I know that an area has a diurnal tidal cycle if it experiences one high and one low tide every lunar day. Many areas in the Gulf of Mexico experience these types of tides. I read that:
Diurnal tides occur due to a series of factors, among which continental interference and the Earth's spin axis are the most important to be considered.
But I don't understand of Earth's tilt affect some ares like the the Gulf of Mexico and don't affect similar places like the Gulf of Oman or the Gulf of Aden
