Head to
Wind driftS wind
Northern end

A southerly has held for 6 hours at much the same temperature as the 10°C water. No thermal steer either way, but the drift still stacks food against the northern end — the bank it is blowing into — so start there. This reads the upper water, though — a bottom bait at range feels it far less than a floater or a fish in the margins. Treat it as a tiebreaker between good swims rather than an override — features and angling pressure usually count for more.

How to fish it · for Rainbow
When
Overcast days with a light ripple, cool water; sheltered enough to fish in wind
Where
Start with Red Sedge (8-10) on a As per local method. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Red Sedge (8-10) on a As per local method. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

A fry-imitating pattern stripped through the margins can save a blank in autumn.

Watch for

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
