Everything above describes Hancock County, Ohio as a whole. Hardiness zones and freeze dates are published per ZIP code, so yours is exact — enter it and this page will tell you your zone, which NOAA station it comes from and how far away that station is.
The growing season in Hancock County is closing
Nothing in the 32-crop table still has time to mature here. The first fall freeze normally arrives October 21 – October 24 across the 4 NOAA stations serving this county .
Your next season already has a date
The first job of it is 🧅 Green Onions, start indoors, around February 22 – February 27 — counted back from a last spring freeze of April 19 – April 24 here.
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 24 – October 21 as growing season (180 days). Widening to any single station gives April 19 – October 24 (188 days).
Which zone you are in depends where you are
Hancock 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 75% in zone 6a and wrong for the other 25%. Here is the actual split.
| Zone | ZIP codes | Share | |
|---|---|---|---|
| 6a | 9 | 75% | |
| 6b | 3 | 25% |
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
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 179–185 days depending which station you are nearest, as published by NOAA rather than computed from the dates above. Summer highs average 82.3–83.7 °F in June–August. Summer rain over the same months runs 10.9–11.8" 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 90% 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 83 °F summer afternoon drying the soil faster than a cool one.
Every ZIP code in Hancock 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 |
|---|---|---|---|
| 44804 | 6b | Findlay Wpcc, OH | 12.6 km |
| 45814 | 6a | Findlay AP, OH | 13.8 km |
| 45816 | 6a | Findlay AP, OH | 10.6 km |
| 45840 | 6b | Findlay AP, OH | 2.1 km |
| 45841 | 6a | Findlay AP, OH | 15.7 km |
| 45858 | 6a | Hoytville 2 NE, OH | 12.5 km |
| 45867 | 6a | Findlay AP, OH | 17.1 km |
| 45868 | 6a | Pandora, OH | 9.7 km |
| 45881 | 6a | Findlay AP, OH | 12.0 km |
| 45889 | 6a | Findlay Wpcc, OH | 12.0 km |
| 45890 | 6b | Findlay AP, OH | 15.1 km |
| 45897 | 6a | Findlay AP, OH | 19.2 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.

What survives the winter changes across Hancock County
Zone 6a carries 51 of 74 perennial edibles; zone 6a carries 51.
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 10 to be careful. Median April 19 – April 24 across 4 stations; April 5 is the optimistic end.
- First fall freeze
- Plan to October 4 to be careful. Median October 21 – October 24 across 4 stations; November 5 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 30 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 |
|---|---|---|---|---|
| Findlay AP, OH | USW00014825 | April 19 | October 23 | 185 days |
| Findlay Wpcc, OH | USC00332791 | April 22 | October 24 | 183 days |
| Hoytville 2 NE, OH | USC00333874 | April 24 | October 21 | 179 days |
| Pandora, OH | USC00336405 | April 23 | October 22 | 180 days |
These are medians, not averages — NOAA publishes freeze dates as a probability distribution, and half of years freeze later than the date shown.

If you want to act on this
Each link opens an Amazon search rather than a product we picked. We have not tested these and do not rank them — the search is the honest version, and you choose.
- Trunk wrapZone 6a is cold enough that winter sun on a young trunk does more damage than the cold does.
- Row cover and frost clothThe season here closes at the first fall freeze dated above — a cover buys back some of those days at the end.
- MulchFor the perennials nearest their cold limit in zone 6a, where an insulated crown is what decides whether they come back.
As an Amazon Associate we earn from qualifying purchases. That costs you nothing extra, and it buys no influence over anything on this site: the dates come from NOAA normals and the zones from the USDA, and no product affects either.

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.
