USDA Zone 9A

Zone 9A Planting Calendar — March 4 to November 26

Zone 9a covers the hot desert Southwest (Phoenix, Las Vegas) and mild coastal California — two very different growing environments in the same zone. Desert gardeners follow a mostly inverted calendar, growing October through May and resting during summer highs that regularly exceed 105°F. California 9a supports near year-round growing with strategic heat management.

Zone 9A at a glance: Last frost averages March 4 (range February 5 to March 27). First fall frost averages November 26. That is a frost-free span of about 267 days. Start warm-season crops indoors 6–10 weeks before last frost; transplant after March 4.

NOAA Frost Probability for Zone 9A

Computed across 1,767 ZIP codes in Zone 9A · Composite generated Aug 12, 2026 | NOAA NCEI 1991-2020 Climate Normals (released 2021) | Threshold: minimum temperature at or below 32°F (NCEI element TMIN-PRBLST-T32F) — some crops are damaged above 32°F too, depending on duration, humidity, wind, and crop sensitivity
In Zone 9A, the last spring frost most likely lands on March 4. There's a 10% chance it could happen as late as March 27, and a 10% chance it's already done by February 5. These probabilities come from NOAA's 1991–2020 climate normals, weighted across every NOAA station serving the 1,767 ZIP codes in Zone 9A.

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 9A, 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 9A specifically, this composite was aggregated across 1,767 contributing ZIP codes (of 2,199 total ZIP codes assigned to this zone in the USDA 2023 Plant Hardiness Zone Map).

Data sources

NOAA NCEI 1991–2020 U.S. Annual/Seasonal Climate Normals — the authoritative U.S. climatological dataset, released by NOAA in 2021 and covering frost-date probabilities at six temperature thresholds and nine probability percentiles for thousands of stations nationwide. Dataset identifier: gov.noaa.ncdc:C01619.

Methodology paper: Palecki, M., Durre, I., Applequist, S., Arguez, A., Lawrimore, J. (2021). U.S. Climate Normals 2020: U.S. Annual/Seasonal Climate Normals (1991–2020). NOAA National Centers for Environmental Information.

Station ↔ ZIP crosswalk: built from NOAA’s GHCN station inventory and the U.S. Census Bureau 2024 ZCTA Gazetteer (public domain) using great-circle distance with inverse-distance-squared weighting.

Live freeze outlook: National Weather Service (NWS) public forecast API, for the location of a ZIP you enter. Used only within about 7 days of a forecast freeze, the range an NWS point forecast reaches; without a ZIP, or outside that window, the chart shows the NOAA climate normal alone.

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 (Feb 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 (Mar 4) — the median. Half of historical years had their last frost on or before this date. This is the “Typical” reference.
  • P90 (Mar 27) — 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 9A 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 9A

Data current as of Aug 12, 2026
In Zone 9A, the first fall frost most likely arrives on November 26, 2026. There's a 10% chance it comes as early as November 6, and a 10% chance it holds off until December 20. These probabilities come from NOAA's 1991–2020 climate normals, weighted across every NOAA station serving the 1,767 ZIP codes in Zone 9A.

Zone 9A Growing Tips

States in Zone 9A

Zone 9A spans parts of these states. Note that zone boundaries run within states — check your specific ZIP code for your exact zone.

Texas (south central) Florida (central) California (Los Angeles basin, Sacramento valley) Arizona (Phoenix metro) New Mexico (south)

What works well in Zone 9A

Zone 9a (Phoenix-style hot desert) runs on an inverted calendar: production from October through May, summer dormancy June through September. With 8 inches of annual rainfall and 106°F July highs, gardens are water-limited and heat-limited more than frost-limited. (Coastal California 9a is much milder and less of a summer-shutdown desert calendar.)

Drip irrigation / soaker hose kit

Critical

Every gardener benefits from putting water at the root zone instead of on the leaves, because drip and soaker systems reduce foliar disease pressure by limiting leaf wetness and soil splash. A quality kit should include a backflow preventer, filter, pressure reducer, and UV-resistant tubing.

Garden shade cloth

Critical

K-State Research and Extension and University of Maryland Extension recommend shade cloth as a heat-management tool for vegetable gardens, with 30 percent shade rating most effective for tomatoes, peppers, and fruiting crops, and 40 to 50 percent for protecting heat-sensitive greens during hot summer months. University of Delaware research found 30 percent black shade cloth tripled marketable yield for bell peppers compared to unshaded plants, and Purdue trials showed shade cloth reduced maximum daily temperatures by 8 to 10 degrees Fahrenheit. Choose knitted polyethylene with reinforced grommets every 18 to 24 inches, mount on hoops or a frame with open sides for airflow, and remove or vent during prolonged wet weather to avoid increased humidity in the canopy.

Mulch / landscape fabric

High

Nearly every garden benefits from mulch for weed suppression, moisture conservation, and soil temperature moderation. For most home gardeners, quality organic mulch is the better buy over landscape fabric.

Source: Penn State Extension; Wisconsin Horticulture; Illinois Extension

Budget Seeding Straw Mulch (1 cu ft, covers ~250 sq ft) Processed wheat straw with biodegradable tackifier for slope retention. The most-reviewed garden straw on Amazon (1.8K+ reviews).

Best value Cleaned Wheat Straw Mulch (3 cu ft, ~20 lbs) Thoroughly cleaned wheat straw at 3 cubic feet, marketed specifically for vegetable gardens rather than animal bedding or decoration.

Soil moisture meter (root-zone probe)

High

University of Arizona Cooperative Extension notes that most vegetables root in the top 12 to 24 inches of soil and that hot, dry periods require more frequent irrigation, but watering by habit often wets only the top inch while leaving the root zone dry. A dedicated soil moisture meter with a long probe gives gardeners a deterministic reading at root depth instead of guessing from surface appearance, which is most critical in low-rainfall desert zones (Zone 9a Phoenix) and in raised beds or containers that dry from the top down. Look for a single-purpose moisture meter (not a 3-in-1 or 4-in-1 combo, which trade accuracy for feature count) with a probe that reaches 8 to 12 inches and a clear analog or digital display.

Budget Soil Moisture Meter (stainless steel probe) The original XLUX moisture meter with a 304 stainless steel probe — won't corrode in alkaline desert soils or humid Gulf Coast beds.

Reflective plastic mulch (white-on-black or silver)

Medium

North Carolina State Extension reports that white-on-black plastic mulch can reduce soil temperature by 5 to 20 degrees Fahrenheit and silver mulch by about 6 degrees, the opposite effect of black mulch which warms soil. This makes reflective mulch the appropriate plasticulture choice for hot zones (especially Zone 9a desert and other high-heat low-humidity areas) where overheating limits warm-season crop performance more than cold soil. Silver mulch adds documented aphid and thrips repellency from the reflective surface. Use only with drip irrigation installed underneath, never use plastic mulch without irrigation, and reserve for late spring or early fall plantings where the surrounding heat is the primary stress.

Frost dates from NOAA NCEI 1991-2020 U.S. Climate Normals (dataset gov.noaa.ncdc:C01619; methodology Palecki et al. 2021), aggregated across 1,767 ZIP codes in Zone 9A. 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.
