The tidal range is the vertical difference between the high tide and the succeeding low tide. Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth.
TIDAL COEFFICIENT COCODRIE. The tidal coefficient today is 46, a low value, which means that the range (difference between high tide and low tide) will be lower than on other occasions and the currents will also be small. At noon the tidal coefficient drops to 41. The day ends with a tidal coefficient of 38.
