[net.physics] tide periods

9212osd (05/08/83)

I have a table with the tides for a particular location.
I would like to extrapolate the data to figure out future
dates, for example.  Is there a formula(s) to compute tide
periods?  Or is 24:50 minutes accurate enough to extrapolate
to six months, for example?  Reply by mail, with
any formula, reference, or interesting information.  I will
post a summary if the responses are satisfactory.  No answers
to the net, please.
