SAN FRANCISCO (KRON) — King Tides are returning to the Bay Area this week and into next, according to a tweet from the National Weather Service. This week’s King Tides are expected to bring some of the highest and lowest tides of the year.

“After the rain tonight, we have a prolonged period of sunny weather but if you live at the coast unfortunately, we still have one more hazard to keep an eye on. Beginning Thursday morning, our King Tides will bring higher than average tides that can lead to minor coastal and North Bay valley flooding,” said KRON4 Meteorologist Kyla Grogan.

The King Tides will begin Thursday and last through the weekend into Monday, the NWS said. The tides are expected to bring localized flooding to several low-lying areas along the coast and the SF Bay shore during high tides.

“Our first high tide Thursday morning happens in San Francisco at 8:28AM and these higher-than-average tides will continue through the weekend and into our Monday,” Grogan said. “So if you have plans to be at or near the coast this weekend, make sure you’re staying aware as some beaches and coves that are normally accessible may be closed off.”

Impacts of the King Tides are expected to be felt along the immediate coasts, Bay front, and coastal marshes and sloughs.

Impacts from King Tides could include:

  • Sea water on low-lying areas such as roadways, underpasses, coastal trails, and sidewalks
  • People visiting beaches may lose entry and exit to coves and narrow beaches
  • Mariners may experience issues with shallow water at low tides

“In addition to the high tides, anyone boating around the Bay this weekend should be aware of lower-than-normal low tides that are capable of causing issues for boats trying to enter and leave docking areas,” Grogan said. “The best bet is to avoid the coast if you can and wait for these King Tides to pass.”

The Southern Marin Fire District warned that a Coastal Flood Advisory is in effect from Jan. 19 at 6 a.m. through Jan. 23 at 3 p.m. The District advises to move vehicles to higher ground, move items stored in low-lying areas and to avoid driving through flooded roads.
