June Dawn Sewin Forecast — Teifi (Cenarth)
Cenarth: first light to about two hours after sunrise on a dropping tide is prime for sewin.
On the lower Teifi the main run pushes as the tide falls, and fresh fish stack on the beats above the tidal limit. Concentrate along the association water from just above Newcastle Emlyn down to Llechryd and Cenarth; the river is tidal below Llechryd and the tide-change pulse sets the feeding rhythm.
At dawn look to tailends of pools and fast glides where fish pause after the tide turns. Shallow runs one to three feet deep beside drop-offs and undercut banks are classic sight‑cast water. Broken water at the head of pools after a fresh tide push—especially with a slight colour—produces the best visible takes.
June brings grannom sedge and small mayfly activity, alder and sedge buzzes and the odd March Brown and stonefly through the season. Match that hatch with smaller patterns: Teal Blue & Silver, Medicine Fly, Dunkeld and Butcher work alongside Teifi Terror, Black Pennell and Jambo. Shrimp patterns and Haslam or Hairy Mary are useful when fish key on crustaceans.
Fish smaller sizes than many rivers; size 8 or 10 and low-water doubles are the go-to. For pre-dawn sight work a 12–15 ft leader tapering to 8–12 lb nylon gives stealth and control on low Teifi beats. Dark flies for clear water, orange shrimp styles when the river takes a stain.
A sewin flashes in the dim, follows a floating fly along a shallow glide and slips back into the tail of the pool as the sky palerns.
