Quick,
My daughter and family lived in the great state of Washington for a while, and the wife and I went to visit. We were advised to bring a light jacket or sweater, as it was apt to be chilly, (60 or so), much of the time.
That was the case the day we arrived, but a couple days late it got up to 93. Felt fine to me, but most folks were about to die from the heat. Few had air conditioning, and I think Walmart sold out of fans pretty fast. The day we left it was back to about 60 degrees.
Quite frankly, there is nothing comfortable about extreme cold or heat, I'm just more used to the latter.
Stay close to the stove, it will warm up soon, or so says Al Gore.
