Is San Francisco Bay Rough?
Splinter. The ocean off of San Francisco is notoriously rough, at least past the Faralon Islands (about 30 miles off shore). If you are heading to Hawaii, it usually smooths out once you are 60-100 miles off shore, but even that is variable. That is the Pacific!
Is San Francisco Bay contaminated?
Scientists now consider the most significant legacy pollutants found in the Bay to include mercury and PCBs, which are found in relatively high concentrations in Bay sediments and are the principal cause of fish consumption advisories throughout the San Francisco Estuary.
How deep is the water in San Francisco Bay?
about 12-15 feet deep
The average depth of the bay is about 12-15 feet deep. Heck, between Hayward and San Mateo to San Jose it averages 12 to 36 inches. So much for that bridge! With that said though, the water surrounding Alcatraz is on the deeper end of the scale, but still, it’s just an average depth of 43 feet.
Are there currents in bays?
The currents in the Bay are generated by the tides – currents are strongest during and shortly after full moon and new moon when tide differences are highest. It is important to learn how to read tide and current tables. Bay Area Sea Kayakers provides a helpful overview on how to plan for tides and currents.
Can you swim in the SF Bay?
Beaches in San Francisco are not safe for swimming, and that goes double for Ocean Beach, which has the worst rip currents and most drownings. More information on rip currents from the United States Lifesaving Association.
How deep is the water under the Golden Gate Bridge?
The depth of water under the Golden Gate Bridge is approximately 377 feet (or 115 meters) at its deepest point. The US Geological Survey, with other research partners, have mapped central San Francisco Bay and its entrance under the Golden Gate Bridge using multibeam echosounders.
Is it safe to swim in SF Bay?
Beaches in San Francisco are not safe for swimming, and that goes double for Ocean Beach, which has the worst rip currents and most drownings.
Why is San Francisco water so dirty?
The brown in the Bay Waters is largely a plume of sediment, the raw material necessary to rebuild wetlands and maintain their health. That sediment, though, is mixed up with pollutants — toxic mercury from old mines, Lester McKee, a scientist with the San Francisco Estuary Institute tells News Group.
Is Alcatraz water shark infested?
The waters between North Beach and Alcatraz are not shark infested, as urban legends would have you believe. Most sharks can’t live in the bay’s fresh water, as their fatty livers aren’t functionally flotational without salination.

How strong is the current in the San Francisco Bay?
The currents in San Francisco Bay are generated by the tides. At several locations in the Bay, currents can be as strong as six knots. As a recreational paddler, you paddle about three knots—four if racing or terrified.
Are rip currents stronger than backwash?
This strong tidal flow is typically more powerful than rip currents and can carry a person far off shore. An undertow occurs when the uprush (or swash) and the resulting backwash of large waves happen in quick succession.
What is the water temp in the Bay Area?
The seasonal range of water temperature in the Bay is from January’s 53 °F (12 °C) to September’s 60 °F (16 °C) when measured at Fort Point, which is near the southern end of the Golden Gate Bridge and at the entrance to San Francisco Bay.
