Yessir, top 15 on the list. all in the PAC NW, this is indeed the land of Goretex & rubber sole shoes. Particularly noticeable today while attending grandaughter's soccer game in Olympia. Durned chilly, winds gusting 10-15 mph, gentle intermittent mist, occasional sun breaks were welcomed.
On the other hand, Seattle's #2 on the list of best major city air quality, not a bad trade, seeings as how we have a little over 5 million people living on the Western Slopes of the Cascade Mts. It's close to 9 million if you include Metro Portland, Ore, & Vancouver BC . I'll take a little rain now & then.

p.s. Joe, there's no doubt Bellingham, Wa & surrounds is one of the most beautiful places I know.
