Predicted vs Actual Water Level
NOAA Point Reyes gauge · last 2448 hours
Tide predictions cover only the pull of the moon and sun. NOAA's Point Reyes gauge, about 24 miles away, measures the real water level every 6 minutes, so the gap between the two lines is the weather: storm surge, wind, air pressure and runoff. The same gap usually holds across the Marin coast and Tomales Bay.

Muir Beach Tides: What the Water Does in the Cove
Muir Beach tides mostly change how much beach you have to walk on. The cove sits halfway between Stinson Beach and the Marin Headlands, with dunes and a lagoon behind the sand. At low tide the beach is wider. At high tide the water pushes up the slope toward the dunes.
Redwood Creek and Big Lagoon
Redwood Creek drains 8.9 square miles off the slopes of Mount Tamalpais and comes out at Muir Beach. The beach’s old name was Big Lagoon Beach. A sandbar builds across the creek mouth, and winter floods break through it. That opening starts the coho salmon run in from the ocean.
Redwood Creek is the southern edge of the coho’s range. Adults run about 3 miles upstream to spawn in Muir Woods and the creeks around it. Steelhead trout use the creek too. The National Park Service restored the lower creek and lagoon in stages starting in 2009, adding a 0.4-acre tidal lagoon and a new creek channel for salmon and steelhead. You can read about the work on the Lower Redwood Creek page.
Surf and Safety
Only Stinson Beach is a swimming beach in this park. Muir Beach gets rip currents, cold water and sneaker waves, large waves that run up the sand without warning and can roll logs. Keep kids close and keep an eye on the water at any tide.
Tides for Muir Beach are predicted from NOAA’s Point Bonita (Bonita Cove) station, about 4 miles southeast near the Golden Gate.

About Tides at Muir Beach
How the tide works at Muir Beach
Muir Beach gets mixed semidiurnal tides, the usual pattern on the California coast: two highs and two lows most days, with one high noticeably higher than the other and one low noticeably lower. The lower low is the one that uncovers the most shore.
A typical day here swings about 6.2 ft from low water to the next high. The biggest spring tides of the next month stretch that to about 9.0 ft, and the quietest neap days shrink it to about 3.4 ft. The next spring tides peak around Nov 9.
Where the Muir Beach predictions come from
Every time and height is a NOAA prediction for NOAA's Point Bonita, Bonita Cove tide station (9414906), about 3.9 miles away. It is a subordinate station: NOAA predicts its highs and lows by applying time and height offsets to the San Francisco (Golden Gate) reference station.
The curve between each high and low is drawn with the standard cosine method, so heights between the turns are close estimates. Weather can move the real water level: strong onshore wind and low air pressure raise it, and offshore wind and high pressure lower it. Read more on how tide predictions work.
Reading the tide clock, table and chart
The tide clock's hand sweeps from high tide at the top to low tide at the bottom and back, one full turn per tidal cycle of about 12 hours and 25 minutes. The countdowns on either side show the time to the next high and the next low.
The day picker and the 7-day table list each turn of the tide with its time and height. On the chart, each crest is a high and each trough a low; shaded bands are night. Heights are feet above mean lower low water, so a negative number is a minus tide. Our guide on how to read a tide chart goes further.
Muir Beach Tide Questions
Are there tide pools at Muir Beach?
Muir Beach is mostly sand, and the park does not list it as a tidepool spot. For good tidepools nearby, the National Park Service points to Duxbury Reef at Agate Beach in Bolinas, up Highway 1 past Stinson Beach. Go there on a minus tide and arrive an hour before low water.
Can you swim at Muir Beach?
The National Park Service does not set Muir Beach aside for swimming. In Golden Gate National Recreation Area, only Stinson Beach is a swimming beach with lifeguards. The park warns that sneaker waves, rip currents and cold water make its other beaches unsafe to swim, at high tide or low.
Are dogs allowed at Muir Beach?
Yes, on the beach itself. Dogs can be on leash or under voice control on the sand. They must be leashed on Kaashi Way and the Coastal Trail, and they are not allowed in the Redwood Creek lagoon or the creek area behind the beach.
What time is high tide at Muir Beach today?
The panel at the top lists today's highs and lows at Muir Beach with their times and heights, and the tide clock counts down to the next high and the next low. Times are Pacific time and heights are in feet above mean lower low water (MLLW).
How big is the tide at Muir Beach?
Over the next 30 days the daily swing at Muir Beach runs from about 3.4 ft on the quietest neap days to 9.0 ft on the biggest spring tides, with 6.2 ft on a typical day. Like the rest of the California coast, most days bring two highs and two lows of unequal size.
Where do the Muir Beach tide times come from?
They are astronomical predictions from NOAA's Point Bonita, Bonita Cove tide station (9414906), about 3.9 miles away. Wind, storms, river runoff and air pressure can push the real water level higher or lower than predicted, so treat them as a planning guide, not a guarantee, and never use them for navigation.
