Mean Sea Level Trends for Stations in Washington

Water-level records combine data on ocean fluctuations and vertical motion of the land at the station. The sea-level variations determined by these records include the linear trend, the average seasonal cycle, and the interannual variability at each station. Monthly data through the end of 2006 were used in the calculation, and all stations had data spanning a period of 30 years or more.

Station location, data, tide predictions, and other information are available for these and other stations. Choose from a list of stations presently in operation or from a list of all historic stations.
