How to use this ranking
The order is a map-planning ranking, not a claim about today's fish population. It favors larger mapped waters and gives survey-backed contours a three-times data-quality boost. Agency population surveys, current regulations, access and recent conditions should make the final decision.

When to fish sea trout in Ireland
- Spring 3–20 ft — Cover shallow stone, eelgrass edges and slightly colored river plumes with spoons or slim coastal wobblers.
- Summer 15–50 ft — Warm surface water pushes most fish deeper or offshore; focus on current-washed points and the cold side of sharp breaks.
- Fall 3–25 ft — Fish reefs and points near migration routes — but mind the closed season: on the Mecklenburg-Vorpommern coast sea trout are protected Sep 15 – Dec 14 (KüFVO M-V), and river mouths carry their own protected zones.
- Winter 5–30 ft — Slow presentations across ice-free reef edges and dark-bottom bays; stable, slightly warmer water is the key.
