Grayling fly fishing in Autumn with a focus on the beautiful Welsh Dee

Grayling fly fishing provides a fantastic opportunity to continue fishing when the trout and salmon fishing seasons close and avoids having to hang your waders until spring.

After a brief introduction, this article will cover all the key elements of how to catch grayling in autumn, i.e.

• Essential tackle requirements for grayling fly fishing
• Grayling fly fishing tactics for September, October, & November

Introduction

A grayling is a beautiful fish with a silvery body, a distinct ‘rainbow’ coloured dorsal fin, and a graceful demeanour until hooked!

Thus, it’s not surprising that the grayling is often called the…

“Lady of the Stream”

The grayling fishing season can vary slightly between rivers but is similar to that for coarse fish. On the Welsh Dee, a river I regularly fish, the grayling fishing season starts on the 16^th of June and runs through to the 14^th of March.

Grayling are members of the salmon family but unlike their relatives, grayling spawn in spring, and thus, come into prime conditions during autumn and winter. As such, they can often be relied upon to feed when the temperature drops to freezing.

Consequently, if you’re hardy enough, you can still fly fish for them when there’s snow on the ground or during a long spell of freezing weather.

So, let’s begin by briefly covering what fly fishing you’ll need to begin fly fishing for grayling…

Grayling fishing tackle requirements

If you fly fish for trout on rivers, you’re likely to have all the grayling fishing tackle needed. Outlined below are the essential fly fishing tackle requirements to cover dry, wet, and nymph fly fishing for grayling.

Grayling fly fishing rod & reel

A standard 9 to 10ft fly rod rated from 3 to 7wt with an appropriately matched reel will allow you to fly fish for grayling using dry flies, wet flies and nymphs.

My preference for dry and wet fly fishing for grayling is a soft-action, 9ft-6”, 5wt rod. Whereas, for Euro / Czech nymphing I use a lightweight 10 to 11ft 3# fly rod. Currently, I favour an 11ft 3# Vision Nymphmaniac fly rod matched with a Vision XLV nymph reel.

Fly Lines

The fly line should be matched to your rod. For wet and dry fly fishing I use a WF5 floating line (Airflo Lake Pro WF5). A standard dry fly line matched to your fly rod can be used for nymphing. However, I prefer to use a low-diameter (0.6mm) specialist nymphing fly (Airflo SNF Euro Nymph) because it helps with bite detection during windy conditions.

Leader & Tippet

For grayling dry fly fishing I use a 12ft copolymer or monofilament 3X tapered leader and add 3ft of 3 or 4 lb fluorocarbon tippet. On windy days switch the leader from a 12ft to a 9ft 3X tapered leader.

When fishing a team of three wet flies or spiders I use a 7ft copolymer or monofilament 5X tapered leader and add 6ft of 3 copolymer tippet for two droppers.

For Euro / Czech nymphing use a simple leader system composed of 6 to 9ft of 4lb fluorocarbon (Airflo Sightfree G3 Fluorocarbon), with 2 or 3 droppers spaced 18″ apart.

Fly fishing accessories:

• A landing net with a magnet release clipped on the back of your jacket
• A bottle of dry fly floatant – I use Gink
• Line degreaser – I use Fulling Mill Fuller’s Mud
• Something to dry the fly – I use a dry microfiber cloth
• Insulated waders
• Neoprene gloves and warm clothing for when it gets cold.

Now the essential grayling fishing tackle requirements are covered, let’s get into the ‘MEAT’ of fly fishing for grayling during the autumn months…

Grayling fly fishing tactics for September

Autumn can be a confusing time because two dates can be used to mark the start of autumn:

• 1^st of September, which is the meteorological autumn, or
• the autumn equinox, which is the 22^nd of September this year.

Also, September is a transitional month, where the weather transitions from a summer to an autumnal feel. As such, the weather in September can vary from an Indian Summer (unseasonably warm, dry weather) to a cold, wet, and windy affair.

Consequently, you’ll need to adapt your grayling fly fishing tactics to cover the full spectrum of river conditions from drought to flood.

