Tide clock and tide predictor

XTide provides tide and current predictions in a variety of formats. It can generate graphs, text listings, and calendars, or put a tide clock on your desktop. Xtide works through three separate programs: the X Windows interface (xtide), the non-interactive or command line interface (tide), and the web interface (xttpd). XTide uses the same algorithm to predict tides as the National Ocean Service in the U.S. It is much more accurate than a simple tide clock from a novelty store. However, to predict tides accurately you also need special data for every location for which you want to predict tides. XTide reads this data from harmonics files that you must get from Bob Kenney's web site, http://flaterco.com/xtide/files.html. XTide's predictions are only as good as the available harmonics data. Due to issues of data availability and of compatibility with non-U.S. tide systems, predictions for U.S. locations tend to be much better than for locations outside of the U.S.
