TotalTide - UKHO's award winning tidal program

What is TotalTide?

TotalTide is produced by the UK Hydrographic Office to provide instant tidal height and stream predictions worldwide.

TotalTide uses official data from the world's premier hydrographic authorities to calculate highly accurate positions.


Tidal heights for the world's Standard and Secondary Ports are displayed clearly and concisely in both graphical and tabular format. It uses the same prediction algorithms and Harmonic Constants as the Admiralty Tide Tables. Tidal Stream rates, for more than 3000 positions worldwide, are presented on a chart-based diagram.



TotalTide enables you to select and simultaneously calculate tidal heights for multiple ports for up to seven consecutive days. Results include periods of daylight and nautical twilight, moon phases and a springs and neaps indicator. Under keel and overhead clearance can be calculated and displayed as a simple, yet comprehensive graphic to ensure safe passage making and port entry. You can also utilise the prediction algorithms by inputting privately held harmonic constants if desired.
