Sea Trout Fishing: Complete UK Guide
Sea trout fishing is the most atmospheric experience in UK angling, wading a dark Welsh river at midnight, listening for the splash of a running fish. Sea trout are the same species as brown trout, but migratory. Night fishing is the tradition, and those who try it are hooked for life.

How to Catch Sea Trout
A practical guide for weekend anglers: from choosing your method to landing your catch.
- 1
Fish at night
Night fishing from dusk to dawn is the traditional and most productive approach. Sea trout are more active and less wary after dark.
- 2
Choose your method
Fly fishing is the traditional approach, using surface lures and wet flies. Spinning with Toby, Mepps, or small soft plastics also works, especially in estuaries.
- 3
Select your flies or lures
Surface lures like the Gurgler and Mouse pattern at night. Traditional wet flies: Medicine, Alexandra, Teal Blue & Silver. Use dark patterns at night.
- 4
Time your fishing with the tides
Sea trout move upstream on incoming tides. The best fishing is timed to the rising tide, particularly on neap tides.
- 5
Stay safe at night
Use a head torch with red filter, carry a wading staff and wear a life jacket. Know the river before fishing it in the dark.
