Mean Tide Levels for Puget Sound, Washington
Mean Tide Level data is sometimes needed to estimate the tide level desired to launch or land at beaches with tide flats. Unfortunately many pocket sized tide tables don't include this data. While the daily tide data in your tide table books are only good for the year, constants such as the mean tide level are the same year after year.
We suggest looking at NOAA's list of mean tides, printing out this supplemental data, and tucking it into your tide book. The link provided goes right to mean tides for Oregon and Washington.
