Types of tides worldwide

This product shows the international distribution of types of tides. Four types of tides exist, and are classified based on the number and height of high and low waters each day:

semi-diurnal tide: two high tides and two low tides with approximately the same height are recorded each day.

Mixed tides with diurnal inequality: two high and low tides are recorded daily (just like with semi-diurnal tides), however the heights of the high and low waters vary significantly over the same day. Diurnal tides: one single high tide and one single low tide are recorded each day.

Composite: tides can be diurnal or semi-diurnal or mixed.

Statement: The type of tide at a given location depends on the ratio between the total amplitudes for waves O1 and K1 and the total amplitudes of M2 and S2. These amplitudes are taken from the Shom tidal models and database.
