84,012-acre Youghal Bay. Harbour saltwater fishing map with official INFOMAR survey bathymetry, measured-cell fishing spots, official fish evidence, seasonal forage guidance, access context and current-rule links. The harbour trip-scale survey reach of Youghal Bay, retaining only official survey-backed seabed cells that pass the Ireland release gates. The water tops out around 255 ft. The depth chart comes from INFOMAR (Geological Survey Ireland and Marine Institute) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
Drawn out, this is 83,797 acres of water rimmed by 71.7 miles of bank. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 5% of the surface — that's where the groceries are. Call it 20.8 mi long by 10 mi wide at the broadest reach. The nearest mapped water is Dungarvan Bay - West, 6 mi to the northeast.
Marine Institute spawning, nursery, observation and range layers support the principal surveyed pelagic and groundfish. IFI's national and regional sea-angling publications support additional habitat-compatible recreational targets. This is occurrence and search guidance, not equal abundance, a section-level population estimate or a promised catch. The roster may combine exact-water monitoring with habitat-filtered official regional evidence; it does not imply that every species is equally abundant throughout the mapped section.

Spring puts european seabass in skinny water — 3 to 25 ft is the zone. Warm water sends them out to 2 to 30 ft; cold water stacks them in 10 to 55 ft. Shoreline point is the standout, a point at roughly 23 ft, rated good for fall european seabass. Plan around early morning and the evening in the warm months. A surface lure or a paddle-tail soft plastic covers the summer program.

|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Shoreline point (23 ft) | Paddle-tail soft plastic, Shallow minnow plug |

| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (23 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
Spring atlantic mackerel on Youghal Bay - Harbour hold shallow, usually 5 to 45 ft. They move out to 15 to 80 ft in summer and finish the year down in 30 to 120 ft. Put Sharp break first on the milk run — a drop-off near 78 ft that grades good for summer. The feeding windows run early morning and the evening. The summer box starts with a feather rig or a small vertical jig.

Spring puts atlantic herring in skinny water — 5 to 25 ft is the zone. Warm water sends them out to 15 to 50 ft; cold water stacks them in 20 to 60 ft. Shoreline point is the standout, a point at roughly 23 ft, rated good for spring atlantic herring. Plan around early morning and the evening in the warm months. A herring feather rig or a small silver jig covers the summer program.

In spring, whiting run shallow here, mostly 15 to 55 ft. Summer pushes them deeper, 20 to 70 ft, and winter fish settle into 15 to 70 ft. Time it for early morning. You won't need more than a small vertical jig most summer days.

Spring european flounder on Youghal Bay - Harbour hold shallow, usually 5 to 25 ft. They move out to 6 to 35 ft in summer and finish the year down in 15 to 50 ft. Put Feeding flat first on the milk run — a feeding flat near 31 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a bottom jig with spinner blade.

The complete Marine Institute Fishing Ports layer returned no port point inside this operational section. DepthScout does not substitute a nearby road, beach or community slipway as verified public fishing access; confirm legal access, parking, tides and local restrictions before visiting.
Private land and private launches need the owner's permission — please ask first.
Season dates, license requirements, and size and bag limits for Ireland waters are set by the Inland Fisheries Ireland (current sea-angling regulations) — and special regulations can apply to Youghal Bay - Harbour specifically, so confirm the current rules before you fish. Check the current national and water-specific rules before every trip, including bass measures, the 2026 recreational pollack controls, salmon and sea-trout licences and river-specific status, protected areas, harbour directions, private land and local signs. A mapped fishing port or measured seabed feature is not permission to fish, park, launch or enter a working harbour.

Youghal Bay - Harbour is about 255 ft (78 m) deep at its deepest point. The depth chart comes from INFOMAR (Geological Survey Ireland and Marine Institute) bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Official coastal monitoring from Marine Institute and Inland Fisheries Ireland informs the european seabass, atlantic mackerel, atlantic herring, whiting, european flounder, european plaice, common sole, thornback ray, brill, thick-lipped grey mullet, garfish, atlantic cod roster for Youghal Bay - Harbour. The mixed roster combines exact-water records where available with habitat-filtered regional evidence; not every species is documented at this exact water, and it is not a promise of equal abundance or a catch on a particular trip.
Feeding flat is the top-rated area: a feeding flat in about 31 ft of water that rates prime for european flounder in summer. Every other rated spot, per species and season, is on the map above.
For european seabass, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Youghal Bay - Harbour is regulated by the Inland Fisheries Ireland (current sea-angling regulations). Check the official Ireland regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
