Tide tables
You can download tide tables for Danish, Faroese and Greenland waters free of charge.
The tide tables give the heights of the tides at high and low water. This height must be added to the depth stated in a marine chart in order find the depth of water at high or low water.
Changes in heights of tides in the tide tables
In the tide tables for 2010 and 2011, changes have been made in the level (chart datum) that the tables refer to. This has been done so that the heights of the tides given in the tables correspond to the chart datum that is being introduced in new marine charts.
Denmark
Beginning with the tide tables for 2011, the heights of tides given for the west coast harbours refer to the lowest astronomical tides. (In the tables up to and including 2010, the heights of tides given for the west coast harbours refer to the mean low water spring.)
For the harbours within the Skaw, the tide water heights refer to the mean water level (unchanged).
The Faeroes
Beginning with the tide tables for 2010, the heights of tides given refer to the lowest astronomical tides. (In the tables up to and including 2009, the heights of tides refer to the mean low water spring).
Greenland
The heights of tides in the tide tables are unchanged, and refer to the lowest astronomical tide.

Height of water: measurements and forecasts
The tide tables are only an expression for the variations in the height of water which are the result of the gravitational force of the sun and moon (astronomic tides). The actual variations in the height of water are the total of the astronomic tides and the variations due to other factors such as wind and atmospheric pressure.
On this website, under “Sailing Forecast”, you can find measurements of water heights taken in Danish harbours by the Danish Coastal Authority, DMI and the Danish Maritime Safety Administration. You can also find forecasts of water levels for two days ahead. The forecasts include the tides and take into account the other factors that contribute to the variations in water levels.
