Ranked by how strongly flounder show at each mark. The chip on the right is today's live fish forecast.
Reliable on rag/lug or small crab; work the gutters on the flood and at night in colder months.
Common over mixed sand/mud; ragworm or maddies on a short hooklength; works well mid-tide up to high.
Common on the sandy areas; ragworm/madder lug on a simple running ledger works well, especially around mid-tide.
Catches from the shallower surf zone, especially on smaller floods; rag, lug or small crab baits; try moving to find patches.
Common in the bay; lug/rag or mussel, light leads and keep baits on the deck.
Year-round with peaks in autumn; rag/lug or small fish strip; keep leads just heavy enough to hold in the run.
Aim for mixed sand/shingle and the edges of weed; ragworm or lug on light leads works well on smaller tides.
Gutters and the lower beach produce fish on rag/maddie or small lug baits; a moving rig or light ledger can help in calmer seas.
More likely closer to the Ogmore outflow and along the edge of the estuary; rag/lug on a short hooklength, light leads when possible.
Close-in in the shallows and channels; rag, maddies or lug on a 1–2 hook flapper works well.
Often close in; lug/madder or rag; keep leads light enough to fish the inner surf without burying.
Picks up in calmer spells inside/near the channel; ragworm or small crab on light(ish) leads when tide eases.
Fish the sandier runs near the inner harbour/edges with rag/lug; better around neaps and after rain.
Occasional, especially after rain/coloured water; rag/lug or small fish baits. Fish the gullies on mid-tide.
Occasional on sandy runs close in; rag or small fish baits on a simple running ledger, best around slackening tides.
Best close in on mixed sand/shingle; worm or small crab baits, slow retrieve can help.
Often close in, especially around any freshwater seepage; rag/lug or small fish strip baits.
In sandy seams and calmer corners; rag or small fish strip on light leads. Often better on smaller tides or when run is dropping.
On the sand/shingle margins, especially with a bit of tide run; rag/lug baits; useful ‘filler’ species when rays aren’t showing.
Closer in on mixed sand/shingle; lug or rag, especially around gutters on the flooding tide.
Occasional over sandier stretches; rag/lug baits on a simple running ledger, often best around mid-tide.
Closer-in on ragworm/lug; look for calmer corners and small gutters on the flooding tide.
Pick up over the adjacent sandier ground; ragworm or small fish strip, especially around tide changes.
Pick them up on worm baits, especially in coloured water; don’t overcast—often closer in around gently shelving ground.
Occasional on cleaner patches among the rough; rag/crab baits fished static around slack water.
