Times and heights of high and low water at a named port.
Also known as: Tide times, Tidal prediction table
A tide table gives predicted times and heights of high and low water against chart datum for a standard port, with corrections for secondary ports. The figures are predictions from astronomy, and actual water can differ substantially under barometric pressure or wind.
