West-side valleys. The Willamette Valley, Puget Sound and southern Oregon valleys. Long frost-free seasons, but soil stays cold and wet into May, so warm crops wait for warm soil, not just the last frost.
Frost dates are 1991–2020 NOAA climate normals for Portland-Troutdale Airport (9 m elevation). Gardens in cold hollows or at higher elevation can frost later in spring and earlier in fall.

Dates are a guide, not a guarantee. Check the soil before planting: cool-season crops need it workable and not soggy; warm-season crops need it warm. A $10 soil thermometer pays for itself. Unfamiliar terms are explained in the glossary.
