Washington State: I have lived on both sides of the state. I'm on the dry side now.
The Pacific Northwest (the wet side) has a mild summer. Only a weeks worth of above 90 degree days scattered throughout a short dry summer. The rest of the year it rains.
The Inland Northwest (the dry side) I'm up in the hills and we have 6 to 7 months of winter. It can start snowing mid October and thaws late April.
Spring (mosquito season), Summer (wasp season), and Fall (stinkbug season) are crowded into the other 5 to 6 months of the year. If you want to see colorful fall leaves... Well, we mostly only have evergreen trees. But, here in the hills the leaves on the bushes do start turning a nice red in mid August.
