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.

In Maine (U.S.), low tide occurs roughly at moonrise and high tide with a high Moon, corresponding to the simple gravity model of two tidal bulges; at most places however, the Moon and tides have a phase shift. Tide coming in, video stops about 1 + 1 ⁄ 2 hours before high tide Tide coming in
When the clock reaches the halfway point ("half-tide"), it then counts the hours up to high tide or low tide, as in "one hour until high or low tide". Generally, there is an adjustment knob on the back on the instrument which may be used to set the tide using official tide tables for a specific location at either high or low tide.
Diurnal and semidiurnal astronomical tides: 12–24 h P: 0.1–10+ m Long-period tides: 2-week to 1-year P <0.1 m Pole tides (Chandler wobble) 14-month P: 5 mm Meteorological and oceanographic fluctuations Atmospheric pressure: Hours to months: −0.7 to 1.3 m Winds (storm surges) 1–5 days: Up to 5 m Evaporation and precipitation (may also ...
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 ...
A king tide is an especially high spring tide, especially the perigean spring tides which occur three or four times a year. King tide is not a scientific term, nor is it used in a scientific context. The expression originated in Australia, New Zealand and other Pacific nations to
According to NOAA, Miami didn’t have high tide floods at all last year.
