NOAA's 1991-2020 median first 32°F night is November 23 at Seattle and October 12 at Spokane; winterize by September 28, two weeks ahead of the earlier date. By our personal watercraft rule Seattle stays on the water through August and Spokane through August, then 3 months of wetsuit weather follow at Seattle. 26 Washington listings offer indoor or climate-controlled space.
7 at Seattle (September to June) and 7 at Spokane (September to June), plus 3 and 3 months of wetsuit weather. Those off the water months hold 45.2 of the 45.4 inches of snow Spokane averages a year (100%), which is the load on a cover or carport roof. At Seattle a personal watercraft is on the water from July to August (2 months), against 2 at Spokane.
Of 30 live Washington listings, 26 list indoor space and 0 climate-controlled units, against 26 outdoor and 24 covered. By city: Seattle (11 listed, 7 indoor), Vancouver (5 listed, 5 indoor), Tacoma (4 listed, 4 indoor) and Everett (3 listed, 3 indoor). Most indoor listings: Seattle (7), Vancouver (5) and Tacoma (4). Ask whether indoor means heated; listings span 10 cities in all.
At Spokane, 5 months average a low at or below 32°F, all of them off the water months by our personal watercraft rule. Spokane logs 132.0 nights at or below 32°F and 2.2 at or below 0°F a year; December, the coldest month, averages 24.3°F and is off the water for a personal watercraft.
After the last frost. The median last 32°F night is March 2 at Seattle and April 26 at Spokane; the last 28°F hard freeze comes around February 4 and April 6. Our rule makes July the first month on the water at Seattle and July at Spokane. That month Seattle averages a 56.8°F low and a 77.4°F high. Reverse each winterization step first.
