In the Adriatic, the high and low tides have relatively small amplitudes. In some narrow channels and bays, the high tide can grow considerably during a strong sirocco.
Waves and Currents
Waves occur primarily as the consequence of the blowing of winds. Heights of waves in the Adriatic are between 0.5 and 1.5 metres, and they very rarely exceed 5 metres. Currents are rare in the Adriatic.The speed of currents changes in particular areas, but it also depends on time periods. The average speed of currents is about 0.5 knots, but they can also reach the speed of 4 knots.
