(Accurate tide predictions can only be made if the 'harmonics data' for the relevant location is good. Unfortunately, the only way I have of knowing when the data is bad is when someone with access to authoritative tide predictions for the affected location tells me so. That is why you should not use this program or its data files if anyone or anything could come to harm as a result of an incorrect tide prediction. NOAA and similar agencies in other countries can provide you with certified tide predictions if that is what you need.) XTide's predictions do not incorporate the effects of tropical storms, El Niño, seismic events, continental drift, or changes in global sea level. ------------------------------------------------------------------------ The tide prediction algorithm used in this program was developed with United States Government funding, so no proprietary rights can be attached to it.
