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 2017, beach erosion worsened with high-energy king tides and elevated sea levels. Honolulu's mayor stated: "I'm not a scientist, but I'll get a jackhammer in there and remove all the concrete that's there creating this backwash and sucking out more sand, plus it's just downright dangerous."

Mean high water springs (MHWS) – The average of the two high tides on the days of spring tides. Mean high water neaps (MHWN) – The average of the two high tides on the days of neap tides. Mean sea level (MSL) – This is the average sea level. The MSL is constant for any location over a long period.
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 tide that brings unusually high water levels and can cause local tidal flooding. Some images taken around #GigHarbor at approximately 9:00 a.m. on 12/27/22 (high ...
A magnitude 5.7 earthquake struck the world’s largest active volcano on Friday — Mauna Loa on the Big Island of Hawaii — knocking items off shelves and cutting power in a nearby town but not ...
North Shore is known for its extreme high surf in the winter season, starting around early November and possibly lasting to as long as June or July. [8] Waves around this time are around 16 feet on average as measured from top to bottom of the waves' "face" -- the side of the wave that faces the shore.
