Your ZIP code

Get the exact answer for your address

Everything above describes Charleston, WV 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 Charleston, WV is closing

Nothing in the 32-crop table still has time to mature here. The first fall freeze normally arrives October 16 – November 4 across the 12 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 February 10 – March 4 β€” counted back from a last spring freeze of April 7 – April 29 here.

These are ranges across the whole metro area. The ZIP lookup above gives the dates from your own nearest station instead.

Growing season across Charleston, WV A one-year bar. Every one of the 12 NOAA stations serving this metro area counts April 29 to October 16 as growing season, 170 days. At least one counts April 7 to November 4, 211 days. The same figures are written out below this chart. JFMAMJJASONDApril 29October 16

All 12 stations agreeAt least one station

Every one of the 12 NOAA stations serving this metro area counts April 29 – October 16 as growing season (170 days). Widening to any single station gives April 7 – November 4 (211 days).

That is a 41-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.

Which zone you are in depends where you are

Charleston, WV covers 2 hardiness zones. A guide that gives the metro one zone has picked whichever is largest and rounded everyone else into it β€” which is fine for the 89% in zone 7a and wrong for the other 11%. Here is the actual split.

Zone ZIP codes Share  
7a 74 89%
6b 9 11%

Zones are published per ZIP code, so yours is exact even though the metro's is not. The hardiness tool will tell you which one you are in.

Your freeze dates

Last spring freeze April 7 – April 29
First fall freeze October 16 – November 4

Those are the earliest and latest medians among the 12 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 12 stations serving Charleston, WV it runs 169–209 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 80–87 Β°F , below the 90 Β°F point where cool-season crops reliably bolt. Summer rain over the same months runs 13.8–16.7" across those 11 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. At the middle station that is covered, so watering in Charleston, WV is for the gaps between storms rather than the whole season. The inches are NOAA's published normals; the inch a week is a rule of thumb, and it takes no account of a 84 Β°F summer afternoon drying the soil faster than a cool one.

When to start seeds in Charleston, WV

Every spring job for 63 crop dates, counted from this metro's own last spring freeze. Each is a range across all 12 stations β€” the earliest and latest that job falls anywhere in the metro β€” because no one station speaks for the whole area.

What survives the winter changes across Charleston, WV

Of 74 perennial fruits, nuts, berries, vegetables and herbs, 58 come through the winter in zone 7a and only 51 in zone 6b. That is a different garden at each end of the same metro.

Zone ZIPs Survive Fail for being too warm
6b 9 51 of 74 0
7a 74 58 of 74 1

The last column is the counterintuitive one, and it is why the totals do not simply rise as the winters get milder. Most temperate fruit needs a documented number of hours below about 45 Β°F to break dormancy and set a crop, so an apple fails in a winter that is too warm; currants and rhubarb cook in the summer heat that comes with it. See the full list with reasons.

How certain the freeze dates are in Charleston, WV 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 May 17 to be careful. Median April 7 – April 29 across 12 stations; March 25 is the optimistic end.
First fall freeze
Plan to October 4 to be careful. Median October 16 – November 4 across 12 stations; November 16 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.

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.

Each of these takes a ZIP code and answers for that ZIP alone, citing the station it used and how far away it is. There is a ZIP box in the header of every page.

Other places to compare

These metros span exactly the same zones β€” 6b–7a β€” so the same plants are in and out of range across them. The freeze dates and the spring calendar are their own.

Gardening in West Virginia β€” zones 5b– 7a covers the whole state: how its 734 ZIP codes divide between 4 hardiness zones, and the freeze dates across every NOAA station 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.
