This is the week I'm due to be in St Ives on holiday...

Last year I had a Tide Table booklet for Cornish ports issued free by a
local chandler. (MacSalvors, Pool)
Included in the notes inside the front cover was the information that the
Highest Astronomical Tide will occur at 0624 GMT on 2 March 2010 and the
Lowest Astronomical Tide will occur at 0039 GMT on 22 March 2015.

My tidal prediction problem

Program?

does seem to confirm this.

Is this program available on the web somewhere?

It's the original version of Tides. An updated version was released but
without the necessary data for the United Kingdom because the Hydrographic
Office reckoned they had the copyright to it.
My program works well and the predictions it produces are within 10-15
minutes of those of the Hydrographer.
It's no longer available on the web but I'd be happy to put a copy on my
website so that you could download it.

The penny has at last dropped!
Of course I meant program.
As I said before I blame the tablets!

But it was on the previous version?

It's the heights, rather than the times I'm most interested in.

It's no longer available on the web but I'd be happy to put a copy on my

That would be great.

BTW, will it run on any version of Windows?

All shown in graph form, along with sunrise/sunset and twilight times for
each port.

website so that you could download it.

That would be great.

It's a file called Tides.exe which needs to be downloaded, scanned for
nasties

Is that a particular problem with this program then?

and then run to install it on your computer.

It ran for me under Windows 98, Windows ME and Windows XP SP2.

OK, good.

Download it from http://sites.ecosse.net/mike.clouston/tides.exe but be
quick as I'll only leave it there for 48 hours - don't want to incur the
wrath of the Hydrographer!

Got it - thanks.

Not at all. It's an .exe file though and they should all be scanned after
downloading and before running. Try e-mailing an .exe file and you'll most
probably find that you'll have to re-name it before it will be accepted by
most ISPs.

It's a great program, although it doesn't cover St Ives specifically.
The nearest location is Falmouth.

I'm pleased you like the program, Paul.
For St. Ives subtract 15 minutes from Falmouth times - see
http://www.falmouthpacket.co.uk/weat...ipping/inport/

Times are easy, but as I mentioned, I'm more interested in heights.

Have a look at this page - http://www.neptune-navigation.com/tides.htm -
from where a 14-day trial of the program NeptuneTides can be downloaded. It
gives height and times for many more UK ports than Tides.exe

Thanks.

Here's a thread with useful links that I posted on another forum.
--------------------------------------------------------------------------------------------------------------------------

Thankfully, there will not be a storm sturge with these high tides in
September because High Pressure will be over the UK supressing the
height of the tide by a few Centimetres.

http://www.wetterzentrale.de/pics/avnpanel1.html

A rough guide is that a change in pressure of one millibar (one
hectopascal in modern units) will change the sea level by one
centimetre. Tide tables assume a standard pressure of 1013 millibars.
This means that a pressure of 1040 mb, pretty high but not abnormally
so, could give a sea level lower by nearly 30 cms than expected.

http://www.franksingleton.clara.net/...and_tides.html

For an approximate rule of thumb, subtract 1013 from the air pressure,
then subtract the result (in centimetres) from the tide height. For
calculations remember than 'minus minus' is actually 'plus', and 'minus
plus' is 'minus'.

Example #1: Pressure at 1005, minus 1013 equals -8. Subtract this from
a tide of 8.1m, 810cm - (-8cm) = 818cm (8.18m).

Example #2: Pressure at 1025, minus 1013 equals +12. Subtract this from
a tide of 8.3m, 830cm - (+12cm) = 818cm (8.18m).

http://www.wsyc.org.uk/wsyc_pages/ws..._pressure.aspx

---------------------------------------------------------------------------------------------------------

Use the Free Link below, for published tidal predictions in your area,
then adjust the height according to prevailing air pressure on the
forecast date.

http://easytide.ukho.gov.uk/EasyTide...electPort.aspx

These tides are indeed very high. For instance, Teignmouth is
predicted to have a High Tide of 5.3m on the evening of Fri 8th Sept,
the highest tide I can every remember being published for Teignmouth is
5.5m.

A 10 day trial, actually.
