- Tide table
A tide table, sometimes called a tide chart, is used for tidal prediction and shows the daily times and height of
high water andlow water for a particular location. Tide heights at intermediate times (between high and low water) can be approximately calculated using therule of twelfths or more accurately by using a published tidal curve for the port.Tide tables are published as small booklets in their own right, as part of
nautical almanac s, on theInternet , in somenewspaper s (generally those serving readers in coastal regions or having maritime interests) and as the output of tidal predictionsoftware .Often tide tables are only calculated and published for major commercial
port s calledstandard port s. The tides for other minor ports can be calculated simply using a system of time and height "differences" between the Standard port and the nearby minor ports.The dates of
spring tide s andneap tide s, which have an interval of seven days, can be determined by the range of the height of the tide on the tide table; a small range indicates neaps and large indicates springs.On the
Atlantic coast of northwestEurope , the interval between low and high water is usually a little over 6 hours, giving one or two high waters each day and one or two low waters each day.External links
