About The Dalles
The Dalles sits on the Columbia at the east end of the Gorge, where the wet west side gives way to dry country. The orchards around town make it one of the country's top sweet cherry areas.

East-side valleys. The Columbia Basin, Yakima Valley, Boise's Treasure Valley, Lewiston and other low valleys east of the Cascades. Hot, dry summers and quick spring warm-up. Warm crops go in earlier than west of the Cascades, and irrigation matters more than rain.
Gardening in the Columbia Gorge and eastern Oregon. Summers are hot and dry, so plan on irrigation. In the Columbia Gorge, steady wind dries plants out quickly, so stake tall crops and use windbreaks; the higher valleys around La Grande, Baker City and Joseph have shorter seasons.
Frost date isn't planting date. The typical last frost in The Dalles is April 11, but tomatoes wait until May 1, about 3 weeks later, for warmer soil and less risk of a late frost. Why soil temperature matters.
How the season in The Dalles compares
With 198 frost-free days, The Dalles has the 33rd-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 the earliest of the towns we cover in the Columbia Gorge and eastern Oregon: 9 days earlier than Hood River and 47 days earlier than John Day.
The gap between the typical last frost and the date it's over in 9 years out of 10 is 17 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 28.
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 The Dalles come from the NOAA weather station at The Dalles Municipal Airport (Dallesport, WA), about 2 miles north of The Dalles, at 240 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.
