3,989-acre West Cotentin Coast. South 3 East 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 west Cotentin shore from Carteret to Granville, with islands, rock, sand banks and macrotidal channels. This page covers the south 3 east angler-scale survey window. The water tops out around 31 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 the data behind the map says about each species, season by season:
The drawn water covers 3,989 acres wrapped in 14 miles of bank. A middling shoreline index (1.6) gives it some bays to work without being a maze. 48% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 5.2 mi long by 2.6 mi wide at the broadest reach. If the bite dies, West Cotentin Coast - South 3 Central is 7 mi to the northwest.
West Cotentin Coast — South 3 East, France : carte SHOM officielle jusqu’à 9 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 6 to 31 ft one. Start at SHOM-grid current seam. It's a current seam holding about 12 ft of water and rates prime come summer. 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 | SHOM-grid current seam (12 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | SHOM-grid current seam (12 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 3 to 31 ft | dawn & dusk | SHOM-grid current seam (12 ft) | Slim metal lure, Minnow plug |
| Winter | 6 to 31 ft | midday | Deepest basin (29 ft) | Slow soft-plastic shad, Suspending minnow |
The spring pattern is a shallow one: atlantic mackerel in 3 to 31 ft. The depth story barely changes: 6 to 31 ft through summer, 8 to 31 ft in winter. The spot to know is Deepest basin, a deep basin in about 29 ft of water that rates prime for atlantic mackerel in summer. 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 | 3 to 31 ft | dawn & dusk | SHOM-grid current seam (12 ft) | Mackerel feather rig, Small silver jig |
| Summer | 6 to 31 ft | dawn & dusk | Deepest basin (29 ft) | Feather rig, Small vertical jig |
| Fall | 5 to 31 ft | dawn & dusk | SHOM-grid current seam (12 ft) | Compact silver jig, Sparse feather rig |
| Winter | 8 to 31 ft | midday | Deepest basin (29 ft) | Small deep jig |
Start shallow in spring: atlantic pollock sit in 2 to 31 ft that time of year. They don't go far with the seasons — 2 to 31 ft covers summer, 5 to 31 ft covers winter. The spot to know is Shoreline point, a point in about 5 ft of water that rates prime for atlantic pollock in summer. Warm-month bites cluster around early morning and the evening. Throw a surface plug or a baitfish swimbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 31 ft | dawn & dusk | Shoreline point (5 ft) | Sandeel-pattern lure, Soft-plastic shad |
| Summer | 2 to 31 ft | dawn & dusk | Shoreline point (5 ft) | Surface plug, Baitfish swimbait |
| Fall | 3 to 31 ft | dawn | Shoreline point (5 ft) | Metal jig, Minnow plug |
| Winter | 5 to 31 ft | midday | Sharp break (17 ft) | Slow metal jig, Weighted soft plastic |
When the water first warms, saithe (coalfish) slide up into 3 to 31 ft. There's no big seasonal slide here — summer means 3 to 31 ft, winter 4 to 31 ft. Start at SHOM-grid current seam. It's a current seam holding about 12 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a speed jig or a heavy paddletail rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 31 ft | dawn & dusk | SHOM-grid current seam (12 ft) | Slim metal jig, Paddletail |

| Winter | 4 to 31 ft | midday | Deepest basin (29 ft) | Heavy vertical jig |
Start shallow in spring: atlantic cod sit in 6 to 31 ft that time of year. They don't go far with the seasons — 8 to 31 ft covers summer, 7 to 31 ft covers winter. The spot to know is Deepest basin, a deep basin in about 29 ft of water that rates prime for atlantic cod in winter. Warm-month bites cluster around early morning. Throw a heavy metal jig or a large soft-plastic jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 31 ft | dawn | Sharp break (17 ft) | Diamond jig, Heavy bucktail |

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 West Cotentin Coast - South 3 East 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.

West Cotentin Coast - South 3 East is about 31 ft (9 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.

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.
