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 Eugene is April 11, but tomatoes wait until May 15, about 5 weeks later, because the soil is still too cold for them to grow. Why soil temperature matters.
How the season in Eugene compares
With 195 frost-free days, Eugene has the 34th-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 11, is in the middle of the towns we cover in the Willamette Valley: 8 days later than Salem and 13 days earlier than Cottage Grove.
Late frosts are harder to predict here than in most towns. There are 28 days between the typical last frost and the date it's over in 9 years out of 10, against 19 for a typical town on this site, so keep frost cover handy until May 9.
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 23 on average) and to shortening days.

Where these dates come from
The frost dates for Eugene come from the NOAA weather station at Eugene Mahlon Sweet Airport, about 9 miles northwest of Eugene, at 350 feet. It's the closest weather station to Eugene with NOAA's 1991–2020 frost records. 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.
