Which tables provide daily predictions of height of water?

• A. Current Tables
• B. Depth Tables
• C. Tide Tables
• D. Forecast Tables

Answer: (C)

Tide prediction and water height are what this is about. Tide tables give the daily forecast of how high the water will be and when it will be high or low at a specific location. They are built from astronomical data and show, for each day, the times of high and low tides along with the corresponding water heights, usually in feet or meters above a chart datum. This daily height information is essential for planning entrances, landings, moorings, and safe clearance under bridges. Depth tables relate to the actual depths at a charted moment or after applying corrections; they don’t provide a daily tide cycle. Current tables show the speed and direction of water movement rather than height. Forecast tables cover general predictions like weather or sea state, not the specific tidal height schedule. Because tide tables are the source that directly forecasts how water height changes over the day, they are the right choice.
