Portland, Oregon planting calendar
Cool, wet winters; dry, warm summers; cool nights slow warm-season crops in spring and early summer. Frost-free season about 214 days.
Climate assumptions
USDA zone 8b–9a. The zone describes winter minimums only; the maritime climate gives a long, mild, wet spring and a dry summer.
Average last spring frost: Apr 5 ± 14 days
Average first autumn frost: Nov 5 ± 14 days
Status: primary region, fully checked.
Caveats
- Soil stays cold and wet into April; transplant warm-season crops when night temperatures reliably exceed 10 °C (50 °F), often mid-May, not at the average last frost.
- Summer drought means irrigation is required for most vegetables from June to September.
- Microclimates (hills, urban heat, river valleys) shift frost dates by two weeks or more.
A hardiness zone describes winter minimum temperature; it is one input, not a vegetable planting schedule. Why frost dates matter more →
