May Creek, Washington, sits in USDA hardiness zone 8b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Among the crops suited to this profile: cabbage, fig, california poppy, and collard greens. The site-level story — soil, sun, drainage — decides the rest.
Even in May Creek, no two yards are alike.

Every figure names the dataset it came from. Hard-freeze dates are this town’s own 28°F normals: light frosts run a few weeks past them, and tender transplants usually wait 2–3 weeks after the last hard freeze.
Hardiness Zone Range
Zone 8b is May Creek's average, not your lot's — a low corner or a tree line moves it. Against May Creek's 259-day season, see what your own ground reads.
Your town runs its own season
May Creek's own 30-year record measures about 259 days between 28°F killing freezes — 51 days longer than Snohomish County's ~208. Both are measured records, not estimates.
That gap is the whole reason a county average can mislead here. Plant against May Creek's ~259-day season rather than the county figure — and the sun, slope and cold-air drainage on your specific lot move it again.
NOAA Regional Climate Centers ACIS (1991–2020), 30-year daily minimum record. Both figures are measured records — this town’s own and its county’s. A town with no record of its own is absent here rather than estimated.

What this means for growing in May Creek
Each reading below is measured for May Creek itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredMay Creek runs about 259 days between hard freezes — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.

Winter hardiness
MeasuredMay Creek sits in USDA hardiness zone 8b.
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 May Creek is in
May Creek sits in the Puget Lowland — EPA Level III, inside the wider Marine West Coast Forest. That is read at May Creek's own centroid, and it is not what its county reads: Snohomish County is mostly North Cascades. The wider page above you is answering a different question about different ground.

Is it too late to plant in May Creek?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Feb 8; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 8 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 22 — long-season crops need about 90 days of runway, quick greens only 30. A long window like this one runs successions deep into fall — and even its last weeks take quick greens and garlic.

A note from Gnorman
What an experienced grower watches for around here
In and around May Creek, two things run higher than the national average within ~10 miles of May Creek — Mining (62 sites) and Superfund (3 sites). That's not a problem with your land — it's information about it.
Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).

Your land is one point inside May Creek
Everything above resolves to May Creek as a whole — and this is a town whose own 30-year record already runs a season its county’s does not. Your parcel sits at one point inside even that. 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 May Creek
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 May Creek’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 May Creek
When does frost risk typically end in May Creek?
The last hard freeze (28°F) in May Creek typically lands around Mar 8, 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 Mar 29.
When is the first frost in May Creek?
The first hard freeze (28°F) in May Creek typically arrives around Nov 22, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 8, so the watching starts about Oct 23 — about 259 days after the spring freeze cleared.
How long is the growing season in May Creek?
Measured between 28°F hard freezes, May Creek sees about 259 frost-free days — roughly Mar 8 through Nov 22, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 29 to Nov 8, about 224 days.
Is the soil safe to grow vegetables in May Creek?
The federal record around May Creek is a meaningful one — 143 documented sites, mostly Mining entries (62), the nearest Nitrate record about 0.3 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 I protect my plants from frost in May Creek?
From about Oct 23 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Nov 22 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Nov 22. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
