45,206-acre Youghal Bay. Outer 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 outer 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 235 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. Species by species, here's what the data says the year looks like.
Youghal Bay - Outer maps at 45,155 acres behind 38.8 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. The shallow band under 15 ft claims about 3% of the surface — that's where the groceries are. Figure 13.4 mi of water from one end to the other, 9.8 mi at the beam. If the bite dies, Cork Harbour - East is 3 mi to the southwest.
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 european seabass on Youghal Bay - Outer hold shallow, usually 3 to 25 ft. By summer they slide out to 2 to 30 ft, and by winter most fish are in 10 to 55 ft. The chart's best answer is Shoreline point — point, 5 ft, good for fall. Prime time lands in early morning and the evening. The summer box starts with a surface lure or a paddle-tail soft plastic.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Shoreline point (5 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Shoreline point (5 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (5 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
Spring puts atlantic mackerel in skinny water — 5 to 45 ft is the zone. As the season builds they drop to 15 to 80 ft, wintering in 30 to 120 ft. Summer atlantic mackerel concentrate at Sharp break, a good-rated drop-off around 66 ft. Warm-month bites cluster around early morning and the evening. A feather rig or a small vertical jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Shoreline point (5 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Sharp break (66 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Sharp break (66 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Sharp break (66 ft) | Small deep jig |
Spring atlantic herring on Youghal Bay - Outer hold shallow, usually 5 to 25 ft. By summer they slide out to 15 to 50 ft, and by winter most fish are in 20 to 60 ft. The chart's best answer is Sharp break — drop-off, 66 ft, good for winter. Prime time lands in early morning and the evening. The summer box starts with a herring feather rig or a small silver jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Shoreline point (5 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | open water | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | open water | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | Sharp break (66 ft) | Small silver jig, Sparse feather rig |
Come spring, look for whiting tight to the bank in 15 to 55 ft. Expect a summer slide to 20 to 70 ft, then a winter hold in 15 to 70 ft. Prime time lands in early morning. A small vertical jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 55 ft | dawn & dusk | open water | Small silver jig, Two-hook feather rig |
| Summer | 20 to 70 ft | dawn | open water | Small vertical jig |
| Fall | 10 to 60 ft | dusk | open water | Small silver jig, Sparse feather rig |
| Winter | 15 to 70 ft | dusk | open water | Compact vertical jig |
Spring puts european flounder in skinny water — 5 to 25 ft is the zone. As the season builds they drop to 6 to 35 ft, wintering in 15 to 50 ft. Summer european flounder concentrate at Feeding flat, a prime-rated feeding flat around 32 ft. Warm-month bites cluster around early morning and the evening. A bottom jig with spinner blade covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | Feeding flat (32 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Feeding flat (32 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Feeding flat (32 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Feeding flat (32 ft) | Small bottom jig |
Come spring, look for european plaice tight to the bank in 8 to 35 ft. Expect a summer slide to 6 to 40 ft, then a winter hold in 25 to 80 ft. Start at Feeding flat. It's a feeding flat holding about 32 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A light spooned bottom rig or a beaded trace is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | Feeding flat (32 ft) | Beaded flowing trace |

| Fall | 10 to 50 ft | dusk | Feeding flat (32 ft) | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | open water |

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 - Outer 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 - Outer is about 235 ft (72 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 - Outer. 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 32 ft of water that rates prime for european flounder in summer. The map above holds the full rated-spot list for every species and season.
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.
