County CEO Frank Kim and Supervisor Lisa Bartlett confirmed the planned closures, which include beach parking lots, for Saturday and Sunday.
The affected county-operated beaches include: Aliso, Capistrano, Salt Creek, Baby Beach, Bayside, Camel Point, Poche, Strands, Table Rock, Thousand Steps, Treasure Island and West Street.
The decision to temporarily ban visitors to the locations follows a state recommendation intended to slow the resurgent spread of COVID-19.
Officials in Newport Beach, Laguna Beach, Huntington Beach and Seal Beach had already announced plans to close their cities' respective beaches for the holiday. In Newport Beach, two seasonal lifeguards tested positive for the coronavirus, and nearly two dozen others were placed in quarantine.
The surge comes as Americans head into a Fourth of July weekend that health officials warn could add fuel to the outbreak by drawing big crowds. Many municipalities have canceled fireworks displays. Beaches up and down California and Florida have also been closed.

The Orange County beach closures follow a county order Wednesday closing all bars in the city, an order that was also put in place later in the day by Gov. Gavin Newsom, affecting 19 counties, including Orange County.
The county order affects all bars, pubs, breweries and brew pubs that do not offer dine-in meals. Establishments serving dine-in food can only sell alcohol in the same transaction as a meal.
The closure order was expected ahead of the holiday weekend, given similar action already taken in surrounding counties of Los Angeles, San Diego and Riverside. Also, Ventura and Santa Barbara counties have announced beach closures.
