Tidal Prediction Service

The Tidal Prediction Service (TPS) offers customers bespoke tidal predictions in a range of different layouts, in either digital or analogue formats, for the appropriate administrative charge.

Tidal predictions can be provided for Standard and Secondary Ports. The charges depend upon the file layout received and whether the format is digital or analogue, and are applied on a per-port-per-calendar-year basis.

If you intend to reproduce the data in any way you must complete an online copyright application, which is available at http://copyright.ukho.gov.uk. All information you require regarding copyright and contact details can be found on this page.

NB: You must purchase an original copy of the predictions to apply for copyright.
