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

All 4 stations agreeAt least one station

Every one of the 4 NOAA stations serving this county counts April 28 – October 17 as growing season (172 days). Widening to any single station gives April 12 – October 29 (200 days).

That is a 28-day difference inside one county — 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

Buckingham County covers 2 hardiness zones. A guide that gives the county one zone has picked whichever is largest and rounded everyone else into it — fine for the 50% in zone 7a and wrong for the other 50%. Here is the actual split.

Zone	ZIP codes	Share
7a	4	50%
7b	4	50%

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

Your freeze dates

Last spring freeze April 12 – April 28

First fall freeze October 17 – October 29

Across the 4 NOAA stations serving this county. These are medians — half of years freeze later than the date shown — so treat the later end of each range as the cautious one.

The growing season runs 172–199 days depending which station you are nearest, as published by NOAA rather than computed from the dates above. Summer highs average 84.5–89.8 °F in June–August. Summer rain over the same months runs 10.9–13.2" across those 4 stations, against the rough inch a week — about 13 inches over the same 92 days — that a vegetable garden is usually reckoned to want. The middle station covers about 96% 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 86 °F summer afternoon drying the soil faster than a cool one.

Every ZIP code in Buckingham County

Zones are published per ZIP code, not per county, so this is the exact answer rather than the county's average. The station column is the nearest one to that ZIP code's centroid and how far away it is — the same figure the tools use, shown here so you can see which ZIP codes are well covered and which are reaching.

ZIP code	USDA zone	Nearest NOAA station	Distance
23004	7a	Bremo Bluff, VA	10.0 km
23123	7a	Bremo Bluff, VA	6.5 km
23921	7b	Tye Rvr 1 SE, VA	27.9 km
23936	7b	Farmville 2 N, VA	23.4 km
24553	7b	Tye Rvr 1 SE, VA	14.9 km
24562	7a	Tye Rvr 1 SE, VA	28.8 km
24590	7a	Palmyra 3S, VA	18.6 km
24599	7b	Tye Rvr 1 SE, VA	18.5 km

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.

Offsets are published guidance; the dates they land on are computed from measured NOAA normals. The seed-starting tool does this for your own ZIP code and counts the days.

What survives the winter changes across Buckingham County

Zone 7a carries 58 of 74 perennial edibles; zone 7b carries 56. The best number is not always the warmest zone — the count peaks in the middle and falls both ways, because the warm end loses plants to insufficient winter chill and summer heat, not to cold.

Hardiness ranges are a judgement, published by growers rather than measured; the zone they are compared against is measured. On a warm-end verdict, check with your local extension service — a coastal zone 8 and an inland zone 8 are not the same summer.

Cautious — shortens the seasonMedian across stationsOptimistic

Last spring freeze: Plan to May 13 to be careful. Median April 12 – April 28 across 4 stations; March 29 is the optimistic end.
First fall freeze: Plan to October 5 to be careful. Median October 17 – October 29 across 4 stations; November 9 is the optimistic end.

NOAA publishes these as probabilities, not averages — 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.

The 4 stations behind these numbers

All 4 NOAA stations whose normals this page quotes, spanning about 54 km north to south. Every one is named with its identifier in the station list below — this page does not single one out, because no one station speaks for a whole county.

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.

These are the stations this county's ZIP codes actually cite as nearest — not a claim that each one sits inside its boundary, since a rural ZIP legitimately reaches over it. Every figure above comes from them, and each is named so you can check it.

Station	NOAA ID	Last spring freeze	First fall freeze	Season
Bremo Bluff, VA	USC00440993	April 28	October 17	172 days
Farmville 2 N, VA	USC00442941	April 12	October 29	199 days
Palmyra 3S, VA	USC00446491	April 23	October 21	180 days
Tye Rvr 1 SE, VA	USC00448600	April 15	October 25	193 days

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

Where these numbers come from

Hardiness zones are the USDA 2023 Plant Hardiness Zone Map, published per ZIP code by PRISM at Oregon State. Freeze dates and growing-season lengths are NOAA 1991–2020 Climate Normals, taken per station and cited above by name and NOAA ID.

County boundaries come from the Census ZCTA-to-county relation, which is what places each ZIP code — and which treats parishes, boroughs and census areas as county equivalents. No station is chosen to represent this county: every range above is taken across all of them and the count is stated, because picking one would be a judgement dressed as a measurement.
