Newnham-on-Severn

4.9 · Estuary · Gloucestershire

A powerful tidal estuary mark on the River Severn beside Newnham-on-Severn, fished from firm ground along the village riverbank and near the old ferry/slip. Expect extreme currents, fast-flooding tides, and soft mud—plan around the tide tables and the Severn Bore. Best results come on neap tides for sight-fishing mullet in clearer water, and on small-to-mid springs for bass and flounder along channel edges and eddies.

Scores and best windows are weighted for .

Met Office Met Office · Open-Meteo

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.

· windows & tide

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.

Premium Mark Insight

Locked

Newnham-on-Severn is a high-potential but tide-critical River Severn estuary mark. It fishes best when you work with the flow rather than against it: clearer neaps for mullet and micro-species, and small-to-mid springs for bass, flounder and eels along channel edges, gutter mouths and eddies. The main decision is timing — avoid bore surges and the fastest water, and concentrate effort around easing stages of tide.

  • Know when Newnham is worth fishing — and when the tide is against you.
  • Pick neaps for mullet and small-to-mid springs for bass and flounder.
  • Target the ferry/slip area, channel edges and close-in muddy gutters with purpose.
  • Avoid wasting time in the full Severn push — fish the easing water.
  • Use the right species plan for bass, flounder, eels, mullet and smelt.

Catch Potential 5/10
Species Variety 5/10
Scenery & Comfort 7/10
Safety 3/10
Accessibility 5/10

Flounder 8/10
Tip: Muddy banks and gutter mouths; lug or rag tipped with fish on strong grip leads. Fish last 2 hrs of flood and first of ebb when flow eases. Best autumn–spring; many bites close in.
European Eel 7/10
Tip: Warm evenings on flooding tide into first of ebb. Ledger worm, fish strip or offal close to margins and eddies; summer–early autumn. Handle carefully and release.
Bass 6/10
Tip: Peeler crab, rag or fish baits into current seams/eddies; lures in calmer spells. Best 2 hrs around HW on neaps, summer–autumn. Avoid bore surges.
Mullet (Thin-lipped) 6/10
Tip: Summer on clearer neaps. Small spinners tipped with Isome/worm, worked along surface slicks, creek mouths and eddies on the flood/early ebb. Stealthy approach.
Common Goby 5/10
Tip: Micro baits (worm slivers) on size 18–20 hooks right on the edge of the mud at slack water. Best on neaps when clarity improves.
Sand Goby 5/10
Tip: Muddy margins; size 16–20 hooks with tiny worm/shrimp. Fish slack windows around HW/LW with micro-ledger or small float tight to the edge.
European Smelt 4/10
Tip: Late winter–early spring on neaps after dusk. Tiny fish strips or size 10–12 Sabikis worked midwater along channel margins during the slower tide.
Mullet (Thick-lipped) 4/10
Tip: Occasional in warmer months on neaps; bread flake under a float or small spinners. Target quiet eddies/outflows on the flood; light lines, stealth.
Sea Trout 3/10
Tip: Dusk into dark as tide eases; small spoons/spinners in eddies and crease lines. Spring–summer. Check local bylaws/permissions for migratory fish.
