Tide Information

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 Club Hours, for high tides occurring while the boatman is on duty. These predictions are based on information from Belfield software. The times will differ slightly between all prediction systems. Links to various different prediction systems are given below, so you can check them for yourself.

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

  1. The flow of the river - increase flow from upstream can push up the tide or impact the timings
  2. 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.

Forth Ports Authority information

Forth Ports provide tide tables for Grangemouth, Rosyth, Leith, Burntisland, Methil, Dundee and River Tay bar, with all times in GMT.

Other predictions

Here are a couple of the more useful tide predictions for us: Don't forget that these may need adjusting for BST (unlike the tables in the handbook).

The National Tidal and Sea Level Facility (NTSLF) provide tidal heights for Leith as follows. Click on the image to see high and low water times on their website.
