Annual Tide Tables for Walton-on-the-Naze, Margate, Southend-on-Sea, Coryton, Tilbury, North Woolwich and London Bridge can be found here on the Port of London website.
Our thanks to them for the service they offer to thousands of people using the waters of the Thames Estuary.

See below for tidal predictions to 2037 for regatta planning.

As you can see from the table below, Walton is 5 minutes earlier than Harwich.

Tide Tables up to 2037 for Regatta Planning

Magic Instinct Software have produced an add-on layer for Google Earth to read the data produced by the University of Udinese to give estimated tidal predictions world wide up to year 2037.

Download the little 220kB file from justmagic.com , page down to 'item 7 - Tide predictions for around the globe' and at the bottom of the section click on 'Open this Placemark' . Once the little file is downloaded, double left click on the file World-Tides.kmz to open it with Google Earth. This will load the add-on to 'Places' on your copy of Google Earth on your computer.

Navigate to the port you require, hover your mouse over a tide icon and you will see a popup box for tidal information. Click on the link and a tidal sine wave will load for todays date. At the bottom of the page is a date box for putting your day/month/year up to 2037

Thanks to Google; JustMagic; XTide; and the University of Udinese (Italy) for the data.


The data is offered WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  The author assumes no liability for damages arising from use of these predictions.  They are not certified to be correct, and they do not incorporate the effects of atmospheric pressure, storm surges, seismic events, continental drift, or changes in global sea level.
When atmospheric pressure is increased, sea level is lowered and vice versa. A variation of 1" Hg [approx 34millibars] in the height of the barometer causes a variation of about 12" [0.3m] in the height of sea level.
It is not unusual for storm surges to cause tides to vary by more than a metre from predictions in the Thames Estuary and times to vary by 20minutes or more. Such changes cause sea levels to oscillate between high and low level, gradually dying out as conditions become stable again.
