USDA Zone 3A
Zone 3A Planting Calendar — May 22 to September 21
Zone 3a has the shortest growing season in the lower 48 — roughly 95 frost-free days, with winter minimums reaching -40°F. Frost is possible in almost any month in low-lying ground, so raised beds, black plastic and the shortest-maturing varieties available are what make a harvest possible at all. Reliable snow cover is what protects perennial roots through winter.
Zone 3A at a glance: Last frost averages May 22 (range May 8 to June 7). First fall frost averages September 21. That is a frost-free span of about 102 days. Start warm-season crops indoors 6–10 weeks before last frost; transplant after May 22.

NOAA Frost Probability for Zone 3A
In Zone 3A, the last spring frost most likely lands on May 22. There's a 10% chance it could happen as late as June 7, and a 10% chance it's already done by May 8. These probabilities come from NOAA's 1991–2020 climate normals, weighted across every NOAA station serving the 5 ZIP codes in Zone 3A.

How we calculate this
NOAA provides station-level Climate Normals. NOAA's National Centers for Environmental Information (NCEI) records daily minimum temperatures at thousands of U.S. weather stations and publishes, for each station, the probability that the last spring frost has occurred by each calendar date — based on 30 years of observations (1991–2020). These per-station probability percentiles are the primary data.
SoilStack aggregates those station-level normals into a per-USDA-zone composite. For each ZIP code in Zone 3A, we identify nearby NOAA stations, weight each station's contribution by inverse-distance squared to the ZIP centroid, build a per-ZIP composite from those weighted station percentiles, and then aggregate every per-ZIP composite in the zone into a single zone-level composite using a weighted circular mean for dates and a weighted arithmetic mean for numeric values like growing-season length.
For Zone 3A specifically, this composite was aggregated across 5 contributing ZIP codes (of 5 total ZIP codes assigned to this zone in the USDA 2023 Plant Hardiness Zone Map).

How to read this chart
The curve shows the cumulative probability that the last spring frost has occurred by each date. It rises from 0% (no chance frost is done that early) to 100% (essentially certain frost has occurred by that late date).
Three reference points are highlighted:
- P10 (May 8) — the earliest date by which there’s a 10% chance the last frost is already done. Gardeners willing to take risk on early planting anchor decisions here.
- P50 (May 22) — the median. Half of historical years had their last frost on or before this date. This is the “Typical” reference.
- P90 (Jun 7) — the date by which there’s a 90% chance frost is done. Risk-averse gardeners planting frost-sensitive crops use this date as their go-ahead signal.
For most warm-season crops (tomatoes, peppers, basil, beans), waiting until the P50 to P90 window is the conservative call. Hardier crops can go in around P10.
The typical last-frost line. The P50 marker is the climate-normal center — the median last-frost date from 30 years of NOAA data. If you enter your ZIP and a freeze is within the 7-day National Weather Service window, a separate marker shows that forecast freeze for your location. A forecast freeze is not necessarily the season’s last: later freezes remain possible.
Limitations
Climate normals plus a short-range forecast blend. The probability curve reflects the climatological baseline from 1991–2020: what’s likely in a typical year. The optional freeze outlook adds the live NWS forecast for your ZIP when a freeze is within about 7 days, the range where a genuine point forecast exists. Without a ZIP, or beyond that horizon, the chart stays on the climate normal, because no forecast can reliably see further out. An early warm spell does not move the estimate earlier on its own, since last frost dates do not reliably track spring warmth.
Microclimate variation. A zone composite represents the weighted average across hundreds of stations. Your specific ZIP may run several days warmer or cooler than the zone average due to elevation, water proximity, urban heat island, or local topography.
Station density. Zone 3A has dense NOAA station coverage. Some zones with sparser ZIP-level coverage (Alaska, parts of the desert Southwest) rely on fewer mapped ZIPs and should be interpreted with slightly more caution.
Data refresh cycle. NOAA releases new Climate Normals on a 10-year cycle. The current 1991–2020 dataset will be superseded by the 2001–2030 release expected in 2031.

First Fall Frost for Zone 3A
Data current as of Aug 12, 2026
In Zone 3A, the first fall frost most likely arrives on September 21, 2026. There's a 10% chance it comes as early as September 6, and a 10% chance it holds off until October 5. These probabilities come from NOAA's 1991–2020 climate normals, weighted across every NOAA station serving the 5 ZIP codes in Zone 3A.

Planning ahead
The typical first fall frost is around September 21 in Zone 3A, somewhere between September 6 and October 5. That is the climate-normal center from 30 years of NOAA data. Enter your ZIP above for a forecast tied to your location when a freeze is within the 7-day window.

Zone 3A Growing Tips
- Average last spring frost is May 22 and first fall frost is September 21 — these are the anchor dates your entire planting schedule is built around.
- Heat stress is rare. Cool nights all summer favour brassicas, roots and greens.
- Most rain falls June through August. Winter is dry and snow-covered, and that snow cover is what protects perennial roots.
- Disease pressure in this zone is low. Primary risks include early blight, downy mildew. Proper plant spacing, air circulation, and avoiding overhead watering significantly reduce disease incidence.
- Fall cool-season crops (lettuce, spinach, kale, radishes) should go in the ground between June 25 and July 20 for harvest before hard frost arrives.

Frost dates from NOAA NCEI 1991-2020 U.S. Climate Normals
(dataset gov.noaa.ncdc:C01619; methodology Palecki et al. 2021),
aggregated across 5 ZIP codes
in Zone 3A.
First fall frost is aggregated the same way as spring, from NOAA element ANN-TMIN-PRBFST-T32F. Growing season is NOAA's own published normal (ANN-TMIN-PRBGSL-T32F), measured per year and then averaged — not the gap between the two dates above, which is a slightly different quantity.
Planting dates are averages based on zone frost dates and standard horticultural timing — adjust for your local microclimate.
