34,543-acre Kinsale Harbour. Inner 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 inner trip-scale survey reach of Kinsale Harbour, retaining only official survey-backed seabed cells that pass the Ireland release gates. The water tops out around 227 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. What the data behind the map says about each species, season by season:
The outline encloses 34,513 acres, worked by 56.8 miles of shoreline. The 2.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 5% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 11.9 mi of water from one end to the other, 11.3 mi at the beam. Kinsale Harbour - Outer sits 7 mi west — the closest neighbouring chart.
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 Kinsale Harbour - Inner 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, 18 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 (18 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Shoreline point (18 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (18 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 16 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 (18 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Sharp break (16 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Sharp break (16 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Sharp break (16 ft) | Small deep jig |
Spring atlantic herring on Kinsale Harbour - Inner 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, 16 ft, good for summer. 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 (18 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Sharp break (16 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Sharp break (16 ft) | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | Sharp break (16 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 INFOMAR measured flat, a prime-rated feeding flat around 27 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 | INFOMAR measured flat (27 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | INFOMAR measured flat (27 ft) | Bottom jig with spinner blade |

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 INFOMAR measured flat. It's a feeding flat holding about 27 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 | INFOMAR measured flat (27 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | INFOMAR measured flat (27 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | INFOMAR measured flat (27 ft) | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | open water |

Kinsale Harbour - Inner is about 227 ft (69 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 Kinsale Harbour - Inner. 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.
INFOMAR measured flat is the top-rated area: a feeding flat in about 27 ft of water that rates prime for european flounder in summer. Open the map above to see every rated spot for each 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.
