We now have our winter 2026/27 #KingTides Project dates posted on our website, and our map of tide times and heights is updated. Check it out at www.coastal.ca.gov/kingtides/

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

According to NWS, San Francisco just recorded the highest Summer water level on record. #KingTides

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...

The heat energy we added to the ocean LAST YEAR is the equivalent of: - Detonating ten hydrogen bombs every minute - operating over a hundred large power plants continuously for all of written human history - Five times all the electricity human beings have ever used

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. 🌊🧂🐀🌊

Two days of impressive King Tides

A king tide coupled with heavy rain over the last 2 days has caused flooding throughout Marin county. Which seemed like a good reason as any to ride China Camp, which borders the bay.

today's King Tide at the Port of Redwood City The crisp image is marred by the strong stench of raw sewage.

Had to spend a lot of time outside today to try to cope… #KingTide on the Petaluma River did not disappoint. This was about 1 hour before the highest tide; river is as high as I’ve seen it.

Border of Redwood Shores and Foster City ( Belmont Slough) Sat, 1/3 at noon #King Tides

We’ve had extreme king tides Friday & Saturday. Both broke records, Friday’s was about 10.1 ft and Saturday’s was 10.37. The wind pushed a small amt on our backyard, both pic #1 & 2 are our neighbor’s backyard. When the tide went out , the H2O went out as well. #humboldtcountyca
