(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.
