The wind dies near the shore much sooner than out in the middle. Stay clear of all vessels and do not insist on your right-of way. Fog pushing through the Golden Gate can reduce visibility to near zero and make it difficult to locate your launching spot or any land in general. 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.
