California King Tides Project: Photograph the Future January 1–3, 2022
King Tides are the highest tides of the year
King Tides are the highest tides of the year. These tides may surprise casual beach-goers (especially when the tides rise high enough to submerge the whole beach), but they occur each winter at predictable points in the earth’s journey around the sun.
King Tides occur under the following conditions
- Earth is at its closest to the sun (i.e. at perihelion),
- the moon is at its closest to the earth (i.e. at perigee), and
- all three bodies are aligned, producing either a full or new moon.
Because these tides occur when the moon is at perigee, the more technical name for them is perigean-spring tides. The infographic below, from NOAA Ocean Service, illustrates the conditions that combine to create these extra-high tides.
In this position, the sun exerts an extra gravitational pull that causes the ocean bulge to increase further. Watch the video below to see this process in action.

King Tides Show the Future of California’s Coast
Scientists need you to be their eyes on the coastline during this year’s King Tides. These extreme tides often encroach on infrastructure, submerging coastal access stairways, swallowing beach-side trails, overwhelming boardwalks, surging into storm-drains, and flooding roads. They can also inundate coastal habitats that aren’t typically submerged, like higher marsh areas or even dune scrub.
With the rate of sea level rise increasing worldwide, what we consider ultra-high tides today may be what we experience every day in 2050 or 2100.
California King Tides Project photos inform scientists and policy makers
The California King Tides Project depends on community members to head out to the coast during King Tide events, take photographs of infrastructure and wild lands when the tides are at their highest, and upload them to the King Tides Project’s database. These photographs are added to the project map for everyone to see, and the data they contain helps researchers and policy makers evaluate potential impacts to California’s coastline as the sea level continues to rise.
This issue will become more important as time goes on. A recent NPR Science article reported that an estimated 10 billion dollars worth of property in California is likely be consistently underwater by 2050. According to NPR, the additional property that falls below the water line at high tide may bring that value up to 16 or even 20 billion dollars.

Participate in the California King Tides Project
Step 1: take pictures at high tide
It is easy to participate. Just pick one of the days below, find a safe place to view the tides, and snap a picture during the morning high tide. The tide table below is adjusted for Morro Bay from the NOAA Tides and Currents predictions for Port San Luis. This year’s King Tides are predicted to be higher than the past two years—the high on January 2 will likely top seven feet!
|Date||High Tide||Height||Low Tide||Height|
|January 1||8:10 AM||6.93 ft||3:43 PM||-1.74 ft|
|January 2||8:58 AM||7.04 ft||4:30 PM||-1.93 ft|
|January 3||9:47 AM||6.95 ft||5:18 PM||-1.88 ft|
The extreme high tides are mirrored by extreme low tides during these times. If you’d like to see the contrast between the two, try visiting the same spot at high and low tides on the same day. You’ll be amazed at the difference. We’ve listed both the high and low tides in the table, though the King Tides Project collects photographs only of the high tide impacts.
This image shows the stairway to the beach at Tidelands Park. An ultra-low tide is pictured on the left and an ultra-high tide on the right.
COVID and coastal safety precautions
If you choose to contribute to the California King Tides project this year, please comply with COVID safety precautions when you do so. This means taking photographs while you are already out and about for exercise rather than making a special trip. It is also important to wear a mask over your nose and mouth and to keep at least six feet of distance from others.
There are also typical coastal safety concerns to keep in mind. Please exercise caution near the bay and open ocean. Keep your eye on the waterline, avoid jetties and big waves, and keep your distance from bluff edges and overhangs. Your safety is much more important than any photograph.
Step 2: upload your pictures
This is the most important part! Please take the time to download the free Survey123 app and upload your photographs to the California King Tides Project.
Click here to visit the California King Tides Project’s website for detailed instructions on downloading the app and using it when you have phone service or when you’re out of the service area.
Share your photographs on social media
Once you have uploaded your pictures to the California King Tides Project website, you can also share them on social media to bring more attention to the cause! Please tag us @morrobaynep and the California King Tides Project @ca_king_tides. Use #kingtides
Help protect and restore the Morro Bay estuary
- Donate to the Estuary Program today and support our work in the field, the lab, and beyond.
The Estuary Program is a 501(c)3 nonprofit. We depend on funding from grants and generous donors to continue our work.
- Support us by purchasing estuary-themed gear from ESTERO. This locally owned and operated company donates 20% of proceeds from its Estuary clothing line and 100% of Estuary decal proceeds to the Estuary Program. Thank you, ESTERO!
- Purchase items from the the Estuary Program’s store on Zazzle. Zazzle prints and ships your items, and the Estuary Program receives 10% of the proceeds. Choose from mugs, hats, t-shirts, and even fanny packs (they’re back!) with our fun Estuary Octopus design, our classic Estuary Program logo, or our Mutts for the Bay logo.
Thank you for your support!
