About the tides at Upper drawbridge

Tides here are mixed. On average the two daily highs differ by 1.1 ft, so check which low is the lower one before you head out. The pattern follows the reference station at SAN FRANCISCO (Golden Gate). The range is large, about 5.2 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 6.7 ft. The next spring tides peak today, with a range of 7.5 ft. Neap tides follow tomorrow, when the range shrinks to 4.6 ft.

Upper drawbridge is a subordinate station. NOAA predicts its tides by adjusting SAN FRANCISCO (Golden Gate): highs come about 131 min and lows about 179 min later than there. NOAA measured the tide here from 1977 to 2014 to set up these predictions. The nearest other station is Hog Island, 6 mi away, where high tide comes about 24 min earlier. For tidal currents, see Petaluma River entrance.

Predictions are based on SAN FRANCISCO (Golden Gate).
