Whitley pipe can be a good spot to spin for mackerel and puddlers.
With bait, I usually fish it as a low water summer mark. It fishes OK through the day, walk to the end and cast at about 45 degrees to the pipe, so aiming north east to put your bait on the rough ground. You’ll get coddling and puddlers and have a better chance if you use peelers. Casting square to the pipe, aiming north will put you on sandy ground that can throw up some good plaice. The south side is shallow and full of kelp and very heavy ground but not many fish.
Don’t even think about fishing there if there is any sea on, the waves wash straight over it and I’ve known a couple of people who have been wash and seen others have their gear taken by the waves.
Good luck.
