Head to
Wind driftSE wind
South-eastern end

A southeasterly has held for most of a day, running colder than the water (11°C air against 14°C water). The end it blows into is taking that chilled surface water, so try the sheltered south-eastern 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 Trout
When
May-August
Where
With limited drift, anchor or fish static from sheltered positions. Work Gorgeous George on the bob and Pennel on the point.
The plan
Plan A

With limited drift, anchor or fish static from sheltered positions. Work Gorgeous George on the bob and Pennel on the point.

Plan B

If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.

Watch for

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

Bank, sheltered shores

Strong wind makes boat fishing difficult — sheltered bank spots near lee shores will fish best.
