Tides: Timetables

Volume 481: debated on Monday 20 October 2008

To ask the Secretary of State for Defence if he will arrange for the Hydrographic Office to issue tide times for 2009. (227632)

Tidal predictions are available from the United Kingdom Hydrographic Office (UKHO) in print, as software and online.

Admiralty EasyTide online service provides free tidal predictions for over 7,000 ports worldwide for the next seven days. Admiralty TotalTide software is accepted by the UK Maritime Coastguard Agency and other maritime administrations for use by SOLAS (Safety of Life at Sea) vessels, and can also be purchased for leisure and domestic use.

Official tide times, predictions and relevant data for 2009 are already available within Admiralty Tide Tables. They can be purchased online via the UKHO Admiralty webshop at:

via one of the Admiralty distributors listed at:

or viewed free of charge in a good reference library.

Official worldwide tide predictions are published no sooner than eight months in advance of a new year to ensure that they use the latest available information but in sufficient time for customers’ planning needs.

UKHO does, however, make the predictions available, e.g. through software or online services, years in advance. UKHO, however, cautions use of such predictions for safety critical work as predictions can change over time.

UKHO tide predictions are licensed to many organisations and individuals for a variety of public purposes and publications, the majority being free-of-charge licences.

Real-time tides are monitored at discrete locations by Proudman Oceanographic Laboratory through whom real-time tide gauge readings are available. Historical raw tide gauge data are obtainable from British Oceanographic Data Centre (BODC). Other agencies may also collect tidal data.
