The San Francisco Bay Area will experience exceptionally high tides and minor flooding along the bay’s shoreline on Saturday and Sunday mornings, the National Weather Service said. Extremely low tides will occur on Saturday and Sunday evening.

“Tide poolers and beachgoers should be familiar with the times and heights of local tidal levels to avoid hazards that may arise from rapidly shifting water levels,” the weather service warned.

David King, a forecaster with the weather service, warned that people at the beach can get into trouble by walking out to exposed tide pools during low tide and not returning to shore before the tide comes back in.

The astronomical tides, or king tides, usually occur in December and January, when the sun and moon reach their closest points to Earth, aligning the celestial bodies like a perfect cue shot to create maximum gravitation pull.

“We usually get two rounds of king tides in the winter time,” said King. “There’s usually one that happens in December. This is happening pretty much generally speaking when we expect.”

King Tides will impact the area the next 3 days & bring some of the highest & lowest tides of the year.

The high tides will be on Saturday at 10:30 am (7.13 feet) and Sunday at 11:16 am (7.11 feet), while low tides will occur Saturday at 5:23 pm (-1.7 feet) and Sunday at 6:13 pm (-1.76 feet). The level of the sea will shift some eight feet in a little over seven hours each day.

King tides are a preview of how sea level rise will affect coastal places in the future, the Environmental Protection Agency’s Climate Ready Estuaries program said.

“As time goes by, the water level reached now during a king tide will be the water level reached at high tide on an average day,” the program said.

The California King Tides Project is encouraging anyone near the coast to send in photos of the high tides, as part of its effort to increase understanding of what the state will experience as climate change causes sea level to rise.

SAN FRANCISCO (CBS SF) – BART officials said Wednesday climate change and sea level rise will pose a growing threat to the transit system in the coming decades.

The ailing transport company is trying to find money to combat the long-term but looming threat.

“One of the predictions is that by mid-century we might see tides a foot higher than they are now. So that’s 2050, ”said BART spokesman Jim Allison.

BART engineers say sea level rise could have a number of potential effects. For example, the Embarcadero train station in San Francisco could occasionally be inundated by floods.

Other stations could be threatened by rising groundwater, which would strain the existing pumps and the aging infrastructure of the system.

“The thing for me is that we’re at the height of technology and innovation in the Bay Area, but this is an old system that is really shabby,” said BART driver Jason Caballero.

BART has identified many of the potential problem areas, but the agency relies on injections of money from the federal government just to keep trains running.

“The devastating effects of the pandemic and the dramatic decrease in the number of passengers paying for their tickets have really turned our funding plan upside down,” Allison said.

BART drivers say they understand the transportation company’s financial plight but are concerned about the long-term costs of inaction.

“It might be better to say, ‘Let’s pretend it’ll happen in 10 years.’ And what could the BART system do in 10 years to avoid being caught wading in the BART system with pants down and knee-deep water? ”Asked rider Bianca Espinoza.

BART officials noted that several vulnerable stations are connected to other important pieces of infrastructure in the Bay Area, such as the airports in San Francisco and Oakland. Any plan to mitigate this impact would necessarily have to be regional and collaborative.
