Cokeville, Wyoming, sits in USDA hardiness zone 4a — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Reliable performers under these conditions include okra, cranberry, cilantro, and zucchini; what your own ground favors still comes down to its soil, sun, and drainage.
Even in Cokeville, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Cokeville lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Cokeville
Each reading below is measured for Cokeville itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredCokeville runs about 118 days between hard freezes — a short growing season.
Long-maturing crops like melons, sweet potatoes, and winter squash can run out of runway before the first hard freeze, ripening late or not at all.
Lead with fast-maturing varieties, and stretch the season on both ends with cold frames, low tunnels, or a greenhouse.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredCokeville sits in USDA hardiness zone 4a.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country Cokeville is in
Cokeville sits in the Wyoming Basin — EPA Level III, inside the wider North American Deserts. That is read at Cokeville's own centroid rather than borrowed from Lincoln County.

Is it too late to plant in Cokeville?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Apr 21; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 19 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 14 — long-season crops need about 90 days of runway, quick greens only 30. In a season this compact, fast finishers and cold-hardy greens do the late work, and garlic tucked in before the freeze repays you next summer.

Know Before You Grow
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.
- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •A Superfund listing means federally documented contamination. Test soil and water before planting edibles nearby.

Your land is one point inside Cokeville
Everything above resolves to Cokeville as a whole — one PHZM band and one 28°F frost record, read across 817 acres. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about Cokeville
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Cokeville’s own record; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Cokeville
When does frost risk typically end in Cokeville?
The last hard freeze (28°F) in Cokeville typically lands around May 19, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Jun 9.
When is the first frost in Cokeville?
The first hard freeze (28°F) in Cokeville typically arrives around Sep 14, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Aug 31, so the watching starts about Aug 15 — about 118 days after the spring freeze cleared.
How long is the growing season in Cokeville?
Measured between 28°F hard freezes, Cokeville sees about 118 frost-free days — roughly May 19 through Sep 14, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 9 to Aug 31, about 83 days.
Is the soil safe to grow vegetables in Cokeville?
The federal record around Cokeville is a meaningful one — 23 documented sites, mostly Nitrate entries (12), the nearest Underground Storage Tanks record about 0.2 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do gardeners stretch the season in Cokeville?
With about 118 frost-free days between hard freezes, Cokeville rewards the classic extension moves: floating row cover buys roughly two to four extra weeks at each shoulder — on this season that is a working window nearer 146 to 174 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 19 hard-freeze normal stretches the season without touching the calendar.
