Savoonga, Alaska, sits in USDA hardiness zone 4a — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
Expect okra, cranberry, cilantro, and zucchini to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Even in Savoonga, 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 Savoonga 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 Savoonga
Each reading below is measured for Savoonga itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsSavoonga runs about 118 days between hard freezes (read from Nome Census Area, the closest normal to Savoonga) — 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.

Winter hardiness
MeasuredSavoonga 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.

Is it too late to plant in Savoonga?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Apr 26; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 24 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 19 — long-season crops need about 90 days of runway, quick greens only 30. Even here the calendar’s edges hold value: thirty-day greens late in the window, then garlic and a rested bed for spring.
Environmental Check
No contamination sources found near Savoonga
We checked 9 federal environmental databases and found no recorded contamination sites in this area. A clean starting point for growing.
Your land is one point inside Savoonga
Everything above resolves to Savoonga as a whole — one PHZM band, read across 4K acres, with hard-freeze dates borrowed from Nome Census Area’s record because no 30-year normal resolves at this city’s own centroid. 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 Savoonga
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 at Nome Census Area’s record, because none resolves here; 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 Savoonga
When does frost risk typically end in Savoonga?
The last hard freeze (28°F) in Savoonga typically lands around May 24, 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 14.
When is the first frost in Savoonga?
The first hard freeze (28°F) in Savoonga typically arrives around Sep 19, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 5, so the watching starts about Aug 20 — about 118 days after the spring freeze cleared.
How long is the growing season in Savoonga?
Measured between 28°F hard freezes, Savoonga sees about 118 frost-free days — roughly May 24 through Sep 19, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 14 to Sep 5, about 83 days.
Is the soil safe to grow vegetables in Savoonga?
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 Savoonga. 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 gardeners stretch the season in Savoonga?
With about 118 frost-free days between hard freezes, Savoonga 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 24 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Savoonga's scale — its 4a band and its 118-day season. Your yard writes its own version of Savoonga's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
