How to fish it · for Sea Trout
When
June through September; July into August prime. Night fishing from full dark when water rises above 13°C. NRW classifies the sewin stock 'At Risk' across Wales — fish carefully if at all, treat C&R as a default. A good spate in July or August can still produce — runs are condition-led.
Where
Lower and middle Teifi pool tails through to the Cardigan tidal limit.
Method
Across-and-down on a floating line with small wets — Medicine, Teal Blue and Silver, Stoat's Tail. Steady swing through the tail-outs, never hurry.
Kit
10 ft #6/7, floating line, 8 to 10 lb fluoro tippet. Spare leader on a wrist spool. Headlamp sparingly; let your eyes adjust.
Why this works
Excellent — conditions well-balanced, with time of day particularly in your favour.
Likely species
Stoneflies
Caddisflies
Gammarids

Ranked for today
Fly box · Sea Trout
BS
Black & Silver TubeTop
1-2 inch · Tube
In deep pools and dark water, silhouette and contrast do the work colour cannot. A fly that reads as black against depth is enough. Fish it broadside, hold the swing, let it hang at the dangle — that is when the best fish take.
Medicine Fly
Medicine Fly
8-12 · Streamer
Slim and mobile — fished sunk through the pool when surface work is not producing. Consistently takes fish that will not come to the surface.
SF
Snake Fly (Black)
2-4 inch · Streamer
A mobile eel-like profile that undulates through deep pools — effective when sea trout are lying deep and not responding to conventional wets.

Seasons & zones
  • Salmon 1 April → 17 October
  • Trout 3 March → 30 September

Sea trout: Variable seasonal (2026) — NRW At Risk classification. The Teifi holds sewin but stocks have declined across the wider West Wales catchment. Runs are condition-led — a good spate in June or July can produce excellent night fishing; a dry summer is a write-off. Historic coracle fishing tradition on sewin; the modern fishery demands catch-and-release discipline.

Salmon: Negligible (2026) — NRW / EA 2024 Salmon Stocks Assessment classifies this Welsh principal salmon river 'at risk' — egg deposition below Conservation Limit. All Wales byelaws (in force 2020-2030) make catch & release mandatory. Conservation priority; not a salmon fishing destination. The Teifi remains a famous fly fishing river but salmon are scarce.
