8,965-acre Golfe Normand-Breton. 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 Normandy-Brittany Gulf and Mont-Saint-Michel approaches, where broad banks and channels require trip-scale sections. This page covers the north west 4 angler-scale survey window. The water tops out around 30 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.
Golfe Normand-Breton - North West 4 maps at 8,965 acres behind 19.6 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. Roughly 77% of the water is 15 ft or less, the band where the food chain lives. Figure 5.3 mi of water from one end to the other, 4 mi at the beam. Golfe Normand-Breton - South West 3 sits 7 mi southwest — the closest neighbouring chart.

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. By summer they slide out to 2 to 30 ft, and by winter most fish are in 5 to 30 ft. If you only fish one area, make it SHOM-grid current seam: a current seam around 12 ft that scores prime in summer. In summer the feeding windows fall in 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 30 ft | dawn & dusk | SHOM-grid current seam (12 ft) | Slim metal lure, Minnow plug |
| Winter | 5 to 30 ft | midday | Deepest basin (30 ft) | Slow soft-plastic shad, Suspending minnow |
In spring, common sole run shallow here, mostly 6 to 30 ft. Summer keeps them at 3 to 30 ft, and they winter in 9 to 30 ft. Spring common sole concentrate at Feeding flat, a prime-rated feeding flat around 13 ft. Fish it in the evening and you'll meet the bite. 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 (13 ft) | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | Feeding flat (13 ft) | Light rolling-lead rig |
| Fall | 6 to 30 ft | dusk | SHOM-grid channel edge (15 ft) | Compact bottom jig |
| Winter | 9 to 30 ft | night | Deepest basin (30 ft) |
The spring pattern is a shallow one: european flounder in 5 to 25 ft. As the season builds they drop to 5 to 30 ft, wintering in 9 to 30 ft. Top water on the chart: Feeding flat, a feeding flat in the 13 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a bottom jig with spinner blade gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | Feeding flat (13 ft) | Small bucktail dragged on bottom |
| Summer | 5 to 30 ft | dawn & dusk | Feeding flat (13 ft) | Bottom jig with spinner blade |
| Fall | 6 to 30 ft | dusk | Sharp break (15 ft) | Compact bottom jig |
| Winter | 9 to 30 ft | midday | Deepest basin (30 ft) | Small bottom jig |
Early season european plaice use the shallows, holding in 7 to 30 ft. Even in summer they hold at 5 to 30 ft; winter keeps them in 9 to 30 ft. Put Feeding flat first on the milk run — a feeding flat near 13 ft that grades prime for spring. In summer the feeding windows fall in 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 | 7 to 30 ft | dusk | Feeding flat (13 ft) | Beaded flowing trace |
| Summer | 5 to 30 ft | dawn & dusk | Feeding flat (13 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 6 to 30 ft | dusk | SHOM-grid channel edge (15 ft) | Beaded bottom trace |
| Winter | 9 to 30 ft | midday | Deepest basin (30 ft) |
Early season whiting use the shallows, holding in 8 to 30 ft. Even in summer they hold at 9 to 30 ft; winter keeps them in 6 to 30 ft. Put SHOM-grid channel edge first on the milk run — a channel edge near 15 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a small vertical jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 30 ft | dawn & dusk | SHOM-grid channel edge (15 ft) | Small silver jig, Two-hook feather rig |
| Summer | 9 to 30 ft | dawn | Deepest basin (30 ft) | Small vertical jig |
| Fall | 5 to 30 ft | dusk | SHOM-grid channel edge (15 ft) | Small silver jig, Sparse feather rig |
| Winter | 6 to 30 ft | dusk | Deepest basin (30 ft) | Compact vertical jig |
When the water first warms, garfish slide up into 1 to 15 ft. Summer is a 2 to 20 ft game here, winter a 9 to 30 ft one. Start at Shoreline point. It's a point holding about 5 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a slim casting spoon or a surface-skipping fly rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | Shoreline point (5 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | Shoreline point (5 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | SHOM-grid current seam (12 ft) | Weighted slim spoon, Small silver jig |
| Winter | 9 to 30 ft | midday | Deepest basin (30 ft) |

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 Golfe Normand-Breton - 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.

Golfe Normand-Breton - North West 4 is about 30 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.
Official coastal monitoring from Ifremer CGFS and coastal estuary monitoring regional survey evidence informs the european seabass, common sole, european flounder, european plaice, whiting, garfish, atlantic mackerel, thick-lipped grey mullet, flathead grey mullet, brill, thornback ray, european eel, atlantic salmon roster for Golfe Normand-Breton - North West 4. 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.
SHOM-grid current seam is the top-rated area: a current seam in about 12 ft of water that rates prime for european seabass in summer. Every other rated spot, per species and season, is on the map above.
