98,873-acre Landes Coast. South 4 West 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 4 west angler-scale survey window. The water tops out around 304 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.
The drawn water covers 98,818 acres wrapped in 54.2 miles of bank. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Roughly 0% of the water is 15 ft or less, the band where the food chain lives. Figure 17.4 mi of water from one end to the other, 10.5 mi at the beam. If the bite dies, Landes Coast - South 4 Central is 8 mi to the east.
Landes Coast — South 4 West, France : carte SHOM officielle jusqu’à 93 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.

Early season european seabass use the shallows, holding in 3 to 25 ft. Summer is a 2 to 30 ft game here, winter a 10 to 55 ft one. Best bite is early morning and the evening. Tie on a surface lure or a paddle-tail soft plastic and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | open water | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | open water | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | open water | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
In spring, atlantic mackerel run shallow here, mostly 5 to 45 ft. Midsummer fish sit out in 15 to 80 ft before dropping to 30 to 120 ft for winter. Winter atlantic mackerel concentrate at SHOM-grid current seam, a good-rated current seam around 122 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a feather rig or a small vertical jig most summer days.

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 Landes Coast - South 4 West 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.

Landes Coast - South 4 West is about 304 ft (93 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.
