October 29, 2026 — South Bay. A coastal flood warning has put San Diego Bay’s waterfront on alert, with potential effects extending to routes used by South Bay residents. The Port of San Diego warned that elevated water levels could flood low-lying roads, pathways and waterfront access points through Thursday, according to an October 28 City News Service report carried by NBC 7 San Diego.
South Bay bicycle route among vulnerable locations
The Port identified a section of the Bayshore Bikeway in South San Diego Bay, between State Route 75 and Flamingo Trail, among locations vulnerable to flooding. That matters to riders and commuters traveling around the bay from Chula Vista, National City and neighboring communities. The warning identifies a potential hazard; it does not mean the entire bikeway is closed.
Other reported locations at risk include sections of the downtown San Diego waterfront, where high tides have already caused temporary road flooding. The Port said elevated water could overtop seawalls and temporarily affect access, while the National Weather Service warned of possible shoreline erosion.
Planning a waterfront trip?
- Check Port of San Diego updates and local road or path notices before setting out.
- Do not ride or drive through standing water, even when it appears shallow.
- Use extra caution near seawalls, boat ramps and low-lying waterfront paths.
- Follow National Weather Service updates as the warning period ends and conditions change.
Why Chula Vista should pay attention
Chula Vista’s waterfront is becoming an increasingly important recreation and visitor destination. Keeping routes usable and clearly communicating temporary hazards is part of making the Bayfront welcoming to residents and visitors alike.
