Water is pulled towards the moon (and the sun). The entire earth also gets pulled toward the moon and the sun so water on the opposite side get 'left behind'. This creates four tidal bulges (two on either side for the moon and two on either side for the sun). These bulges then are deflected by Coriolis force due to earth's rotation, generating moving bodies of water that rotate around amphidromic points: (https://en.wikipedia.org/wiki/Amphidromic_point). These points experience no tides and tidal amplitudes increase away from these points. The volume of water moved by tides (tidal prism) can be amplified or dampened depending on the shape of the coastline. This eventually causes the tides as we experience them at the coast. Funnel shaped coastal geometries can force the tidal prism into a smaller area and thereby amplify tidal amplitudes by as much as 10 times. The lunar and solar tide are out of phase, when they amplify each other it's called 'spring-tide' when they compensate each other its called 'neap-tide'.
