11,648-acre Alabaster Coast. South West 3 France saltwater fishing map with official SHOM 100 m bathymetry, source-qualified fishing spots, official regional fish evidence, seasonal forage guidance, public shore-use context and current-rule links. The chalk-cliff coast from Le Tréport through Dieppe toward Fécamp, with exposed shingle, rock and harbor approaches. This page covers the south west 3 angler-scale survey window. The water tops out around 76 ft. The depth chart comes from Shom (Service hydrographique et océanographique de la Marine) 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.
On the chart, Alabaster Coast - South West 3 draws 11,650 acres inside 32.4 miles of shoreline. Index 2.1 on the shoreline: a few honest points and pockets, nothing labyrinthine. 20% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 11.1 mi long by 3.2 mi wide at the broadest reach. Closest neighbour on DepthScout: Alabaster Coast - North West 3, 7 mi north of here.
Alabaster Coast — South West 3, France : carte SHOM officielle jusqu’à 23 m; spots pour bar commun, maquereau commun. Pour préparer la pêche, jamais pour naviguer. Les profondeurs et les points de structure proviennent de la grille bathymétrique officielle du Shom. Les données servent à préparer la pêche et ne doivent jamais être utilisées pour la navigation.
Regional occurrence supports a search target, not equal abundance, child-specific catch rate, retention permission or a promised catch. Current national, EU, regional, protected-area and species rules always control. 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.

In spring, european seabass run shallow here, mostly 3 to 25 ft. Midsummer fish sit out in 2 to 30 ft before dropping to 10 to 55 ft for winter. Summer european seabass concentrate at SHOM-grid current seam, a prime-rated current seam around 30 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a surface lure or a paddle-tail soft plastic most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Shoreline point (6 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | SHOM-grid current seam (30 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | SHOM-grid current seam (30 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | SHOM-grid channel edge (38 ft) | Slow soft-plastic shad, Suspending minnow |
Early season atlantic mackerel use the shallows, holding in 5 to 45 ft. Summer is a 14 to 76 ft game here, winter a 19 to 76 ft one. The chart's best answer is Deepest basin — deep basin, 75 ft, prime for summer. Best bite is early morning and the evening. Tie on a feather rig or a small vertical jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | SHOM-grid current seam (30 ft) | Mackerel feather rig, Small silver jig |
| Summer | 14 to 76 ft | dawn & dusk | Deepest basin (75 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | SHOM-grid current seam (30 ft) | Compact silver jig, Sparse feather rig |
| Winter | 19 to 76 ft | midday | Deepest basin (75 ft) | Small deep jig |
Spring puts european plaice in skinny water — 8 to 35 ft is the zone. As the season builds they drop to 6 to 40 ft, wintering in 23 to 76 ft. Spring european plaice concentrate at SHOM-grid flat, a prime-rated feeding flat around 8 ft. Warm-month bites cluster around early morning and the evening. A light spooned bottom rig or a beaded trace covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | SHOM-grid flat (8 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | SHOM-grid flat (8 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | SHOM-grid channel edge (38 ft) | Beaded bottom trace |
| Winter | 23 to 76 ft | midday | Deepest basin (75 ft) |
When the water first warms, common sole slide up into 6 to 30 ft. There's no big seasonal slide here — summer means 3 to 30 ft, winter 20 to 70 ft. If you only fish one area, make it SHOM-grid flat: a feeding flat around 8 ft that scores prime in spring. In summer the feeding windows fall in the evening. Keep a light rolling-lead rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 30 ft | dusk | SHOM-grid flat (8 ft) | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | SHOM-grid flat (8 ft) | Light rolling-lead rig |
| Fall | 8 to 40 ft | dusk | SHOM-grid channel edge (38 ft) | Compact bottom jig |
| Winter | 20 to 70 ft | night | Deepest basin (75 ft) |
Early season european flounder use the shallows, holding in 5 to 25 ft. Summer is a 6 to 35 ft game here, winter a 15 to 50 ft one. The chart's best answer is SHOM-grid flat — feeding flat, 8 ft, prime for spring. Best bite is early morning and the evening. Tie on a bottom jig with spinner blade and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | SHOM-grid flat (8 ft) | Small bucktail dragged on bottom |

| Winter | 15 to 50 ft | midday | Sharp break (41 ft) | Small bottom jig |
Spring puts whiting in skinny water — 15 to 55 ft is the zone. As the season builds they drop to 20 to 70 ft, wintering in 15 to 70 ft. Spring whiting concentrate at SHOM-grid channel edge, a prime-rated channel edge around 38 ft. Warm-month bites cluster around early morning. A small vertical jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 55 ft | dawn & dusk | SHOM-grid channel edge (38 ft) | Small silver jig, Two-hook feather rig |

Access data: European Environment Agency — 2025 Bathing Water Directive Sites (France). Confirm conditions and fees locally before you launch.
Season dates, license requirements, and size and bag limits for France waters are set by the Légifrance (current French recreational sea-fishing minimum sizes) — and special regulations can apply to Alabaster Coast - South West 3 specifically, so confirm the current rules before you fish. French recreational sea-fishing rules combine current national and European species measures with façade, prefectural, marine-protected-area, harbour and local access controls. Check live minimum sizes, quotas, seasonal or method closures, marking requirements and any no-take zone before every trip. A SHOM contour, fishing-spot marker or designated bathing-water lead is planning context only and never permission to fish, retain a catch, park, launch or enter restricted shore or port property.

Alabaster Coast - South West 3 is about 76 ft (23 m) deep at its deepest point. The depth chart comes from Shom (Service hydrographique et océanographique de la Marine) bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
