5.6 · Estuary · Gloucestershire
A classic upper Severn estuary bank at Elmore Back: a grassed flood embankment overlooking wide mudflats and a fast, deep tidal channel. It fishes best around the flood to high water on spring tides for bass and winter codling, with reliable flounder and summer mullet in calmer spells. Expect a walk along the floodbank, very soft mud (do not leave the bank), powerful currents and occasional Severn Bore; no facilities and exposure to wind—plan carefully around tides and daylight.

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.

Elmore Back sits on the upper Severn Estuary in Gloucestershire, a tidal riverbank stretch famed for huge tides and the occasional Severn Bore. It’s a classic spring-to-autumn flounder and bass venue with challenging currents, short casting, and intimate estuary fishing. The mark rewards careful tide timing, strong tackle, and stealth when mullet are about in summer.
This is a rural hamlet and floodbank section south-west of Gloucester, reached via narrow country lanes. Access is straightforward once there, but parking is limited and you must keep gateways and passing places clear.
The upper Severn Estuary here holds a mix of sea and estuarine species. Bass and flounder headline, with mullet in the warmer months and the odd winter codling in cold years.
Fast tides and heavy silt demand simple, robust sea gear. Short, accurate casting into the near-channel is far more effective than blasting to the horizon.
This stretch is all about reading the tide. The Severn’s range is huge, the flow fierce, and the bore on big springs can make or break a session—and poses a serious hazard.
This is a serious tidal river with lethal mud and a fast, rising flood—treat it with full respect. The mark is not suitable for wheelchair users and can be tricky for those with limited mobility.
Elmore Back is rural with no on-site amenities. Plan to be self-sufficient for food, water, and toilets.
Local anglers fish light where possible and place baits accurately into feeding lanes, not the middle of the river. Keep your footprint small—this is a quiet residential and farming area.
This stretch is tidal and subject to a mix of marine and EA controls. Always check the latest national and local byelaws before you go.
