Abstract: Visual surf observations were begun in 1954 at twenty-seven stations, located at various points on the Atlantic, Gulf, and Pacific coasts of the United States, under a cooperative surf observation program between the U. S. Coast Guard and the Beach Erosion Board, Corps of Engineers, U. S. Army. These data sets are summarized for a monthly basis in tabular form and on a yearly basis as cumulative frequency curves for each station. The most common observed surf heights were between 1 and 6 feet, with few exceeding 7 feet. The most common surf periods were between 4 and 8 seconds. The effects of hurricanes on surf conditions along the Atlantic and Gulf coasts were studied. Hurricanes Connie, Diane, and Brenda caused an increase in the significant heights of the surf of 3 to 8 feet, resulting in surf heights of 5 to 10 feet. The surf periods were altered by as much as 7 seconds. A comparison of observed surf and wave hindcast statistics was made for Grand Isle, Louisiana. These data are readily applicable in the study of shore erosion, littoral transport, and the design of shore structures.
