The answer is The coastline experiences tidal bulge twice a day. This occurs due to the rotation of the earth. When the sun is either on the same side as the moon or opposite side of the moon relative to the earth (which happens twice a day), then the coastline will experience high tide on these two occasions. Tides are caused by gravitational effect on water masses on the earth that cause them to bulge towards the direction of the two celestial bodies.
