Water temperature for Sea Trout
Ideal14°C est.ideal 8–15°C
0°14°28°
How to fish it · for Sea Trout
When
From dusk into the first half of the night.
Where
Deeper pools and slower glides · hold water and current seams.
Method
Fish dark patterns on a sink-tip or lightly sunk line, especially near structure.
Kit
10 ft #6/7 rod, floating line with a sink-tip option, 8–10 lb fluoro tippet for the swing.
Why this works
Excellent — water temperature is right today, though insect activity could be better. ⏰ Sea trout become most active from an hour before dusk. This stretch closes at 22:15 — your legal window captures the start of the best fishing. Fish the last 90 minutes hard. Overcast evenings extend the effective window.

Sea Trout fly box
Top
1-2 inch · Tube
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.
2-4 inch · Streamer
A mobile eel-like profile that undulates through deep pools — effective when sea trout are lying deep and not responding to conventional wets.
