Northern end
A northerly has held for 13 hours, running colder than the water (5°C air against 10°C water). The end it blows into is taking that chilled surface water, so try the sheltered northern 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.

When
May–September; mayfly peak late May–June
Where
Set up a broadside drift and cover the water systematically. Work Perch Fry on the bob and Minkie on the point.
The plan
Plan A
Set up a broadside drift and cover the water systematically. Work Perch Fry on the bob and Minkie 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
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
