Is It Safe to Swim in the Redwood Shores Lagoon?

While the Redwood Shores Lagoon is typically used for boating and providing a habitat for wildlife, it is not recommended for swimming due to various reasons. This article explores the general safety concerns, the presence of jellyfish, the historical swimming experiences, and alternative options for those eager to swim in the area.

The Safety Concerns of Swimming in the Redwood Shores Lagoon

The authorities and local health departments advise against swimming in the Redwood Shores Lagoon. The water quality can vary due to factors like runoff and the presence of local wildlife. It is crucial to check for any posted signs or swimming advisories before entering the water. For instance, Redwood Shores regularly updates its guidelines based on current conditions.

Experiences and Advisories

A recent resident shared their experience, stating that they kayak regularly in the lagoon but avoid swimming there altogether due to frequent jellyfish sightings. However, they noted that jellyfish are more common in the evening and in the center of the lagoon, with some people swimming around the side beaches successfully. Despite these risks, the possibility of finding suitable areas to swim remains.

The author of this article, having lived in the Bay Area, has first-hand experience of swimming in the lagoon. They mention the cold temperatures in the winter, requiring a wetsuit, and the warmth of the summer, allowing swimming without it. They also suggest that the lagoon is a good place to train for open water events, but warned that it can become monotonous over time.

Alternative Swimming Options

For those looking to swim in the vicinity, Foster City's Aquatic Park has a designated swimming beach. There is also a strong possibility that other nearby parts of Foster City, including areas towards Redwood Shores, have additional swimming beaches. This provides a safer and more monitored option for those who prefer to swim.

Visitors should also be aware of the aquatic life in the area. Leopard sharks and jellyfish are commonly reported, along with the presence of grates under some of the bridges, which can offer protection from strong currents. However, it's important to note that the lagoon and nearby areas can have shallow depths that are risky for drowning.

Conclusions and Recommendations

While swimming in the Redwood Shores Lagoon is not recommended due to safety concerns and varying water quality, there are safer and monitored alternatives nearby. It is always best to rely on official guidance from local authorities or health departments before engaging in any water activities. Proper research and preparedness are crucial for a safe and enjoyable swimming experience.
