Find the Holes on the Beach
Finding the deeper water, the pockets that hold fish, is the key to finding fish along a beach. Some beaches are flat with just slight depressions; while others have distinct holes with severe drop-offs. In clear water and bright sun, look for the blue-green holes contrasting with the sandbars. In low light or when the water is discolored, you need to look at the shoreline and watch wave action for clues. Along some beaches, sand walls form in front of the bigger holes. They can be three to four feet high. A bowl between two points usually is a deep pocket of water, if the beach's slope is steep.
Watching wave action and how the white water moves over the beach's contour is the best way to find good water. Along flat sections of beach, which are devoid of holding water, waves break then roll all the way to the shore. In sections with sandbars and holes, the wave breaks over the bar, rolls for a distance, then disappears. Where this wall of white water disappears is the inside edge of the hole. Watch surface bubbles to determine the flow's direction. This flow moves from the corner back to the deeper water in the hole's middle, or in the case of a very large hole creates a long section of moving, fishable water. Without wave action look for a current line indicating a sandbar with a drop-off on the backside.
