How to fish it · for Trout
When
May-September; peak June-August
Where
Work Green Peter on the bob and Bibio on the point.
The plan
Plan A

Work Green Peter on the bob and Bibio 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

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Boat — at anchor

Windy conditions suit anchoring in productive areas rather than open-water drifting.

Sea trout: Variable seasonal (2026) — Machair loch systems of South Uist once famous for sea trout; stocks have declined sharply in line with the wider Hebridean pattern (sea-lice pressure, reduced marine survival). Still fishable in the right conditions but cannot be promoted as reliable. Local knowledge and timing essential.
