Wind driftSW wind
North-eastern end
A southwesterly has held for most of a day, running warmer than the water (17°C air against 15°C water). Expect fish at the north-eastern end — the bank it is blowing into — where the drift piles food, colour and warmth together. 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
March–June, then September
Where
Start with Buzzers (12-14) on a slow, natural presentation — check locally for the preferred method. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses.
The plan
Plan A
Start with Buzzers (12-14) on a slow, natural presentation — check locally for the preferred method. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses.
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.
