I pulled this from an article I just read.
I found out that Seattle doesn’t really get that much rain compared to most U.S. cities. In fact, Seattle ranks 44th among major U.S. cities in average annual rainfall, getting approximately 38 inches annually. Cities that get more rainfall than Seattle include such as Houston Texas (48 inches), New Orleans (60 inches), Mobile AL (65 inches), Memphis (52 inches), Nashville (48 inches), and pretty much every major city on the eastern seaboard, such as New York (43 inches), Philadelphia (41 inches), Miami (58 inches), and Boston (44 inches)
Here is the thing about Seattle. The weather is perfect. I lived there and while it does rain more than Los Angeles, it is not a rainy place, not like New York, or Vermont where I swear unless it is snowing it is raining. Pissing down rain actually. In Seattle when it rains, it clears up and sunshine is there. So why not call it the sunshine state? Oh cuz Florida-which actually has more rain than Seattle-has that name.
