California King Tides Project

Our #KingTides project dates are almost a month away, but California is seeing record high tides already. If you plan to photograph the king tides, or are just thinking of heading to the coast during this El Niño, PLEASE BE SAFE. Here are some tips: www.coastal.ca.gov/kingtides/sa...

We talk a lot about how the #KingTides Project helps us visualize sea level rise so we can imagine what it will be like when the winter king tides are our every day high tides. This fall is really driving the point home.

New research finds that "coastal flooding events expected only once every 100 years are now, on average, about 12 times more likely to occur. Climate change has made those events about four times more likely since 1900." news.tulane.edu/pr/sea-level...

We have reached the point of the summer king tide season that the Santa Venetia Marsh berm is overtopping. We are about a month out from the highest summer tides. Remember that in the summer king tides happen at night!! @kingtides.bsky.social #KingTides #SanFranciscoEstuary #SFBay #SeaLevelRise

Our higher than average high tides have set a new record for sea level in (meteorological) Summer. A couple factors are unique to June 2026 and we’re likely to see more of this including dangerous surf at times through midweek. 6/14/2026 #BayArea #SanFrancisco #ocean #California #surf

The National Weather Service forecasts a tide 2 feet above the typical high tide in San Francisco on Sunday evening. That would be the highest summer tide on record by nearly 4 inches and among the 20 highest tides since 1897.

An advisory on Friday, June 12, warned a series of high tides, called king tides, are expected on Saturday, June 13, through Tuesday, June 16, in the evening hours.

King tides, dangerous surf prompt warnings along Southern California coast

From The Wedge to Crystal Cove, a historic Southern California swell strips away sand, exposes buried infrastructure, and sends a lifeguard tower into the sea.

Thank you to everyone who contributed #KingTides photos to the California King Tides Project. Your photos help us understand the impacts of sea level rise and the climate crisis. Today's king tides are tomorrow's every day high tides. See the photos at arcg.is/0Gy5Cq

California just experienced its warmest December since 1895, shattering the previous record by 1.3 degrees. That may surprise people in the bay and valley, but late-month warmth also offset the cold start there and a ring of records encircled the state. Read: www.sfchronicle.com/weather/arti...

Questions about the highly disruptive recent King Tides in Northern California in the context of sea level rise? How about the potential for a (significant) El Niño event to develop by spring or summer? Join me live on Wed, Jan 7 at 2pm PT to discuss!

China Beach was under water during #KingTides on Jan. 3

Yes it did. Saturday Jan. 3 #KingTides

🌧️Marin County Looked Like ‘a Lagoon’ After King Tides, Heavy Rain “We’re seeing stronger storms as we go forward, and the predictions are that we are going to continue to see more intensity in the storms and wilder swings,” @kqednews.kqed.org @kqedscience.bsky.social www.kqed.org/news/1206864...

Phew this was quite a #KingTides season. If you haven't uploaded your photos yet, you can do that here survey123.arcgis.com/share/046c76.... We're still catching up with your submissions, and you can see them as they're added to the map: arcg.is/0Gy5Cq. TY for creating this record of coastal change!

So delighted to join Friends of Sausal Creek and I (Heart) Oakland-Alameda Estuary for a fun and informative nature walk through Jingletown to the water's edge in Oakland. Well done, team and great time had by all - even in the rain! #oakland #kingtide #sausalcreek #sealevelrise #wildlife

Got some footage of the @kingtides.bsky.social overtopping the outer berm at Santa Venetia Marsh. There is a known population of @thesaltymouse.bsky.social here. Winter #KingTides are likely the deadliest time of the year for SMHM. Luckily the weather was pretty mild during these tides. 🌊🧂🐀🌊

Cruised over the the entrance to the Eastern span of the SF Bay Bridge for #KingTide today. Right up to the Bus Entrance Road, with just the cement barrier in between.
