6.1 · Estuary · Gloucestershire
A classic Severn estuary floodbank mark along Oldbury Naite near Oldbury-on-Severn. Anglers fish from the grass/concrete sea wall over extensive mudflats into the main channel on large tides. Best around the last two hours of flood, high water, and the first of the ebb. Expect extreme tidal range and fierce currents—use 6–8 oz grip leads and streamlined rigs. Summer and early autumn bring flounder, bass, and silver eels; late autumn and winter see whiting and codling. Baits that score include lugworm, ragworm, and peeler crab; squid or mackerel cocktails for winter species. Access is via narrow lanes with limited roadside pull-ins, then short walks along the sea wall. Major hazards are the Severn Bore, very fast-flooding tides, and deep, soft mud—never leave the wall or attempt to access the foreshore. The mark is exposed to wind and weather with little shelter.

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.

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.

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.

Oldbury Naite sits on the upper Severn Estuary in Gloucestershire, just downstream of Oldbury-on-Severn and opposite the sweeping mudflats that make this river famous. It’s a classic Severn shore mark: huge tides, savage currents, and the real chance of bass, smoothhound, and thornback rays in season. Experienced estuary anglers value it for its wild feel and productive flood/early ebb sessions.
Getting to Oldbury Naite is straightforward via the lanes north of Thornbury, with final access on narrow roads and farm tracks. You then follow the Severn Way along the floodbank to choose your stance on the stone revetment above the mud.
The Severn here is turbid and powerful, but it draws migratory and estuarine species across the seasons. Expect better variety from late spring through early autumn, with traditional winter codling/whiting runs in cold snaps.
Bait fishing rules here due to colour and flow; you need sturdy tackle, breakout leads, and clipped-down rigs to cut through the wind and tide. Fish the edge of the channel on the flood and the first of the ebb, adjusting range to find the seams.
Oldbury Naite responds to movement: aim for the last of the flood into high water and the first hour or two of the ebb. The Severn’s range is huge—plan around it rather than fighting it.
This is a serious estuary venue. The combination of steep banks, fast tides, the bore, and deep mud demands caution and preparation.
Facilities are minimal at the mark itself; think of this as a wild, self-sufficient venue and plan accordingly.
Local Severn regulars focus on timing, elevation, and bait quality. Small tweaks make big differences here.
Oldbury Naite lies on the tidal Severn. There is no blanket ban on angling here, but a mix of national and local rules apply. Always check the latest government and IFCA/EA guidance before you go.
