Tides are more complex than people think. Tides are like the "modes" of a standing wave which is driven by two main forcing mechanisms - the moon's relative orbit (twelve and a bit hours) and the earth's spin relative to the sun (twenty four hours). Those are the "fundamental" frequencies but there are harmonics on top of those. The lunar tides are referred to as M0, M1, etc. M0 is the biggie that we're all aware of. M1 and so on take a bit more effort to detect but they're all there if you look hard enough. Then you take all that mathematical soup and force it to interact with uneven bathymetry (sea bed shape) and it all gets very weird. But utterly predictable.

In the course of a day, the moon earth and sun are in line or at angles so that 2 high tides and 2 low tides a day.

Occasionally there are 3 tides in a day, but never more.

You are probably thinking of currents there are always two tides - high and low. However there are many currents.

ANY 1 PLACE ON THE WORLD U WILL HAVE MULTIPLE DIFFERENT FORCES ACTING ON THE WATER THEN YOU HAVE TO TAKE WATER DEPTH, TEMPERATURE UNDERWATER ACTIVITY, WIND SPEEDS WELL U GET THE POINT! TO SCIENTIFICALLY TESTS IT WE HAVE TO CREATE IDENTICAL EXPERIMENTS SIMULTANEOUSLY. OH YEAH THEN YOU ALSO HAVE HIGH TIDE IN ONE PLACE & VISA-VERSA

you are mistaken somewhere about the concept of tide.
