Product: Survey Coverage Map • Annual Summary • Seasonal Volume Change • Seasonal Beach Width

Seasonal (quarterly) variation of the observed mean beach width. The seasonal beach width maximas can occur in either the summer of fall quarters, and minimas in the winter or spring quarters, depending on when the first and last significant North Pacific storm wave events of the year occur.

Beach years that included significant El Nino winters are highlighted in grey.

The beach width is the alongshore averaged distance from a prescribed back beach line to the the mean sea level shoreline location.

Contiguous seasons with survey data are connected by black lines.

Widths are based on quarterly mean beach profiles.
