77,093-acre Alabaster Coast. North West 4 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 north west 4 angler-scale survey window. The water tops out around 84 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. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 77,203 acres wrapped in 48 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. Roughly 3% of the water is 15 ft or less, the band where the food chain lives. Figure 12.5 mi of water from one end to the other, 10.9 mi at the beam. Alabaster Coast - North West 5 sits 10 mi east — the closest neighbouring chart.
Alabaster Coast — North West 4, France : carte SHOM officielle jusqu’à 26 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.

When the water first warms, european seabass slide up into 3 to 25 ft. Summer is a 2 to 30 ft game here, winter a 10 to 55 ft one. Start at SHOM-grid current seam. It's a current seam holding about 34 ft of water and rates prime come fall. The feeding windows run early morning and the evening. Keep a surface lure or a paddle-tail soft plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Shoreline point (11 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | SHOM-grid current seam (34 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | SHOM-grid current seam (34 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | SHOM-grid channel edge (42 ft) | Slow soft-plastic shad, Suspending minnow |
The spring pattern is a shallow one: atlantic mackerel in 5 to 45 ft. Midsummer fish sit out in 15 to 80 ft before dropping to 21 to 84 ft for winter. The spot to know is SHOM-grid current seam, a current seam in about 34 ft of water that rates prime for atlantic mackerel in fall. Plan around early morning and the evening in the warm months. Summer baits: a feather rig or a small vertical jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | SHOM-grid current seam (34 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Deepest basin (84 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | SHOM-grid current seam (34 ft) | Compact silver jig, Sparse feather rig |
| Winter | 21 to 84 ft | midday | Deepest basin (84 ft) | Small deep jig |
Early season european plaice use the shallows, holding in 8 to 35 ft. Summer is a 6 to 40 ft game here, winter a 25 to 80 ft one. The chart's best answer is Feeding flat — feeding flat, 29 ft, prime for spring. Best bite is early morning and the evening. Tie on a light spooned bottom rig or a beaded trace and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | Feeding flat (29 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | Feeding flat (29 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | SHOM-grid channel edge (42 ft) | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | Deepest basin (84 ft) |
In spring, common sole run shallow here, mostly 6 to 30 ft. Summer keeps them at 3 to 30 ft, and they winter in 20 to 70 ft. Feeding flat is the standout, a feeding flat at roughly 29 ft, rated prime for spring common sole. Time it for the evening. You won't need more than a light rolling-lead rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 30 ft | dusk | Feeding flat (29 ft) | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | Feeding flat (29 ft) | Light rolling-lead rig |
| Fall | 8 to 40 ft | dusk | SHOM-grid channel edge (42 ft) | Compact bottom jig |
| Winter | 20 to 70 ft | night | SHOM-grid channel edge (42 ft) |
The spring pattern is a shallow one: european flounder in 5 to 25 ft. Midsummer fish sit out in 6 to 35 ft before dropping to 15 to 50 ft for winter. The spot to know is Feeding flat, a feeding flat in about 29 ft of water that rates prime for european flounder in summer. Plan around early morning and the evening in the warm months. Summer baits: a bottom jig with spinner blade gets it done.

Early season whiting use the shallows, holding in 15 to 55 ft. Summer is a 20 to 70 ft game here, winter a 15 to 70 ft one. The chart's best answer is SHOM-grid channel edge — channel edge, 42 ft, prime for spring. Best bite is early morning. Tie on a small vertical jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |

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 - North West 4 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.
