 Foghorn on Golden Gate Bridge

    Listen to Fog Horn on Golden Gate Bridge*

 

Simultaneously, 2 foghorns on the south tower of the Golden Gate Bridge sound together to make a single blast every 20 seconds, while the Golden Gate Bridge mid-channel fog diaphone sounds two blasts every 40 seconds.

 

Inbound ships heading into San Francisco Bay steer left of the foghorn on the south tower and right of the mid-channel fog diaphone.  Outbound ships stay to the right of the mid-channel fog diaphone.  Fog is most prevalent at the Golden Gate in July and August. 

 

The Point Bonita Light is 2.5 miles due west of the Bridge.
