↓ Falling The tide is falling. 5 h 54 min to low tide at 10:13 am.
Tide coefficient 86 for the 3:47 am high tide and 80 for the 4:23 pm high tide. Average coefficient. The water rises and falls 15.4 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
Heights above mean sea level. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation.

Castro has no tide station nearby: its tide is calculated with the global FES2022 model, from the nearest model cells offshore (the first one 6.8 mi away). It may differ from the real tide by a few minutes and inches, and more with wind or storms. Heights are above mean sea level, not chart datum, so low tides are negative. Not for navigation.
