All tidal, solar and lunar data values are predicted. Primary tidal information is supplied by and copyrighted to the South African National Hydrographer, SA Navy. The National Hydrographer is not responsible for any transcription errors. All secondary port tidal data as well as sunrise, sunset, moonrise and moonset data is derived by Ocean Rhythm.

Primary port tidal information is supplied by and copyrighted to the South African National Hydrographer, SA Navy. The National Hydrographer is not responsible for any transcription errors.

Primary ports are: Walvis Bay, Luderitz, Port Nolloth, Saldanha, Granger Bay, Simon's Town, Hermanus, Mossel Bay, Knysna (lagoon), Port Elizabeth, East London, Durban and Richard's Bay.
These ports have an official tide chart datum as desribed in the Chart Datum page - the link is on the Ocean Rhythm home page. Primary tide ports are high-lighted on the selection page.
Secondary ports do not have a chart datum (geographic height reference) and hence only tidal range data is provided.

Linking to tidal data on the Ocean Rythm page is possible via a preferred avenue which will shield your site from having to fix broken links as the Ocean Rhythm page evolves.
Since the tide data pathways may change without notice, any form of direct linking is strongly discouraged. Deep linking directly to tidal images is prohibited and considerd as an act of plagiary unless you have been provided with an access URL to this end by Ocean Rhythm. Please write to Ocean Rhythm (contact details below) stating what you would like to link to and you will be provided with an URL which your page can call safely.
