How long is the growing season in Nebraska?

The median frost-free season is 157 days across Nebraska's stations, from 103 days at Agate 3 E to 187 days at Valley NWS.

When should I plant tomatoes in Nebraska?

Plant tomatoes outdoors after your local last frost, ideally after the 10%-risk date when nights stay above 50°F. At a typical Nebraska station that means starting seeds indoors 6–8 weeks before May 2 and transplanting from about May 15. 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.
