85,826-acre Alabaster Coast. North West 2 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 2 angler-scale survey window. The water tops out around 131 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. Species by species, here's what the data says the year looks like.
The outline encloses 85,796 acres, worked by 46.3 miles of shoreline. The basin is a simple one (shoreline index 1.1) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 0% of this chart. The basin spans about 15.3 mi end to end and 14.4 mi across at its widest. Its nearest charted neighbour, Alabaster Coast - South West 2, is 10 mi to the south.
Alabaster Coast — North West 2, France : carte SHOM officielle jusqu’à 40 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.

Spring european seabass on Alabaster Coast - North West 2 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. 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 | open water | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | open water | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | open water | 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. Winter atlantic mackerel concentrate at Deepest basin, a good-rated deep basin around 127 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 | open water | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | SHOM-grid current seam (75 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | SHOM-grid current seam (75 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Deepest basin (127 ft) | Small deep 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 SHOM-grid channel edge. It's a channel edge holding about 74 ft of water and rates good come winter. Prime time lands in early morning and the evening. A light spooned bottom rig or a beaded trace is the honest summer answer here.

| Fall | 10 to 50 ft | dusk | open water | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | SHOM-grid channel edge (74 ft) |
The spring pattern is a shallow one: common sole in 6 to 30 ft. The depth story barely changes: 3 to 30 ft through summer, 20 to 70 ft in winter. The spot to know is SHOM-grid channel edge, a channel edge in about 74 ft of water that rates good for common sole in winter. Plan around the evening in the warm months. Summer baits: a light rolling-lead rig gets it done.

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. Warm-month bites cluster around early morning and the evening. A bottom jig with spinner blade covers the summer program.

No official 2025 EEA designated bathing-water point matched within 400 metres of this SHOM-grid shoreline. This is an access-evidence gap, not a statement that public fishing access does not exist. Verify local fishing rights, land ownership, posted restrictions, protected areas, tidal and surf safety, and municipal permission before entry.
Private land and private launches need the owner's permission — please ask first.
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 2 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.
