I lived in Washington State for 5 years (1976-81). Grew up in Northeast of USA (NYC -DC).
First years in Seattle, I felt something miss one season. My experience to have 4 season in Northeast of USA. Most bother me that I feel something miss on season - not sure which miss one season from fall or winter or spring season. During late august to late winter season, almost everyday cloud. It was very light rain as on/off. Big different from norttheast - pour rain, tropic storm and thunderstorm. Everyday cloud made me feel blue mood because lack of sun light. Sometime, I saw beautiful blue sky. Most beautiful to view mountains. Most time, temp is upper 40's or lower 50's but with humid made me feel "colder" as lower 30's or upper 20's. Not like Northeast of USA, feel right temp at middle 30's or lower 40's.
I love late spring to summer time in Seattle/Northwest because almost no humid. Not really need to use Air Condition. Feel good with this weather condition better than Northeast of USA. I never like heatwave, higher humid season. Most time, upper 70's in high.
I never forget what happen on May 18, 1980. Big erupted from Mt St Helen. I was there.
June 1981, I moved to east coast. I drove out of Washington State's border made me cried. Not know when I will come back. Still not visit Washington State since I left.
What is my most enjoy in Washinton State - water sport (windsurfing and swim long distance from Bellevue or Seattle to Mercer Island) and ski at mountain. Learn Rodeo at Tri-Cities (Richland).
What I dislike - feel blue mood with higher humid in fall/winter season, deaf at bar, stab on back, they think I am gay or Bi.
