The Admiralty Tidal Information Service

The Admiralty Tidal Information Service provides accurate and timely tide data, including predicted water levels and tidal currents, primarily for maritime navigation and coastal operations. Managed by the UK Hydrographic Office, it uses scientific observations and models to inform mariners, engineers, and planners about changing tides, ensuring safe and efficient navigation and coastal management. The service supports activities like shipping, fishing, and offshore construction by offering reliable information on tide timings and heights, helping users make informed decisions in relation to tidal conditions.
