The harbor sits at the edge of high tide
The city's June 2026 king tide advisory lists the neighborhoods most likely to flood: Newport Island, Balboa Island, the Finley Tract, Lido Village, Balboa Village, Lafayette Avenue, the Peninsula and parts of the Marcus, River and Lake Avenue area. Crews install flood-protection gap boards on Balboa Island, run pumps and place sandbags during those tides.
