About the tides at Mowry Slough
Tides here are mixed. On average the two daily highs differ by 0.9 ft, so check which low is the lower one before you head out. The pattern follows the reference station at San Francisco, San Francisco Bay. With a mean range of about 6.9 ft, the shoreline here changes a lot between high and low water. That is larger than most California stations on this site. From the average lower low to the average higher high, the difference is 8.6 ft. Over the next two weeks the biggest daily range, 10.4 ft, comes on October 28, and the smallest, 5.0 ft, on October 31. Looking a year ahead, predictions peak at 9.8 ft on December 24 and bottom out at −1.8 ft on December 24.
Tides here are worked out from the reference station at San Francisco, San Francisco Bay, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. NOAA measured the tide here from 1976 to 1985 to set up these predictions. The nearest other station is Coyote Creek, 2 mi away. For tidal currents, see Dumbarton Point, 2.25 miles SE of.
Predictions are based on San Francisco, San Francisco Bay.
