‘King Tides’ to Bring ‘Extreme’ Surf to California Beaches, A coastal flooding advisory was in effect for parts of California Monday as “king tides” were expected to bring “extreme surf” to the area through Tuesday.
King tides occur when the earth, moon and sun are aligned and in close proximity, resulting “in maximum gravitation force on tidal cycles,” according to the National Weather Service.
The high seasonal tides could bring waves as high as 20-feet to central California beaches. They were also forecast to affect the San Francisco Bay Area, according to the weather service.
In addition to higher high tides that may result in coastal flooding, the phenomenon will also bring lower low tides, which could leave some boat keels touching harbor bottoms, federal forecasters said.
