Cod are the fish that make winter shore fishing worth doing, and autumn is when it all starts. Through the summer they are out in deeper, cooler water and effectively out of reach from the beach. As the inshore water temperature drops through autumn they move back in, and from around October a shore-caught cod becomes a realistic proposition again.
Water temperature is the trigger
Cod prefer cooler water than most of what we catch from British beaches. The moment inshore temperatures start dropping properly, usually from late September into October depending on where you are, they push in.
The north east and the east coast generally see cod earlier and in better numbers than the south west. If you are on the south coast you are looking at a later, thinner season and you should set expectations accordingly.
Rough seas bring them in close
Cod fishing is one of the clearest examples of bad weather being good fishing. A big sea churns the bottom, dislodges worm, crab and shellfish, and cod come in close to hoover up what the swell has turned over.
The classic conditions are a strong onshore wind, a big coloured sea, and fishing into dark. Calm clear water in daylight is usually the worst combination you can pick.
The corollary is that you have to be sensible. A big autumn sea on an exposed mark is genuinely dangerous. Fish with someone, use a flotation aid, and never turn your back on the water.
Marks that produce
Rough ground. Cod feed over broken, snaggy bottom where the food is, and if you are not losing the occasional rig you are probably not fishing the right ground.
Beaches with a mixed bottom, piers, breakwaters and rock marks all produce. On a storm beach, look for the gutters and the areas where the swell is doing the most work.
Local knowledge counts for a lot here. Cod marks are specific and the difference between a good and a poor mark on the same stretch of coast can be enormous.
Bait: big and smelly
Cod have big mouths and they are not delicate feeders. Big baits catch cod.
Lugworm is the backbone of cod fishing, and a proper bundle of it, not two on a hook. Black lug is the premium option and worth the cost. Peeler crab is outstanding in autumn while it is still available. Squid is reliable and it holds together on a long cast.
The classic cocktail of lug and squid is a cliche because it works. Big bait, wrapped properly with bait elastic so it survives the cast and the surf.
Rigs and tackle
Pulley rigs are the standard for rough ground because they lift the lead clear on the retrieve and reduce snagging. A single big hook, often a 3/0 to 6/0, matched to the bait size.
Rotten bottom setups, where the lead is attached on a weak link, save a lot of tackle and a lot of frustration on snaggy marks. Learn to tie one before you need it.
Tackle needs to be up to casting a big bait into a rough sea. This is not finesse fishing.
Fish into darkness
Cod feed better in low light and after dark, particularly in clearer conditions. The two hours either side of high water into dark is the standard productive window on many marks.
That means a decent headtorch, spare batteries, and enough warm clothing to sit out on an exposed beach in an autumn gale. The fishing is often good exactly when being there is least comfortable.
Handle and take responsibly
Cod stocks around parts of the UK have had a difficult few decades and the picture varies enormously by region. There are minimum sizes and in some areas further restrictions. Check the current rules where you are fishing.
Take a fish for the table if the rules allow and you want to, but there is no need to fill a bag. A single good cod is a fine thing and the rest can go back.
A first autumn cod session
Wait for an onshore blow. Fish a rough ground mark two hours before high water into dark. Big lug and squid baits on a pulley rig, two rods if the mark allows. Expect to lose gear. Take a flask and more clothing than you think you need.
Mike Talbot grew up in Cornwall and had a rod in his hand before he was tall enough to reach the rod rest properly. His early fishing was mackerel from the harbour wall and plaice on the beaches at low tide, but bass took over in his late teens and have never really let go.
He moved to Pembrokeshire in his thirties for the coastline as much as anything else, and now fishes a mix of rock marks, estuaries, and boat trips across West Wales and the Bristol Channel. He targets bass on surface lures through summer, drops down to soft plastics and HMDs through autumn, and fills the winter with wrasse fishing on the rock marks when conditions allow. Personal best bass: 8lb 4oz, caught on a floating stickbait at first light on a calm August morning.
