Bay Area Beachgoers Should Brace For Unusually High Tides

Bay Area shores are expected to be hit with unusually high tides known as “king tides” for the next few days, according to the National Weather Service.

Meteorologist Logan Johnson said king tides are a natural phenomenon that occurs when a special alignment of the sun, moon and earth creates a particularly strong gravitational pull.

He said that in the Bay Area, the higher tidal period starts today and is expected to last until Friday.

Johnson said the king tides could be especially noticeable in places like Marin County where there is a lot of development along local shorelines.

Water levels at high tide are expected to be a few inches to a foot higher than usual, and some flooding may occur, he said.

However, because of the dry weather so far this year, Johnson said water levels aren’t expected to be dangerous and no warnings or advisories have been issued.

Beach-goers are advised to stay away from the shore during high tide and be aware of higher water levels along low-lying roads and trails, on docks, harbors, park-and-ride lots and in other flat, developed areas.

The California King Tides Initiative, a partnership between state and federal agencies and nonprofits, is asking residents to take photos of the effects of the high tides and send them in, as long as the photos can be taken safely.

The photos will help researchers study sea level rise as part of a project of the National Oceanic and Atmospheric Administration’s National Estuarine Research Reserve System.

Photos can be submitted through the initiative’s website at

Another period of king tides is expected to occur between Jan. 29 and 31.
