Part of Santa Monica Bay closes to unapproved boats

The U.S. Coast Guard is closing part of Santa Monica Bay to unapproved boats and people during the 2026 World Cup, creating a temporary security zone offshore of Los Angeles International Airport. The rule takes effect June 15, 2026, and runs through July 12.

For boaters, charter operators and anyone moving near the shoreline, the practical change is simple: entry is barred unless the Captain of the Port, Los Angeles-Long Beach, authorizes it. The agency says the restriction is there to protect public safety and prevent sabotage or terrorist acts near the airport.

A hard line on the water

The zone covers navigable waters offshore of LAX, from the surface to the bottom, so it acts like a real perimeter rather than a warning on paper. The Coast Guard ties the restriction to the World Cup because the event will bring more people and activity through the area.

That matters most for the everyday users of the bay, the people whose routes are usually casual and open until a rule like this drops a boundary across the water. A familiar stretch can turn into a no-entry zone for several weeks.

The short window for access

The agency will use actual notice for enforcement from June 11 through June 15, then the rule runs without actual notice until July 12. Anyone who needs to cross the zone has only a brief window to sort out permissions before the restriction fully hardens.

The closure is temporary, but it changes the terms of movement along one of the best-known pieces of coastline in Southern California. For the weeks it is in force, Santa Monica Bay is not open by default.
