how your tide clock work
The tidal cycle lasts an average of 12 hours, 25 minutes and 14 seconds between two high tides.
This duration is not exactly the same from one tide to the next: it can naturally vary depending on lunar cycles and local conditions.
Today: A variation of up to one hour compared with conventional tide tables may be observed. This phenomenon is temporary, so there is no need to readjust your tide clock.
