Hi,

How many hours would subj. be in Greenwich..?? Can't seem to find it
anywhere - must be searching for something wrong I guess.

Cheers

Have you tried searching for tide tables?

Does this link help?

Steen ,

Lunitidal Interval is the delay caused by water flow and restrictions that
occur to tidal waters.... ok so you already knew that I bet!

the trick is, I do not read it so much as measure it!

firstly the theoretical 'high water' occurs when the moon is at its zenith
(the time it reaches its highest point during any day.) find this out from
reference almanacs....for a given day and location. lets say it was 08:00

next, by observation at that point or by looking at tables find out what
time high tide does or is due to occur. let us say 10:30

the lunitidal interval is :- the observed time (10:30) minus the theoretical
time (08:00) = +2.5 hours

Bingo! lunitidal interval is 2.5 hours in our example....

I hope this is helpful... I have to program my tidal watch whenever I am
paddling away, and the above is how I do it. works for me !

Regards

Steve Frost

Of course you can observe it, but then the watch looses it's value,
doesn't it..?? I mean, that's what we 'always' do: learn the tide
table near by, observe the local facts, calculate for the next
high/low - adding 6.25 or 12.5 depending on the area.

Looking at the tidal hours around The British Isles, I would expect
that to be necessary too. I was surprised by the time difference.
