6.0 · Estuary · Bristol
A tidal estuary bend on the River Avon in the Avon Gorge between Sea Mills and Shirehampton. Deep, fast water runs close to the bank with mixed rocky margins and soft mud. Best fished the last 2 hours of flood into the top of the tide (neap to mid-range). Winter brings whiting and codling; summer to autumn sees bass and flounder, with eels and conger after dark. Use strong gripper leads and abrasion-resistant gear; expect snags and floating debris on bigger tides. Access is on foot via paths from Shirehampton Park or Sea Mills; paths can be steep and slippery, and the foreshore is muddy—check tides to avoid cut-off and be aware of wash from passing vessels.

Best available: 21:00-00:00 around the rising tide

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.
Fishable, but pick your timing carefully.

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.

Horseshoe Bend is a classic tidal River Avon mark on the A4 Portway between Sea Mills and Shirehampton in Bristol. The river sweeps into a tight curve here, bringing deep, fast water close to the wall and putting migrating estuary species within easy casting range. It’s a productive, no-nonsense venue for winter codling and whiting and summer bass and mullet, especially into dusk and after dark.
This mark sits on the Portway (A4) alongside the outside of the bend, with fishing from the pavement behind the crash barrier onto a vertical wall. Access is straightforward on foot, but parking needs forethought due to clearway restrictions on the Portway.
The Avon here is a true estuary with heavy salt influence on bigger tides. Expect classic Bristol Channel species with strong seasonality and plenty of small fish in winter.
Strong tidal flow dictates simple, reliable tackle and fresh baits that hold in the run. Most anglers ledger from the wall; the channel is close so big casts are unnecessary.
The Bristol Channel’s huge range and the gorge’s constriction make tide choice critical. Neaps are easier and often fish better; big springs can be unfishable with debris and savage flow.
This is a high-wall, fast-tide, roadside venue—treat it with respect. Keep well behind the barrier, stay visible to traffic and never attempt to access the foreshore.
There are no facilities on the mark itself—plan to be self‑sufficient. Nearby suburbs offer basics within a short drive.
Local anglers keep it simple here: short lobs into the channel edge, fresh bait, and heavy leads that hold. Small details around timing and presentation make a big difference.
This is tidal water, so normal sea angling rules apply, but several important protections are in force. Always check current bylaws before you go.
