A southwesterly has held for 12 hours, running colder than the water (5°C air against 7°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.
