Each reading below is measured for Scammon Bay itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Winter hardiness

Measured

Scammon Bay sits in USDA hardiness zone 4b.

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.

Your land is one point inside Scammon Bay

Everything above resolves to Scammon Bay as a whole — one PHZM band and one 28°F frost record, read across 300 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 city 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 Scammon Bay

The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals, with the labelled statewide window where none resolves; 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 city grain anywhere on this page — there is no city-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 Scammon Bay

When does frost risk typically end in Scammon Bay?

Scammon Bay has no hard-freeze normal of its own, so it follows Alaska's statewide window: the middle half of counties see their last spring hard freeze (28°F) around Apr 16 - May 15 and their first fall hard freeze around Sep 24 - Oct 29, per NOAA Regional Climate Centers ACIS (1991–2020). Frost dates shift with elevation and local microclimate, so watch your own site's cold pockets. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.

Is the soil safe to grow vegetables in Scammon Bay?

No database can certify soil, but the federal record here is clean: we checked all 9 federal contamination source types and found no documented sites within the search radii around Scammon Bay. That means nothing is on record — not that the land is certified clean — so a one-time soil test is still the way to know your own yard's history.

How do I protect my plants from frost in Scammon Bay?

As the season closes around Alaska's statewide first fall hard freeze (28°F) near Sep 24 - Oct 29 (NOAA Regional Climate Centers ACIS (1991–2020)), 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 the first hard night. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
