Winter in the UK may feel still and quiet, but trout and grayling don’t stop feeding. They move slower, feed deeper, and become more selective. With the right pattern at the right moment, you can keep catching all season long.
Below are the 7 most reliable winter flies used across UK rivers, why each one works, when to fish it, and how to get the most from it.
🟣 1. Tungsten Pheasant Tail Nymph – “The Winter Workhorse”
A classic in every season, but a go-to winter nymph for UK rivers. Cold water slows insect activity and pushes trout toward the bottom where food drifts slowly. This pattern sinks quickly, stays slim, and imitates a huge range of natural nymphs.
Why it works
- Tungsten bead helps it reach feeding depth fast
- Quill-like body imitates olives, baetis, and general nymphs
- Deadly for grayling in 1 to 3 ft deep glides
Fish it
- As your point fly on a Euro-nymph rig
- With long, controlled drifts
- In clear or slightly coloured water
Best conditions
✔ Cold mornings
✔ Slow glides
✔ Deep runs

💗 2. Pink Shrimp – “Grayling Candy”
When water gets icy cold, grayling want colour and pink is their favourite. This pattern is a staple across the UK during December through February, especially on chalk streams and slower limestone rivers.
Why it works
- Mimics freshwater scuds
- Pink stands out in winter’s low light
- Soft dubbing pulses naturally in the flow
Fish it
- As a dropper fly
- On pressured chalk streams
- In slow, glassy flows
Best conditions
✔ Clear water
✔ Bright or cold mornings
✔ Grayling hotspots

🟤 3. Hare’s Ear Jig Nymph – “The Natural Choice”
When trout and grayling refuse bright patterns, this is the confidence fly to switch to. The hare’s ear looks like everything and nothing at the same time, and that ambiguity is exactly what selective winter fish want.
Why it works
- Looks like everything and nothing
- Triggers eats from spooky or selective fish
- Great when winter insect activity is subtle
Fish it
- In shallow riffles
- With ultra-light tippet
- Paired with a heavier anchor fly
Best conditions
✔ Midday warmth
✔ Clear water
✔ Overfished beats

✨ 4. UV Perdigon Nymph – “The Winter Laser Bullet”
Perdigons sink fast and cut through the water column like tiny darts. UV bodies make them perfect for murkier winter rivers where fish need a little more visual stimulus to commit.
Why it works
- Ultra-slim profile means a fast sink rate
- UV flash gets noticed in low light
- Perfect anchor fly for Euro-nymphing
Fish it
- Tight-line methods
- Deep pools
- Coloured or cloudy water
Best conditions
✔ Fast runs
✔ Deep pockets
✔ Heavy winter flows

🪶 5. CDC Winter Dry (Size 18–22) – “The Surprise Winter Winner”
Yes, you can catch fish on dries in winter. Tiny midges still hatch during mild afternoons and trout often look up for them. CDC holds float beautifully in icy water and lands with very little disturbance on the surface.
Why it works
- CDC holds float beautifully in icy water
- Imposes very little disturbance
- Perfect for micro-hatch days
Fish it
- On a long leader
- With gentle presentations
- In glassy, calm stretches
Best conditions
✔ Mild afternoons
✔ Gentle hatches
✔ Flat glides

⚫ 6. Black Bug Jig – “The Deep-Winter Weapon”
When fish hug the riverbed and refuse to move, this is your surgical strike. The black bug is heavy, compact, and subtle in a way that lethargic winter fish find very hard to ignore.
Why it works
- Heavy, compact, bottom-searching pattern
- Subtle profile is irresistible to lethargic fish
- Great for probing deep feeding lanes
Fish it
- As your single, heavy fly
- With slow, steady drifts
- In deep winter pools
Best conditions
✔ Freezing days
✔ High water
✔ Slow pools

🟢 7. Micro Winter Woolly Bugger – “Streamers Still Win”
Downsized streamers trigger aggression when nothing else works. This smaller version keeps a delicate profile while offering plenty of movement. Even lethargic trout will often move for a slowly stripped woolly bugger when they ignore everything else.
Why it works
- Marabou tail moves even in slow currents
- Great for covering water quickly
- Can draw strikes from sleepy trout
Fish it
- On 4 to 5 ft of tippet
- Slowly retrieved
- Near structure and slow banks
Best conditions
✔ Stained water
✔ Prospecting new beats
✔ Low, cold afternoons
