21,575-acre Landes Coast. South 3 Central 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 exposed Landes coast south of Arcachon, with surf bars, deep beach troughs and river-mouth transitions. This page covers the south 3 central angler-scale survey window. The water tops out around 102 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. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 21,590 acres of water rimmed by 38.7 miles of bank. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. About 13% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 17.5 mi of water from one end to the other, 3.7 mi at the beam. For a second option, Landes Coast - South 3 West lies 7 mi west.

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.

The spring pattern is a shallow one: european seabass in 3 to 25 ft. As the season builds they drop to 2 to 30 ft, wintering in 10 to 55 ft. Top water on the chart: SHOM-grid current seam, a current seam in the 41 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a surface lure or a paddle-tail soft plastic gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Shoreline point (5 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Shoreline point (5 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | SHOM-grid current seam (41 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | SHOM-grid channel edge (51 ft) | Slow soft-plastic shad, Suspending minnow |
When the water first warms, atlantic mackerel slide up into 5 to 45 ft. By summer they slide out to 15 to 80 ft, and by winter most fish are in 26 to 102 ft. If you only fish one area, make it SHOM-grid current seam: a current seam around 41 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a feather rig or a small vertical jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | SHOM-grid current seam (41 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Sharp break (55 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | SHOM-grid current seam (41 ft) | Compact silver jig, Sparse feather rig |
| Winter | 26 to 102 ft | midday | Deepest basin (101 ft) | Small deep jig |
In spring, garfish run shallow here, mostly 1 to 15 ft. Summer pushes them deeper, 2 to 20 ft, and winter fish settle into 20 to 60 ft. Shoreline point is the standout, a point at roughly 5 ft, rated prime for spring garfish. Time it for early morning and the evening. You won't need more than a slim casting spoon or a surface-skipping fly most summer days.
| 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 | open water | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | SHOM-grid current seam (41 ft) |
Spring common sole on Landes Coast - South 3 Central hold shallow, usually 6 to 30 ft. Depth-wise the year is flat: 3 to 30 ft in summer, 20 to 70 ft once it turns cold. Put SHOM-grid flat first on the milk run — a feeding flat near 10 ft that grades prime for spring. The feeding windows run the evening. The summer box starts with a light rolling-lead rig.

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 Landes Coast - South 3 Central 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.
