Why Fish for Grayling in Summer?
Traditionally, grayling are associated with autumn and winter, but that’s only half the story. From June onwards, grayling feed actively on rivers across the UK. Long, warm evenings see hatches of sedges, midges, and terrestrials, and grayling make the most of this abundant food supply.
Fishing for grayling in summer means:
- Crystal-clear water, perfect for sight fishing
- Long evenings for after-work sessions
- The thrill of catching grayling on small dries and technical nymph rigs
What Do Grayling Eat in Summer?
Grayling are opportunistic feeders and their summer diet includes:
- Caddis (Sedges): Evening sedge hatches often spark frenzied surface activity.
- Terrestrials: From July onwards, beetles, black gnats, and aphids fall onto the water.
- Midges: Even when nothing obvious is hatching, midges keep grayling sipping steadily.
- Freshwater Shrimp: In bright light, grayling drop deep and forage on shrimp.
Best Flies for Summer Grayling
Make sure your fly box includes:
Dry Flies
- CDC Beetle
- Black Gnat (#18–20)
- F-Fly (Hare’s Ear or Olive)

Nymphs & Bugs

Suitable Tackle for Summer Grayling

- Stay Stealthy: Low, clear rivers make fish spooky.
- Long Leaders & Fine Tippets: Drag-free drifts are critical.
- Duo/Dry-Dropper: A visible dry with a nymph dropper works wonders.
- Embrace Modern Nymphing: Short, precise Euro-nymph drifts excel in pocket water.
- Spiders Work Well: In skinny, fast or pocket water, a couple of spiders fished through will often result in a fish
The Lifestyle Element
