This section details the various formats in which the Tidal Prediction Service can provide data. The PDF formats and ASCII/data files can be sent by e-mail as a file/attachment or can be made available on an FTP site.

How to order and pay

Once you have chosen the formats, ports and years you require, you can order and pay for what you need via our ADMIRALTY Tidal Prediction Service website.

If you intend to reproduce the data in any way, you will need to apply online for a copyright licence. Depending on the purpose of the reproduction, there may be a licence fee. Once you have a copyright licence, we will send you a PayPal invoice for the cost of the predictions. We will send you the predictions once we have had confirmation of payment.
