USDA Zone 3B
Zone 3B Planting Calendar — May 18 to September 23
Zone 3b runs about 110 frost-free days between a late-May last frost and a mid-September first frost. Cool summers suit brassicas, roots and greens, while warm-season crops need indoor starts and short-season varieties. Soil warming lags air temperature by two to three weeks, so soil temperature is a better planting signal than the calendar.
Zone 3B at a glance: Last frost averages May 18 (range May 5 to June 1). First fall frost averages September 23. That is a frost-free span of about 126 days. Start warm-season crops indoors 6–10 weeks before last frost; transplant after May 18.

NOAA Frost Probability for Zone 3B
In Zone 3B, the last spring frost most likely lands on May 18. There's a 10% chance it could happen as late as June 1, and a 10% chance it's already done by May 5. These probabilities come from NOAA's 1991–2020 climate normals, weighted across every NOAA station serving the 196 ZIP codes in Zone 3B.

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 3B, 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 3B specifically, this composite was aggregated across 196 contributing ZIP codes (of 204 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 5) — 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 18) — the median. Half of historical years had their last frost on or before this date. This is the “Typical” reference.
- P90 (Jun 1) — 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 3B 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 3B
Data current as of Aug 12, 2026
In Zone 3B, the first fall frost most likely arrives on September 23, 2026. There's a 10% chance it comes as early as September 10, and a 10% chance it holds off until October 6. These probabilities come from NOAA's 1991–2020 climate normals, weighted across every NOAA station serving the 196 ZIP codes in Zone 3B.

Zone 3B Growing Tips
- Average last spring frost is May 18 and first fall frost is September 23 — these are the anchor dates your entire planting schedule is built around.
- Heat is brief. Cool summers suit cold-tolerant crops and make bolting less of a problem than further south.
- Rain concentrates June through August. Winters are dry, cold and reliably snow-covered.
- 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 30 and July 25 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 196 ZIP codes
in Zone 3B.
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.
