Seattle is famous for its rainy days. There are lots, and many folks find that regrettable.
My opinion has long been that the sun comes out almost every day. Maybe only for a few minutes, and often just after sunrise or just before sunset, but it does shine.
It is worth watching for.
Today it rained moderately for much of the day, and rained hard for most of the rest, but the sun came out for a few minutes in the evening, and I grabbed my camera and went out in the backyard to catch the moss & lichen on the apple and cherry trees, still wet with rain, illuminated by almost horizontal sunlight.
