↓ Falling The tide is falling. 1 h 19 min to low tide at 4:58 am.

In San Giovanni the astronomical tide is very small: about 0.8 ft between high and low tide. Here the sea level is moved mostly by wind and air pressure (storm surge), which can raise or lower it more than the tide itself.

2026 extremes: the highest tide of the year is on September 26 (1.0 ft) and the lowest, on February 3 (-0.4 ft).

Heights above MLWS. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLWS
