Sereno Del Mar has no station of its own, so we use the tide at Bodega Harbor Entrance (NOAA), 5.3 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger. It is a NOAA subordinate station: its times and heights come from the San Francisco (Golden Gate) reference station with the official corrections.
