About the tides at Dumbarton Highway Bridge

Dumbarton Highway Bridge has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. The range is large, about 6.7 ft on average. Flats and bars appear and vanish quickly, so keep an eye on the time. 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. The next spring tides peak tomorrow, with a range of 8.8 ft. Neap tides follow on October 17, when the range shrinks to 3.2 ft. In the next 12 months the highest predicted tide here is 10.1 ft on December 24, and the lowest is −1.8 ft on June 6.

This is a prediction station. NOAA calculates its tides from past measurements at this spot, but there is no live gauge today. NOAA measured the tide here from 1974 to 2011 to set up these predictions. The nearest other station is Newark Slough, 2 mi away, where high tide comes about 10 min later. For tidal currents, see Dumbarton Highway Bridge.
