Is there are formula for calculating the time of low and high tides and also their heights?


Yes, there are formulas. Software is available from the National Ocean Service of NOAA at

You can look at the "History of Tidal Analysis and Prediction" link in the boxes at the bottom of the page to see how the predictions developed.

Back on the home page, use the link at the bottom of the page, "Oceanographic Products and Services". Then use the link "Frequently Asked Questions". Then scroll down to "I want to develop my own program to predict the tides......" This describes what is needed to be able to make predictions. The prediction program is in the FORTRAN language (which I use all of the time and is fine for me), so it may not be convenient for you if you do not know that language.

An email address and phone number are provided so that you can call them and place an order or get more information.
