Black & Silver Tube1-2 inch
In deep pools and dark water, silhouette and contrast do the work colour cannot. A fly that reads as black against depth is enough. Fish it broadside, hold the swing, let it hang at the dangle — that is when the best fish take.

Why this works
Good — water temperature is working for you, but time of day is the limiting factor today. ⏰ Sea trout become most active after dark, but this stretch closes at 21:00 — before that window fully opens. Fish hard in the last legal hour: overcast skies and warm evenings can bring fish on early even in fading light. ⏰ Sea trout become most active after dark, but this stretch closes at 20:57 — before that window fully opens.
