Swimming in Aquatic Park

South End Rowing Club is located on Aquatic Park in San Francisco, where swimmers can enjoy a protected cove and private beach for easy access. 


Swimming in the San Francisco Bay can be a challenging environment thanks to strong tides, boat traffic, sea life, and water temperatures ranging from under 50 degrees F in the winter months to the low 60 degrees F over the warmer months.


The resources below are available for swimmers to learn more about safely swimming in Aquatic Park and the surrounding areas.


Bay tides

Two important tidal terms to understand when doing a swim (whether inside or outside of the Cove): ebb and flood. 


Ebb is when the water is flowing out of the Gate towards the Pacific Ocean. 

Flood is when the water is flowing into the Bay from the Pacific Ocean. 


“Swimming against the current” means that you are swimming west (towards the Gate) during a flood or swimming east (towards the East Bay) during an ebb. 


The club has handy “tide books” that document the tides and current predictions for the entire year. There are two books in the Day Room and in each of the locker rooms. Learn how to read these. Luckily, Muni Pier and the Breakwater offer a lot of protection from the full effects of the currents when you are in the cove, yet even so, they are still noticeable. Do not swim outside the cove if you do not understand the tides and currents. View the Tides & Currents Slides (PDF).


The tides and currents are very important part of swimming in the Bay. Please watch this video to learn more!

Common Aquatic Park swim routes

There are many possibilities of swims you can do in our playground, Aquatic Park Cove (“The Cove”)


Swimming in the bay is always at your own risk. You are NOT allowed to cross the shipping lane without boat support and contacting Vessel Traffic for legal and safety reasons.


Ultimately, you are responsible for your own safety.


Inside the Cove

Buoy line


The buoy line runs along the length of Aquatic Park, from the just west of the Dolphin Club dock to a rectangular buoy with a flag on it at the western most end of the cove. It is known simply as “The Flag.” Many triathletes swim up and down the buoy line over and over again which can make it feel like Grand Central Station sometimes. This is a great place to remain for those who have never swam in the Bay as it’s relatively safe as it’s proximity to shore makes it have less effects from the currents.


Cove swim

A “cove” swim is anything that involves going along the buoy line to and along Muni Pier and the Opening and back to the club or the reverse direction (depending on the currents). Distance traveled depends on how tight you make your cove lap as everyone does it differently. Take caution swimming along Muni Pier as it's old and crumbling.

Outside the Cove

SERC does not recommend members swimming outside the Cove. If you do so you swim at your own risk and always swim with a buddy / escort.
