  2. Tide table - Wikipedia

    en.wikipedia.org/wiki/Tide_table

    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 ...

  3. Tide - Wikipedia

    en.wikipedia.org/wiki/Tide

    The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see Timing).

  4. Theory of tides - Wikipedia

    en.wikipedia.org/wiki/Theory_of_tides

    High and low tide in the Bay of Fundy. The theory of tides is the application of continuum mechanics to interpret and predict the tidal deformations of planetary and satellite bodies and their atmospheres and oceans (especially Earth's oceans) under the gravitational loading of another astronomical body or bodies (especially the Moon and Sun).

  5. Farmers' Almanac - Wikipedia

    en.wikipedia.org/wiki/Farmers'_Almanac

    Predictions cover 16 months, from the previous September (through December of the publication year). The Farmers' Almanac will only state publicly that their method is an "exclusive mathematical and astronomical formula, that relies on sunspot activity, tidal action, planetary position ( astrology ) and many other factors".

  6. Chart datum - Wikipedia

    en.wikipedia.org/wiki/Chart_datum

    A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).

  7. Tide clock - Wikipedia

    en.wikipedia.org/wiki/Tide_clock

    Tide range is the vertical distance between the highest high tide and lowest low tide. The size of the lunar tide compared to the solar tide (which comes once every 12 hours) is generally about 2 to 1, but the actual proportion along any particular shore depends on the location, orientation, and shape of the local bay or estuary.

  8. King tide - Wikipedia

    en.wikipedia.org/wiki/King_tide

    King tides are the highest tides. They are naturally occurring, predictable events. Tides are the movement of water across Earth's surface caused by the combined effects of the gravitational forces exerted by the Moon, Sun, and the rotation of Earth which manifest in the local rise and fall of sea levels.

  9. Standard port - Wikipedia

    en.wikipedia.org/wiki/Standard_port

    A Standard port is a port whose tidal predictions are directly given in the Tide tables. [1] Tide predictions for standard ports are based on continuous observation of tide over a period of at least one year. These predictions are given in feet or meters, with respect to the chart datum for average meteorological conditions. [2]
