Fig. 1: Types of tides
Tide changes proceed via the following stages:
- Sea level rises over several hours, covering the intertidal zone; flood tide.
- The water rises to its highest level, reaching high tide.
- Sea level falls over several hours, revealing the intertidal zone; ebb tide.
- The water stops falling, reaching low tide.

What is the Contrast between a spring tides and neap tides?
Perigee tides involve the Moon's orbit around the Earth. It does not go in a perfect circle but rather in an ellipse/oval shaped revolution. Because of that there are some points in the Moon's orbit at which the Moon is closer to the Earth. "Perigee" is the point of closest approach. With that closeness it causes a greater gravitational attraction between Earth and the Moon, pulling more water towards the Moon, causing what we know as high and low tides. "Spring tides" can occur during a perigee tide but not necessarily. A spring tide is a tide that occurs when the Sun, Earth and the Moon are nearly in a straight line, at a NEW MOON, or at a Full Moon. The highest tides happen then.
How long does it take to go from one high tide to the next high tide?
On average, high tides are separated by about 12 hours and 24 minutes. The 12 hours is because of earth's rotation, and the 24 minutes is compensation for the movement of the moon. So low tides would be about half way through those 12 hour 24 minute periods.
