You will always get conflicting information about Blyth it has been that way for years and years, nobody can really tell when to fish it. Go along the morning before you are going to fish and find out where the holes are, they change with very little sea Blyth being an open beach. i always used to fish during darkness after the sea has died away a bit, you may have to go a few nights in a row to catch the fish, one night you will get nothing the next whooopeee. And vice versa of course. I always prefered low water but have also had some cracking bags at high water. Always found lug the best bait but also had loads of fish on crab. The size of the tide also effects fishing. If you have got a massive sea running with a big tide and there is a decent hole on thebeach you can catch fish as soon as the bar stops the waves. If it is a small tide dont bother unlss the hole is way up the beach. Blyth will always be an enigma.
