Tide 

Here tides coming from some harmonics files find on internet. This information is provided without warrant. It requires confirmations on sites, already done in Somme, France and Mayotte, Indian Ocean . Do not hesitate to leave a comment.

Lunation has an influence on the amplitude of the tides. Between new moon (age 0) and full moon (age 14), the amplitude increases with a lag of a few days. The growth of the moon (ages 0 to 15) would also have an influence on the rise in sap of plants. The tidal wave moves counterclockwise in the northern hemisphere and clockwise in the southern hemisphere around amphidromic points. Example, the flow in the English Channel, just like in the Mozambique Channel, comes from the south.
