Detailed explanation-1: -On an average, every place experiences high and low tide a day at an time interval of 12 hours 25 minutes. Since the earth completes its rotation in roughly 24 hours, every place should experience tide after 12 hours but this never happens.
Detailed explanation-2: -Earth rotates through two tidal ‘bulges’ every lunar day. Coastal areas experience two high and two low tides every 24 hours and 50 minutes. It takes around 12 hours and 26 minutes between two successive high tides, or two successive low tides.
Detailed explanation-3: -Coastal areas experience two high and two low tides every 24 hours and 50 minutes because the Earth rotates through two tidal “bulges” every lunar day. High tides occur every 12 hours and 25 minutes.
