An easterly has held for 19 hours, running colder than the water (11°C air against 13°C water). The end it blows into is taking that chilled surface water, so try the sheltered 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.
Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
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.
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Windy conditions suit anchoring in productive areas rather than open-water drifting.
