Harmonic tides predictor for Ostend

A table of high and low harmonic tides and harmonic elevation time series for dates ranging from 1 January 1980 to 31 December 2020 can be obtained by filling out and submitting the following form. The start date is always required; the end date is optional. For clarity, sea surface elevation graphs are only displayed when start and end time differ by no more than 31 days.

— IMPORTANT INFORMATION ABOUT THESE PREDICTIONS —
Start date: Use format YYYY-MM-DD
Example: 20 May 1995 is 1995-05-20
End date: Use format YYYY-MM-DD
Example: 20 May 1995 is 1995-05-20

These computations are obtained using the harmonic constants method. In this method, sea surface elevation in one particular point is computed as the sum of a series of periodic functions, of which the period, amplitude and phase are deducted from the analysis of long term in situ observations at this particular point. Meteorological effects and the potential impact of global warming on the seal level are ot taken into account.

These results are made available only for information and without any warranty, even without the implied warranty of fitness for a particular purpose. They do not replace the official tide tables which for the Belgian harbours are published on a yearly basis by the Administratie Waterwegen en Zeewezen.

5–day forecasts in which meteorological effects are taken into account are available on this web site.
