About the tides at Grant Line Canal (drawbridge)

Grant Line Canal (drawbridge) has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. The pattern follows the reference station at Port Chicago, Suisun Bay. The average range is about 2.7 ft. Spring tides add a little more at both ends. That is smaller than most California stations on this site. The next spring tides peak on October 28, with a range of 4.5 ft. Neap tides follow tomorrow, when the range shrinks to 2.5 ft. In the next 12 months the highest predicted tide here is 4.7 ft on July 4, and the lowest is −0.4 ft on January 23.

Grant Line Canal (drawbridge) is a subordinate station. NOAA predicts its tides by adjusting Port Chicago, Suisun Bay: highs come about 374 min and lows about 380 min later than there. NOAA measured the tide here in 1979 to set up these predictions. The nearest other station is Borden Highway Bridge, 5 mi away, where high tide comes about 1 h 24 m earlier. For tidal currents, see Vulcan Island, 0.5 mile east of.

Predictions are based on Port Chicago, Suisun Bay.
