“Beachgoers are said to be a white woman with blue hair wearing a bathing suit and the other a black man,” the statement said.
A man who was fishing nearby reported seeing the woman fall into the water and the man jumping in pursuit, the statement added.
A lifeboat crew and helicopter crew were deployed as part of the search, officials said.
Pismo Beach is located just over ten miles from San Luis Obispo on the central California coast.
