81,071-acre Alabaster Coast. South West 1 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 1 angler-scale survey window. The water tops out around 112 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. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 81,183 acres of water rimmed by 46.1 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. About 1% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 13.5 mi of water from one end to the other, 11.8 mi at the beam. The nearest mapped water is Alabaster Coast - South West 2, 10 mi to the east.
Alabaster Coast — South West 1, France : carte SHOM officielle jusqu’à 34 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.

Start shallow in spring: european seabass sit in 3 to 25 ft that time of year. Summer pushes them deeper, 2 to 30 ft, and winter fish settle into 10 to 55 ft. The spot to know is Shoreline point, a point in about 18 ft of water that rates good for european seabass in fall. Warm-month bites cluster around early morning and the evening. Throw a surface lure or a paddle-tail soft plastic until the fish tell you otherwise.
| 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 | SHOM-grid channel edge (56 ft) | Slow soft-plastic shad, Suspending minnow |
Come spring, look for atlantic mackerel tight to the bank in 5 to 45 ft. Expect a summer slide to 15 to 80 ft, then a winter hold in 28 to 112 ft. Start at SHOM-grid current seam. It's a current seam holding about 45 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A feather rig or a small vertical jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | SHOM-grid current seam (45 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Sharp break (50 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | SHOM-grid current seam (45 ft) | Compact silver jig, Sparse feather rig |
| Winter | 28 to 112 ft | midday | Deepest basin (112 ft) | Small deep jig |
Start shallow in spring: european plaice sit in 8 to 35 ft that time of year. Warm water sends them out to 6 to 40 ft; cold water stacks them in 25 to 80 ft. Top water on the chart: SHOM-grid flat, a feeding flat in the 11 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a light spooned bottom rig or a beaded trace until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | SHOM-grid flat (11 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | SHOM-grid flat (11 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | SHOM-grid channel edge (56 ft) | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | SHOM-grid channel edge (56 ft) |
Early season common sole use the shallows, holding in 6 to 30 ft. Even in summer they hold at 3 to 30 ft; winter keeps them in 20 to 70 ft. The chart's best answer is SHOM-grid flat — feeding flat, 11 ft, prime for spring. Best bite is the evening. Tie on a light rolling-lead rig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 30 ft | dusk | SHOM-grid flat (11 ft) | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | SHOM-grid flat (11 ft) | Light rolling-lead rig |
| Fall | 8 to 40 ft | dusk | SHOM-grid flat (11 ft) | Compact bottom jig |
| Winter | 20 to 70 ft | night | SHOM-grid channel edge (56 ft) |
Come spring, look for european flounder tight to the bank in 5 to 25 ft. Expect a summer slide to 6 to 35 ft, then a winter hold in 15 to 50 ft. Start at SHOM-grid flat. It's a feeding flat holding about 11 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bottom jig with spinner blade is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | SHOM-grid flat (11 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | SHOM-grid flat (11 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | SHOM-grid flat (11 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Sharp break (50 ft) | Small bottom jig |
Start shallow in spring: whiting sit in 15 to 55 ft that time of year. Warm water sends them out to 20 to 70 ft; cold water stacks them in 15 to 70 ft. Top water on the chart: SHOM-grid channel edge, a channel edge in the 56 ft range, prime in fall. Fish it in early morning and you'll meet the bite. Throw a small vertical jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 55 ft | dawn & dusk | SHOM-grid channel edge (56 ft) | Small silver jig, Two-hook feather rig |
| Summer | 20 to 70 ft | dawn | SHOM-grid channel edge (56 ft) | Small vertical jig |
| Fall | 10 to 60 ft | dusk | SHOM-grid channel edge (56 ft) | Small silver jig, Sparse feather rig |
| Winter | 15 to 70 ft | dusk | SHOM-grid channel edge (56 ft) | Compact vertical jig |

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 1 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 1 is about 112 ft (34 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.
