top advice by gary you could also try whitley beach or tynmouth beach both pretty clean beachs ,best advice plonk your self next to the lads fishing not to near and talk to them they will be only to willing to help out,or you could always join a local club like whitley,billys at n/s,tynemouth. davy.
Top advice from Gary and Davy, Tynemouth beach is mostly low water marks too,
tynemouth is my local beach and where is put in most of my time, some parts a clean some mixed ground, it is a very shallow beach but you will be suprised at what gets caught here.
in the middle of the beach you will notice a set of rocks. known as bears head, this is straight down from the park hotel. you have 2 marks here worth fishing with two nice holes.
1. Stoney Bottom - best fished in medium tides otherwise the water empties out too much and the fishing dies a death, this is to the left you will see the hole when the sea gets up cant miss it. short casts here as you can cast over the fish.
2. Barge bottom - this is to the right again a cast of 40 yards or so is best and you will see these holes when theres a bit sea on.
both of the above fish well in a north/ north eastly sea but not too big as you will struggle to hold bottom 4-6ft is more than enough.
in the middle you will not a long flat skeer, this is Stoney skeer, walk to the end and cast as far as you can towards the horizon this is accesible on the bigger tides and can fish well after the water ahs emptied out of stoney and barge bottom.
towards the bathing pool you have the skeer knows as bathing pool skeer. best fished in a south eastly sea. can either fish of the skeer itself, but i prefer to be back on the beach casting up the gulley that runs along side it.
hope this helps. there are other marks that can be fished but for clean ground those 3 are your best bet. when the seas away i am generally on tynemouth i dont mind sharing info with people. everyone ahs to start somewhere.
