In most places on earth how often do high and low tides occur

Every lunar day, areas near the sea undergoes two high and two low tides, which takes place every 24 hours and 50 minutes.

Explanation:

A Tides can be explained as the rise and fall of sea levels brought into play by the combined effects of the gravitational forces exerted by the Moon and the Sun, combined with the rotation of the Earth.

This causes a rise and fall of sea water. High tides takes place for about 12 hours and 25 minutes apart.

And It takes upto six hours and 12.5 minutes for the water close to the sea to go from high to low, or from low to high tides.
