Everything above describes San Angelo, TX as a whole. Hardiness zones and freeze dates are published per ZIP code, so yours is exact β€” enter it and this page will tell you your zone, which NOAA station it comes from and how far away that station is.

Works for all 40,502 US ZIP codes. Freeze dates need a NOAA station within 100 km; where there is none, the page says so rather than estimating one.

The growing season in San Angelo, TX is closing

Nothing in the 32-crop table still has time to mature here. The first fall freeze normally arrives November 2 – November 14 across the 8 NOAA stations serving this metro area .

Your next season already has a date

The first job of it is πŸ§… Green Onions, start indoors, around January 23 – February 9 β€” counted back from a last spring freeze of March 20 – April 6 here.

Growing season across San Angelo, TX A one-year bar. Every one of the 8 NOAA stations serving this metro area counts April 6 to November 2 as growing season, 210 days. At least one counts March 20 to November 14, 239 days. The same figures are written out below this chart. JFMAMJJASONDApril 6November 2

All 8 stations agreeAt least one station

Every one of the 8 NOAA stations serving this metro area counts April 6 – November 2 as growing season (210 days). Widening to any single station gives March 20 – November 14 (239 days).

That is a 29-day difference inside one metro area β€” which is why this page gives ranges rather than a single planting date. The ZIP lookup above resolves it to one station.

Your freeze dates

Last spring freeze March 20 – April 6
First fall freeze November 2 – November 14

Those are the earliest and latest medians among the 8 stations serving this metro β€” not an average, and not one station standing in for the rest. Half of years freeze later than a station's own median.

The spread is the point. Even in a metro that is one hardiness zone throughout, its stations disagree about the last spring freeze. Hardiness zone and frost date measure different things β€” a zone is the average annual coldest night, a freeze date is when the season turns β€” and a place can be uniform in one and varied in the other. Use the tools below with your own ZIP rather than the ends of this range.

Your growing season

NOAA publishes a growing-season length for each station, and across the 8 stations serving San Angelo, TX it runs 211–238 days . That figure is published, not computed from the two freeze dates β€” subtracting one from the other gives the wrong answer wherever a season crosses New Year. Mean summer high (June–August) runs 93–96 Β°F , at or above the 90 Β°F point where cool-season crops bolt and tomato and pepper pollen fails β€” so midsummer sowings of lettuce and its relatives are worth holding here. Summer rain over the same months runs 5.8–7.9" across those 8 stations, against the rough inch a week β€” about 13 inches over the same 92 days β€” that a vegetable garden is usually reckoned to want. The middle station covers about 52% of it, so expect to make up the rest. The inches are NOAA's published normals; the inch a week is a rule of thumb, and it takes no account of a 95 Β°F summer afternoon drying the soil faster than a cool one.

When to start seeds in San Angelo, TX

Every spring job for 63 crop dates, counted from this metro's own last spring freeze. Each is a range across all 8 stations β€” the earliest and latest that job falls anywhere in the metro β€” because no one station speaks for the whole area.

What lives through a zone 8a winter

Winter hardiness runs on the zone alone, so this one is exact for the whole of San Angelo, TX rather than a range. Of 74 perennial fruits, nuts, berries, vegetables and herbs, 57 come through a zone 8a winter β€” and 8 of the failures are not about cold at all, but about winters too mild to break dormancy or summers too hot.

Among them: Apple, Aronia, Elderberry, Summer Raspberry, Asparagus, Horseradish, Rhubarb, Sunchoke. See the full list with reasons.

How certain the freeze dates are in San Angelo, TX Two rows. Each runs from the cautious date, which shortens the growing season, to the optimistic one. The median dates sit between them. Every figure is repeated in the text below this chart. JFMAMJJASONDLast spring freezeFirst fall freeze

Cautious β€” shortens the seasonMedian across stationsOptimistic

Last spring freeze
Plan to April 24 to be careful. Median March 20 – April 6 across 8 stations; February 28 is the optimistic end.
First fall freeze
Plan to October 18 to be careful. Median November 2 – November 14 across 8 stations; December 2 is the optimistic end.

NOAA publishes these as probabilities, not averages β€” the middle figure is a median, so half of years fall either side of it. The cautious end is the 10% tail: in roughly nine years in ten the freeze falls on the safe side of it.

All 8 NOAA stations whose normals this page quotes, spanning about 60 km north to south. Every one is named with its identifier in the station list below β€” this page does not single one out, because no one station speaks for a whole metro area.

A relative sketch, not a map with a projection: longitude is adjusted for latitude so the shape is not stretched, and there is no basemap. For the one station nearest a specific address, with its real distance, use the ZIP lookup above.

Every figure above comes from these, and each is named so you can check it. Which station serves a given ZIP code, and how far away it is, varies across the metro β€” the table below gives it per ZIP code rather than this page averaging it.

These are medians, not averages β€” NOAA publishes freeze dates as a probability distribution, and half of years freeze later than the date shown.

ZIP-code positions are area centroids, so a large rural ZIP code's listed distance is measured from the middle of its area rather than from any particular address in it.

Where these numbers come from

The hardiness zone is the USDA 2023 Plant Hardiness Zone Map, published per ZIP code by PRISM at Oregon State. The freeze dates are NOAA's 1991–2020 Climate Normals, read from every station whose normals cover a ZIP code in this metro. Nothing here is estimated, and no station stands in for another.

This page names no single station on purpose. Picking one to represent a metro sounds reasonable and is not: the station serving the most ZIP codes is an artifact of where ZIP centroids happen to fall, and it selects a lock on the Monongahela for Pittsburgh and a far southern suburb for Chicago. A range across every station is true; a single cited date for a whole metro is not.
