Despite western Washington's having a marine climate similar to many coastal cities of Europe, there are exceptions such as the "Big Snow" events of 1880, 1881, 1893, and 1916, and the "deep freeze" winters of 1883–1884, 1915–1916, 1949–1950, and 1955–1956, among others.
Napriek tomu, že Západný Washington má oceánske podnebie, podobne ako veľa pobrežných miest v Európe, vyskytli sa tu extrémy ako veľké množstvo snehu v rokoch 1880, 1881, 1893 a 1916 alebo zimy s hlbokými mrazmi v rokoch 1883–84, 1915–16, 1949–50 a 1955–56.
