Coast Guard enforces safety zone for Big Bay Boom fireworks in San Diego

The U.S. Coast Guard is enforcing a temporary safety zone in San Diego Bay for the Big Bay Boom Fourth of July Fireworks event on July 4, 2026. The restriction applies from 8 p.m. to 10 p.m. and covers specific areas of the bay identified in existing regulations.

Why it matters: This is a routine annual safety measure to manage maritime traffic during a large public event. It ensures that emergency channels remain clear and prevents accidental collisions between spectator boats and the fireworks launch vessels or official patrol craft. While it restricts access to specific parts of San Diego Bay for two hours, it does not change long-term navigation rules.

Who it affects

• Boat owners and mariners planning to be in San Diego Bay on July 4, 2026, between 8 p.m. and 10 p.m.
