Many, but not all, beaches have live webcams that are available to view online. Large beaches located in close proximity to a major city or harbor are the most likely to have webcams, but even some smaller beaches have them.
Examples of live webcams in the U.S. include popular beaches like Fort Lauderdale and Santa Barbara as well as some more remote areas, such as the beaches of LaPush, Washington.
BeachCamUSA.com is one website that offers live footage from webcams on many beaches across the country. This includes boardwalk cameras from places like Ocean City, Maryland, and live cameras at popular beach hotels in North Carolina and Hawaii.
