McCloud, California, sits in USDA hardiness zone 7b — a zone band wide enough that plant choice, not possibility, is the interesting question.
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 McCloud, 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 McCloud 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 McCloud
Each reading below is measured for McCloud itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredMcCloud runs about 172 days between hard freezes — a moderate growing season.
There is room for the full run of cool-season crops plus a warm-season main crop, but the calendar is tight enough that a late spring or early fall frost still decides how much finishes.
Time warm-season transplants to your last hard freeze, and a few weeks of season extension turns a near-miss harvest into a sure one.

Winter hardiness
MeasuredMcCloud sits in USDA hardiness zone 7b.
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 McCloud is in
McCloud sits in the Cascades — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at McCloud's own centroid, and it is not what its county reads: Siskiyou County is mostly Klamath Mountains/California High North Coast Range. The wider page above you is answering a different question about different ground.

Is it too late to plant in McCloud?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Mar 30; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 27 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 16 — long-season crops need about 90 days of runway, quick greens only 30. The tail of the season still works: sixty-day crops into late summer, quick greens after, garlic last of all.

A note from Gnorman
What an experienced grower watches for around here
In and around McCloud, two things run higher than the national average within ~10 miles of McCloud — Mining (8 sites) and Brownfields (57 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.
Brownfields: Brownfield sites are former commercial or industrial properties where legacy soil contamination (heavy metals, PAHs, petroleum compounds) may persist.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.
Check EPA brownfield remediation status — many sites have completed cleanup with institutional controls.

Your land is one point inside McCloud
Everything above resolves to McCloud as a whole — one PHZM band and one 28°F frost record, read across 2K 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 McCloud
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 McCloud’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 McCloud
When does frost risk typically end in McCloud?
The last hard freeze (28°F) in McCloud typically lands around Apr 27, 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 May 18.
When is the first frost in McCloud?
The first hard freeze (28°F) in McCloud typically arrives around Oct 16, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 2, so the watching starts about Sep 16 — about 172 days after the spring freeze cleared.
How long is the growing season in McCloud?
Measured between 28°F hard freezes, McCloud sees about 172 frost-free days — roughly Apr 27 through Oct 16, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 18 to Oct 2, about 137 days.
Is the soil safe to grow vegetables in McCloud?
The federal record around McCloud is a meaningful one — 72 documented sites, mostly Brownfields entries (57), the nearest Brownfields record under a tenth of a mile 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 McCloud?
From about Sep 16 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 Oct 16 (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 Oct 16. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at McCloud's scale — its 7b band and its 172-day season. Your yard writes its own version of McCloud's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
