The beaches are not closed. The beaches are open year round everyday. The beaches are closed for cleaning and maintenance everyday from midnight to 5am, and are closed on occasion for weather related issues (usually thunderstorms and only for a few hours or so), but other than that they are always open.
All 10 miles of OC's beaches are accessible, public, guarded (until 23 September this year) and free!
Have a great time in OC!
