About Sequim
Sequim is known for its lavender farms, and lavender's love of dry, sunny summers says a lot about the town's weather. In the Olympic rain shadow it gets only about 16 inches of rain a year, so plan on watering more than gardens around Puget Sound do.
Chance of frost through the year
Frost over in 9 years out of 10: after May 7

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 Olympic Peninsula and coast. Rain varies hugely here: Forks and the outer coast are among the wettest places in the country, while Sequim and Port Townsend, in the Olympic rain shadow, are some of the driest spots west of the Cascades. Summers are cool everywhere, so early, cool-tolerant varieties do best.
Frost date isn't planting date. The typical last frost in Sequim is April 21, but tomatoes wait until May 15, about 3 weeks later, because the soil is still too cold for them to grow. Why soil temperature matters.
How the season in Sequim compares
With 182 frost-free days, Sequim has the 41st-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 21, is the latest of the towns we cover in the Olympic Peninsula and coast: 51 days later than Port Townsend and 1 day later than Forks.
The gap between the typical last frost and the date it's over in 9 years out of 10 is 16 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 7.
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 20 on average) and to shortening days.
