Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
The clock of 1667 at Fécamp Abbey shows the time of local high tide, and the present state of the sea by means of a disc with a quarter-circle aperture which rotates with the lunar phase, revealing a green background at the syzygies (at new moon and full moon), when the tidal range is most extreme ("spring tides"), and a black background at ...
Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.

Ian's blowout tide pulled a large amount of water out of Tampa Bay, [81] with tides reaching 5 to 7 ft (1.5 to 2.1 m) below normal at the Hillsborough County side of the bay. Parts of the county also received 5 to 8 in (130 to 200 mm) of precipitation and wind gusts generally ranging from 65 to 75 mph (105 to 121 km/h).

In many parts of the world the tides approximate to a semi-diurnal sine curve, that is there are two high- and two low- tides per day. As an estimate then each period equates to 1 hour, with the tide rising by 1, 2, 3, 3, 2, finally 1 twelfths of its total range in each hour, from low tide to high tide in about 6 hours, then the tide is ...
