San Diego Bay Waterfront Faces Temporary Flooding from King Tides and Weather Conditions

Port officials warn residents of potential street closures near Harbor Drive and other low-lying areas as high tides combine with weather events.

Officials with the Port of San Diego are warning the public to expect temporary street flooding along portions of the waterfront as unusually high tide levels combine with seasonal weather patterns and anticipated rainfall. The National Weather Service has issued a coastal flooding advisory for the area.

Several bayfront locations have already experienced flooding impacts in late October, with a stretch of West Harbor Drive closing temporarily on October 26 and 27 due to water overtopping seawalls. The closure, which affected the area between Market and Front Streets, lasted about an hour before water levels dropped and the road reopened.

Multiple waterfront zones are considered particularly susceptible to flooding, including sections of North Harbor Drive near Laurel Street in the Embarcadero, parts of the Embarcadero Marina Park North walkway and parking areas, Pacific Highway at Laurel Street in downtown, Anchorage Lane near Canon Street in Point Loma, and portions of the Bayshore Bikeway in South San Diego Bay. Officials caution that elevated water may block access to waterfront destinations, disrupt vehicle traffic, and pose risks to those walking or cycling.

Port commissioners declared a local emergency during their October 13, 2026 meeting to facilitate coordination with government partners at multiple levels. The agency is implementing preventive measures including storm drain inspections, installation of backflow prevention devices, enhanced monitoring of flood-prone locations, and coordination with neighboring municipalities on emergency management.

Authorities are urging residents to allow additional travel time when visiting bay areas during peak tide periods, follow posted warnings and road closures, and secure outdoor items that could obstruct drainage systems. The public can report safety concerns by calling 911 or notifying the Port directly through its online service portal. Port staff and Harbor Police will continue tracking conditions and sharing updates via social media throughout the elevated tide season.
