How many tides are there in one day?

Question

I've heard people say 2 and some say 4, which one is true? And why?

Answer 1

Tides vary from day to day. As the earth, moon, and sun orbit , their position constantly shift, causing slightly different gravitational effects.  Some places have two tides in one day.

Answer 2

Depend where you are. Some places have 1 high and 1 low, some have 1 high high, 1 low high, 1 low low and 1 high low.

etc. Depends on the bathymetry of the area.

Answer 3

there are 2 full cycles. Each cycle has a high tide and a low tide. So there are 2 high tides and 2 low tides for a total of 4 tidal extremes.

Answer 4

Answer 5

2 high 2 low
