New Mexico Frost Dates: Last and First Frost by Town

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

Quick answer

Across New Mexico's 175 NOAA stations with regular frost, the median last spring frost is April 29 and the median first fall frost is October 17. Last frost dates range from March 9 at Alamogordo to June 19 at Wolf Canyon, so enter your ZIP code below for the station nearest you.

How frost dates vary across New Mexico

Elevation matters: across New Mexico's stations, each 1,000 ft of elevation delays the median last frost by about 14 days.
North vs south: stations in the northern third of the state (north of 35.6°N) reach their median last frost about 29 days later than the southern third (south of 33.9°N).
Safety margin: the median 10%-risk date (May 13) is about 14 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.

All 175 stations in New Mexico

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 New Mexico?

The median last spring frost (32°F) across New Mexico's NOAA weather stations is April 29, based on 1991–2020 climate normals. It ranges from March 9 at Alamogordo to June 19 at Wolf Canyon. For a safer planting date, use the 10%-risk date; the state median for that is May 13.

When is the first frost in New Mexico?

The median first fall frost across New Mexico's stations is October 17. The earliest median first frost is September 7 at Red River, and the latest is November 18 at Alamogordo.

How long is the growing season in New Mexico?

The median frost-free season is 167 days across New Mexico's stations, from 77 days at Red River to 251 days at Alamogordo.

When should I plant tomatoes in New Mexico?

Plant tomatoes outdoors after your local last frost, ideally after the 10%-risk date when nights stay above 50°F. At a typical New Mexico station that means starting seeds indoors 6–8 weeks before April 29 and transplanting from about May 13. 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.