Fortunately, large numbers of grayling can be caught as the temperature cools during September because they start to feed aggressively to fatten up for the leaner months ahead.

Double hooks when fishing a team of flies or nymphs are a distinct possibility at this time of year…

Fly fishing for grayling on mild days in September

In September, there is still a variety of natural flies that you are likely to see hatching on UK rivers…

Mild, overcast days when the river is running clear usually present a great grayling dry fly fishing opportunity.

are LOST on stumbling to the river bank.

Carefully approaching the river is the way to proceed…

It will enable you to spot any large grayling lying in shallow water. Then, take some time to observe your quarry to determine…

• whether it’s feeding,
• what fly is being taken,
• and how best to present the dry fly without spooking it.

At best you’ll only get one or two casts before it’s spooked and dashed for cover.

If there’s no evidence of it feeding on dry flies it’s worth selecting an olive imitation and having a cast…

Often it will have been just lying there waiting for some food to present itself.

Even in the absence of any rising grayling, it’s possible to tempt grayling that are feeding on the riverbed with the dry fly, especially in water less than 4-5ft deep.

Wet fly fishing for grayling…

Fishing a team of wet flies and/or spiders for grayling can produce some fantastic sport when dry fly fishing fails. My preferred locations for wet fly fishing are fast riffles that run into large pools and the tails of pools.

I normally fish a team of three flies on a tapered leader with the flies spaced 3ft apart on a 3lb copolymer tippet (total leader length 15ft). In windy conditions, I shorten the leader and drop to fishing one or two wet flies. This approach has served me well for over 20 years.

Wet fly selection for September depends on what flies you expect to see on the river. However, if you don’t know then my recommendation would be to start with the following three-fly cast on 3lb copolymer (point: #14 Black Hopper; middle dropper: #14 March Brown Spider; top dropper: #16 pearl ribbed March Brown spider)… 

because they continue to serve me very well during September.

Fly fishing for grayling on cold September days

On days during September grayling will be predominantly feeding aquatic insects (Caddis larvae, upwing nymphs, freshwater shrimps, etc.) close to the riverbed. On these unseasonably cold days, the best approach to catching grayling will be fishing close to the riverbed with a team of nymphs.

Short-range nymphing techniques (Euro nymphing or Czech nymphing) are usually the best approaches to a successful day fishing for grayling.

If the river is running clear, I find fishing a team of nymphs that closely resemble the size and colour of the natural aquatic insect present in the river works best. Sometimes a flash of colour in one or more of the nymphs being fished improves the catch results.

For example, the following three nymphs fished on 4lb fluorocarbon leader (point: #12 pink collar pheasant tail nymph 3mm TB; middle dropper: #16 Hare’s ear quill nymph 1.5mm TB; top dropper: #18 claret nymph 1.5mm TB). 

If the river is coloured I normally use large colourful nymphs (#14 to 10). Check out the following post with more information on the best grayling flies for September…

Grayling fishing tips for October

It’s such a beautiful time to be out grayling fly fishing.

Temperatures continue to fall during October and at the end of the trout season, my focus turns to fly fishing for grayling.

In October, fly hatches on UK rivers become less prolific. However, on mild days you’re still likely to see any of the following flies on mild days.

Fly hatches occur during the warmest part of the day. Therefore, be prepared to switch to the dry fly from either nymphing or wet fly fishing because…

‘Happy Hour’ often ends as quickly as it starts!

October is usually a wetter month than September because of the weather fronts rolling in off the Atlantic. As such, river levels are higher and fly fishing with nymphs for grayling often yields the best results.

Grayling fly fishing tips for November

In November, the last month of Autumn, the weather in the North West can range from a mild 16^oC to a wintery sub-zero. For mid-November, the long-term historical average high & low temperatures are 9^oC & 5^oC, respectively.

The clocks have been turned back but nature is unaware of this…

Therefore, arrive at the river an hour earlier at the beginning of November to avoid missing the brief, all-important fly hatches…

On mild days (ca. > 10^oC) when the river is running clear it’s likely you’ll see grayling taking flies at the surface. Under such conditions, you can have a…
