6.3 · Estuary · Bristol
Classic upper Bristol Channel estuary mark on the north bank of the River Avon beside the remains of the old Shirehampton railway bridge. Anglers fish from the firm foreshore and paths around Lamplighters Marsh, casting into a deep, fast shipping channel on the outside of Horseshoe Bend. Huge tidal range: strongest flow mid-flood and mid-ebb; best fished the last two hours of the flood and first hour of the ebb, with neaps most comfortable. Ground is mixed silt, mud and scattered stones, with snaggy debris near the old bridge footings. Use strong tackle and grip leads (6–8 oz on springs). Worm and crab baits score for flounder and bass; lug/squid cocktails for winter whiting and codling; bread or small rag for mullet. Night fishing is productive for eels, whiting and codling. Take great care with mud, the rapidly rising tide and passing shipping.

Fair conditions. Best available around 21:00-00:00 around the rising tide, but no window reaches the strong threshold today. Good chance of Bass and European Eel.

Where the data comes from. Weather and sea-state readings come from the Met Office and Open-Meteo forecast models, refreshed several times a day. High and low water are taken from tide-station predictions for this stretch of coast.
How the score works. Each window is scored 0–100 from the signals that most reliably move fish inshore: tide movement (a running tide carries food, so the last of the flood and first of the ebb are usually the prime spells), wind speed and direction (onshore wind stirs food into the surf — up to the point it makes fishing hard), sea state (a little wave and swell movement helps, heavy swell hurts), and weather — rain, temperature and light. Behind the headline number we score bite opportunity and comfort separately, and run a separate safety check on wind and swell. The size of the tide counts too: spring tides move more water than neaps, so the tidal range for this stretch of coast is weighed alongside the tide's direction, your target species and this mark — and unusually big springs strengthen the safety check, because the water rises faster and covers more ground.
Your target species counts. Pick a species below and the score also weights what we know about it — its season, preferred sea temperature, tide stage and sea state, and whether it feeds by day or night.
The rating is guidance, not a guarantee — conditions change fast on the coast, so always judge the sea in front of you before you fish.

Strong spring tides — the sea rises faster and reaches further up the shore than usual, so allow extra margin on access routes and cut-off points.
The fishing rating combines opportunity and comfort. Always check local sea conditions; the safety check is guidance, not a guarantee.
Spring vs neap tides. Spring tides have a larger difference between high and low water, so more water moves on each tide — usually stronger flow that stirs up food and gets fish feeding. Neap tides have a smaller range and generally gentler movement. The range here is compared with what is normal for this stretch of coast, and the cycle swings between springs and neaps roughly every week, following the moon.
Big spring tides: the water rises faster and covers more ground than usual — double-check access routes and cut-off points before you fish.

Shirehampton Railway Bridge is a classic upper-estuary Bristol Channel mark on the north bank of the tidal River Avon, a short stroll from Shirehampton village. It offers powerful tides, coloured water and real chance fishing for codling in winter, bass year-round, and estuary species in season. The mix of hardstanding, access, and estuary character makes it a reliable, convenient venue for locals and visiting anglers.
This mark sits along the riverside path by Shirehampton, close to the Severn Beach Line railway and commonly referred to by locals as the "Railway Bridge" stretch. Access is straightforward with public transport and on-street parking near the river.
You’re fishing a powerful, muddy upper-estuary with a broad seasonal species mix. Expect lots of small fish with genuine chances of better codling and bass when conditions align.
Ledgering dominates because of the flow; keep it simple and strong. Aim to hold bottom, present clean baits, and avoid the worst snags with sensible rigging.
The River Avon here is ruled by the Bristol Channel’s huge range—tide choice makes or breaks the session. Work with the flow, not against it.
Treat this as a serious estuary venue: fast currents, deep water and dangerous mud. Fish only from firm ground and keep an eye on the tide.
Shirehampton offers convenient amenities within a short walk. Plan self-sufficiency during night sessions.
Small venue quirks and habits often outfish brute force. A few local tricks can save a slow tide.
This is tidal water outside the Floating Harbour—sea fishing is generally permitted from public access. Still, a few rules and good practices apply.
