The data is produced by the program WXTide32 - available from
The Unix version,
XTide is used as the 'engine' for a number of web based tidal predictors. In November 2003 the British Oceanographic
Data Centre (BODC) based at the Proudman Oceanographic Laboratory in Liverpool granted the creator of XTide
permission to use its tidal height data to derive its own harmonic constants. Consequently, predictions from WXTide32
will differ from those produced officially for the BODC. The main determinant of differences from predictions
remains local weather conditions.
