This fog pattern usually causes the wind to die suddenly. Sail conservatively, head for shore sooner, rather than later. Wind is usually side, onshore. The water is fairly shallow especially at low tide. Be courteous to other beach users.
Dripping equipment can be a chilling experience to a sun bather.
This area records some of the highest winds in the area. Questionable water quality from anecdotal evidence only. Watch for Golden Gate Transit ferries entering and leaving the ferry terminal. Do not try to sail in front of or behind a ferry. Stay clear of the harbor seals.
