I have only ever fished for cod on these marks in the winter and summer , but there are some very big deep gullys and as the tides are quite big you should have no bother finding the best of them , but you have some of the worst ground and a lot of kelp, so weedless or a light float set up would be the best way to go also you will have the sea away as the forecast is for north/easterly winds which is not ideal for summer fishing here as the flatter the better.Anyway the main thing is you go and enjoy it , good luck .
