Indeed, the tides measure in cm and the waves go about 1 or 2 meters farther on the sand, but the Med is treacherous. When the North wind is/has been blowing even lightly (at least on this side of the Med) the sea is dark blue, colder and there's only a light swell. It looks really safe but the currents draw you to the open sea. We heard of people drowning, we heard of people the costguards had to rescue be they bad or good swimmers or people on air beds who couldn't go back, but we never heard of anyone the currents brought safely to Algeria...
