Wind driftSW wind
South-western end
A southwesterly has held for 7 hours, running colder than the water (8°C air against 14°C water). The end it blows into is taking that chilled surface water, so try the sheltered south-western end instead — off the back of the wind, where the undertow returns food along the bottom. That chill sits in the top of the water, though, and the bed is slower to feel it — on a bottom bait it is the undertow, not the temperature, that puts you at this end. 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–November
Where
Start with Booby (10–12) — on the point. 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 Booby (10–12) — on the point. 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.
