What Grows in Crescent Lake, Oregon

The last hard freeze (28°F) in Crescent Lake typically lands around Jun 3, 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 24.

The first hard freeze (28°F) in Crescent Lake typically arrives around Sep 30, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 16, so the watching starts about Aug 31 — about 119 days after the spring freeze cleared.

Measured between 28°F hard freezes, Crescent Lake sees about 119 frost-free days — roughly Jun 3 through Sep 30, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 24 to Sep 16, about 84 days.

The federal record around Crescent Lake is a meaningful one — 11 documented sites, mostly Underground Storage Tanks entries (9), the nearest Underground Storage Tanks 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.

With about 119 frost-free days between hard freezes, Crescent Lake 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 147 to 175 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the Jun 3 hard-freeze normal stretches the season without touching the calendar.
