Tides

Warning

Tide tables are just a prediction of the action of the tide. Take it too literally and you may end up in trouble.  This is one unfortunate on the Medulse Rocks.

High tide time predictions are given in the Sailing Calendar, the club yearbook, and the table at the bottom of every web page, for high tides occurring while the boatman is on duty.

Many things can affect the predictions but the key ones for us at Granton are:

– The flow of the river – increase flow from upstream can push up the tide or impact the timings

– Atmospheric pressure – The effect of air pressure on tidal height is substantial and all too easy to forget.  Tide tables assume a standard pressure of 1013 millibars.  Roughly a change in pressure of one millibar will change the sea level by one centimetre.

Other predictions:

Here are a couple of the more useful tide predictions for us.  (They will open in a new window).  Don’t forget that these may need adjusting for BST (unlike the tables in the handbook).

Tide Plotter software is now available for Windows and Android. Its developers have been testing the Android version for some time at sea in a sailing environment. It does not require internet access after the initial installation and carries data for 2015 and 2016, for the UK and Ireland.

It is priced at £7.99 to cover royalty fees, Google’s commission and a little bit to put food on the table.

Some electronic chart packages have tidal information, including Navionics both on tablet and in chart plotters.
