About the tides at Napa
Napa 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 San Francisco, San Francisco Bay. The range is large, about 5.4 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 6.9 ft. The next spring tides peak today, with a range of 7.5 ft. Neap tides follow on Thursday, when the range shrinks to 3.6 ft. In the next 12 months the highest predicted tide here is 8.8 ft on December 24, and the lowest is −1.6 ft on December 24.
Napa is a subordinate station. NOAA predicts its tides by adjusting San Francisco, San Francisco Bay: highs come about 125 min and lows about 157 min later than there. NOAA measured the tide here from 1978 to 1979 to set up these predictions. The nearest other station is Brazos Drawbridge, 6 mi away.
Predictions are based on San Francisco, San Francisco Bay.
