About the tides at Seaplane Harbor

Tides here are mixed. On average the two daily highs differ by 1.0 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. The range is large, about 5.3 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. The next spring tides peak on October 28, with a range of 9.2 ft. Neap tides follow tomorrow, when the range shrinks to 2.6 ft. In the next 12 months the highest predicted tide here is 8.6 ft on December 24, and the lowest is −1.8 ft on December 24.

Seaplane Harbor is a subordinate station. NOAA predicts its tides by adjusting San Francisco, San Francisco Bay: highs come about 42 min and lows about 63 min later than there. The nearest other station is Point San Bruno, 1.0 mi away. For tidal currents, see Point San Bruno, 0.51 nmi. east of.

Predictions are based on San Francisco, San Francisco Bay.
