Coast. Mild winters but cool, foggy summers. Frost is rarely the problem; warmth is. Pick early, cool-tolerant varieties of tomatoes and squash.
Gardening in the Oregon Coast. Cool, foggy summers and steady wind hold crops back more than frost does. Shelter warm crops from the wind, pick early, cool-tolerant varieties, and expect salt spray in gardens right by the shore.
Frost date isn't planting date. The typical last frost in Astoria is March 26, but tomatoes wait until May 20, about 8 weeks later, because the soil and nights are still too cold for them. Why soil temperature matters.
How the season in Astoria compares
With 230 frost-free days, Astoria has the 15th-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, March 26, is in the middle of the towns we cover in the Oregon Coast: 54 days later than Brookings and Gold Beach and 27 days earlier than Tillamook.
The gap between the typical last frost and the date it's over in 9 years out of 10 is 23 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 April 18.
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 (November 11 on average) and to shortening days.

Where these dates come from
The frost dates for Astoria come from the NOAA weather station at Astoria Regional Airport, about 3 miles southwest of Astoria, at 10 feet. It's the closest weather station to Astoria 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.
