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.
Gardening in the Willamette Valley. Valley-floor soils are often heavy clay that stays wet into spring, so raised beds help early crops. Slugs thrive in the long rainy season, and the summers are dry: water deeply from July until the fall rains return.
Frost date isn't planting date. The typical last frost in McMinnville and Newberg is April 15, but tomatoes wait until May 15, about 4 weeks later, because the soil is still too cold for them to grow. Why soil temperature matters.
How the season in McMinnville and Newberg compares
With 194 frost-free days, McMinnville and Newberg have the 35th-longest season of the 86 Oregon, Washington and Idaho towns we cover. They run from 72 days in McCall to 330 days in Brookings and Gold Beach.
The typical last frost here, April 15, is in the middle of the towns we cover in the Willamette Valley: 12 days later than Salem and 9 days earlier than Cottage Grove.
The gap between the typical last frost and the date it's over in 9 years out of 10 is 21 days, about average for the towns on this site. Frost after the typical date still happens about half the time, so plan on covering warm crops until May 6.
The season is long enough for every warm crop on our list, even pumpkins and sweet potatoes, to finish from a normal planting date.
For a fall and winter garden, sow carrots by August 6 and set out kale plants by August 20. Fall crops here are timed to the first frost (October 26 on average) and to shortening days.

Where these dates come from
The frost dates for McMinnville and Newberg come from the NOAA weather station at McMinnville Municipal Airport, about 3 miles east of McMinnville and about 11 miles southwest of Newberg, at 160 feet. It's an airport station, out on open ground, so a garden in town, on a slope or in a low spot can run a few days earlier or later.
They're NOAA's 1991–2020 climate normals: 30-year averages, not a forecast. How we pick each town's station.
