Tide tables state the time of high tide, the time of low tide and the vertical tidal range that day. This entry is from tables for a north Atlantic port with a large tidal range (the height figures are in meters) and semi-diurnal tides.ctually 24 hours 50 minutes. New York and London have classic semi-diurnal tides. The height of each high tide, and the fall of each low tide, is almost the same as the previous one, and the interval from high tide to high tide is about twelve hours 25 minutes.
