26,969-acre Golfe Normand-Breton. 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 Normandy-Brittany Gulf and Mont-Saint-Michel approaches, where broad banks and channels require trip-scale sections. This page covers the south west 1 angler-scale survey window. The water tops out around 90 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.
On the chart, Golfe Normand-Breton - South West 1 draws 26,979 acres inside 38.5 miles of shoreline. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. Roughly 14% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 11.1 mi, about 7.2 mi across. The nearest mapped water is Saint-Malo and Rance - North West, 7 mi to the east.
Golfe Normand-Breton — South West 1, France : carte SHOM officielle jusqu’à 27 m; spots pour bar commun, sole commune. 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. Warm water sends them out to 2 to 30 ft; cold water stacks them in 10 to 55 ft. Top water on the chart: SHOM-grid current seam, a current seam in the 36 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. 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 (3 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | SHOM-grid current seam (36 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | SHOM-grid current seam (36 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | SHOM-grid channel edge (45 ft) | Slow soft-plastic shad, Suspending minnow |
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. Put Feeding flat first on the milk run — a feeding flat near 36 ft that grades good for fall. In summer the feeding windows fall in 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 | Feeding flat (36 ft) | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | Feeding flat (36 ft) | Light rolling-lead rig |
| Fall | 8 to 40 ft | dusk | Feeding flat (36 ft) | Compact bottom jig |
| Winter | 20 to 70 ft | night | SHOM-grid channel edge (45 ft) |
Come spring, look for european flounder tight to the bank in 5 to 25 ft. They move out to 6 to 35 ft in summer and finish the year down in 15 to 50 ft. If you only fish one area, make it Feeding flat: a feeding flat around 36 ft that scores prime in summer. Best bite is 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 shoal (16 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Feeding flat (36 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Feeding flat (36 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | SHOM-grid channel edge (45 ft) | Small bottom jig |
Start shallow in spring: european plaice sit in 8 to 35 ft that time of year. Summer pushes them deeper, 6 to 40 ft, and winter fish settle into 25 to 80 ft. The spot to know is Feeding flat, a feeding flat in about 36 ft of water that rates prime for european plaice in summer. Warm-month bites cluster around early morning and the evening. 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 | Feeding flat (36 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | Feeding flat (36 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | SHOM-grid channel edge (45 ft) | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | Deepest basin (85 ft) |
Start shallow in spring: whiting sit in 15 to 55 ft that time of year. Summer pushes them deeper, 20 to 70 ft, and winter fish settle into 15 to 70 ft. The spot to know is SHOM-grid channel edge, a channel edge in about 45 ft of water that rates prime for whiting in spring. Warm-month bites cluster around early morning. 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 (45 ft) | Small silver jig, Two-hook feather rig |
| Summer | 20 to 70 ft | dawn | SHOM-grid channel edge (45 ft) | Small vertical jig |
| Fall | 10 to 60 ft | dusk | SHOM-grid channel edge (45 ft) | Small silver jig, Sparse feather rig |
| Winter | 15 to 70 ft | dusk | SHOM-grid channel edge (45 ft) | Compact vertical jig |
Spring puts garfish in skinny water — 1 to 15 ft is the zone. Warm water sends them out to 2 to 20 ft; cold water stacks them in 20 to 60 ft. Shoreline point is the standout, a point at roughly 3 ft, rated prime for spring garfish. Plan around early morning and the evening in the warm months. A slim casting spoon or a surface-skipping fly covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | Shoreline point (3 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | Shoreline point (3 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | SHOM-grid current seam (36 ft) | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | SHOM-grid current seam (36 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 - 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.

Golfe Normand-Breton - South West 1 is about 90 ft (27 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 - South West 1. 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 36 ft of water that rates prime for european seabass in fall. Every other rated spot, per species and season, is on the map above.
