Planting zones in Curry County, Oregon

This county spans USDA zones 9a to 9b, so there is no single zone for Curry County and anyone who gives you one is rounding. 67% of its ZIP codes are zone 9b; the rest are not.

USDA zones 9a–9b 2 zones across 6 ZIP codes
ZIP codes 6 6 have a NOAA station within range
Weather stations 5 NOAA 1991–2020 normals, across 1,628 sq mi

Your ZIP code

Get the exact answer for your address

Everything above describes Curry County, Oregon 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.

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.

What you can sow in Curry County now

12 of 32 crops that every one of the 5 NOAA stations serving this county agrees still has time to mature — with a week in hand, so this holds until the page is next rebuilt.

Counted against a first fall freeze of November 17 – December 27 across 5 of those stations, NOAA 1991–2020 normals.

A further 14 crops depend on where in Curry County you are — its stations disagree about them. The ZIP lookup above settles it for one address.

Growing season across Curry County A one-year bar. Every one of the 5 NOAA stations serving this county counts March 30 to November 17 as growing season, 232 days. At least one counts January 31 to December 27, 330 days. The same figures are written out below this chart. JFMAMJJASONDMarch 30November 17

All 5 stations agreeAt least one station

Every one of the 5 NOAA stations serving this county counts March 30 – November 17 as growing season (232 days). Widening to any single station gives January 31 – December 27 (330 days).

That is a 98-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

Curry 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 67% in zone 9b and wrong for the other 33%. Here is the actual split.

Zone ZIP codes Share  
9b 4 67%
9a 2 33%

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 January 31 – March 30
First fall freeze November 17 – December 27

Across the 5 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 233–334 days depending which station you are nearest, as published by NOAA rather than computed from the dates above. Summer highs average 66.5–87.3 °F in June–August. Summer rain over the same months runs 2.5–2.9" 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 22% of it, so a summer garden here is watered rather than rained on. The inches are NOAA's published normals; the inch a week is a rule of thumb, and it takes no account of a 68 °F summer afternoon drying the soil faster than a cool one.

Every ZIP code in Curry 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
97406 9a Illahe, OR 3.3 km
97415 9b Brookings 2 SE, OR 15.1 km
97444 9b Gold Beach RS, OR 8.9 km
97450 9a Langlois #2, OR 6.6 km
97465 9b Port Orford #2, OR 12.8 km
97476 9b Langlois #2, OR 10.0 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 Curry County

Zone 9a carries 46 of 74 perennial edibles; zone 9b carries 40. 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.

At least one station here freezes across the new year, which puts the two ends of a spread on opposite sides of the calendar. Drawing it would produce a bar spanning almost the whole year and meaning nothing, so none is drawn.

The 5 stations behind these numbers

The 5 NOAA stations serving Curry County A relative sketch of where the stations sit, about 99 kilometres north to south. Each is named with its NOAA identifier in the station list on this page, which carries the same information as text.

All 5 NOAA stations whose normals this page quotes, spanning about 99 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.

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.

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.

Sources

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.
