My advice for Druridge, if you're after the flatties, is go an hour or so before Low water and stand as high on the dunes as you can. Spot an area where the water looks a bit deeper or where it will be deeper once the tide turns. Set up there and cast very short. Low water and the first few hours of the flood are good. But if there are plenty of fish about, any state of the tide can fish. High tide can fish well if you hit the gullies too. If you want codling, night time and a decent sea running is the key.
