Yeah this is the absolute best time to come here. Reliably amazing starting in July, normally until around Halloween. Just don't come in Dec/Jan when the winds are gusting to 60 mph and the trees are coming down on houses and there is no power
(actually my part of the island had a pretty mild winter in that sense this last year). I kinda also like that part of the year too though.....
That weather Tues night into Wed was pretty sporty if you were still in SEA. Was driving from hotel into a sim in the AM and there was all kinds of lightning. Normally get the little boomers up in the straits/olympics, and then the bigger boomers of course over the cascades and east, not so much down the puget sound. Aside from real isolated ones in the spring when the weather gets crazy for a few weeks in Mar-Apr.
