48,340-acre Cwb-Ii-3B. Sector 10 Portugal coastal fishing map with an exact official national water-body boundary, EMODnet 2024 CDI-audited Portuguese hydrographic and research-survey/composite DTM contours, source-assessed fishing spots, official regional fish evidence, seasonal forage guidance, public-access review and current-rule links. Official Portuguese WFD named coastal or transitional assessment water in Central Portugal Atlantic Coast. This child is clipped to the exact source polygon and a trip-scale ownership window. Coverage classes and uncertainty limits are disclosed; this is a fishing-planning chart, not a navigation chart or catch forecast. The water tops out around 389 ft. The depth chart comes from EMODnet, with national hydrographic source-reference audit 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.
The outline encloses 48,363 acres, worked by 39 miles of shoreline. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. 4% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 14.5 mi long by 9.3 mi wide at the broadest reach. Cwb-Ii-4 - Sector 02 sits 12 mi southwest — the closest neighbouring chart.
Occurrence evidence does not promise a catch or establish that retention is legal. Current seasons, closures, protected species, gear rules and local restrictions 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 10 to 55 ft one. Start at Shoreline point. It's a point holding about 10 ft of water and rates good come fall. 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 | Shoreline point (10 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Shoreline point (10 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (10 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
The spring pattern is a shallow one: gilthead seabream in 3 to 35 ft. Midsummer fish sit out in 2 to 45 ft before dropping to 20 to 100 ft for winter. Plan around early morning and the evening in the warm months.

Start shallow in spring: meagre sit in 12 to 80 ft that time of year. Summer pushes them deeper, 8 to 100 ft, and winter fish settle into 40 to 180 ft. The spot to know is Sharp break, a drop-off in about 55 ft of water that rates good for meagre in winter. Warm-month bites cluster around the evening.

The spring pattern is a shallow one: atlantic mackerel in 5 to 45 ft. Midsummer fish sit out in 15 to 80 ft before dropping to 30 to 120 ft for winter. The spot to know is Sharp break, a drop-off in about 55 ft of water that rates good 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 | 5 to 45 ft | dawn & dusk | Shoreline point (10 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 | Sharp break (55 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Sharp break (55 ft) | Small deep jig |
Spring atlantic bonito on Cwb-Ii-3B - Sector 10 hold shallow, usually 15 to 100 ft. Depth-wise the year is flat: 5 to 90 ft in summer, 50 to 220 ft once it turns cold. Put Shoreline point first on the milk run — a point near 61 ft that grades prime for summer. The feeding windows run early morning and the evening.
| Season | Depth | Best window | Start at | Go-to baits |

When the water first warms, garfish slide up into 1 to 15 ft. By summer they slide out to 2 to 20 ft, and by winter most fish are in 20 to 60 ft. If you only fish one area, make it Shoreline point: a point around 10 ft that scores prime in spring. In summer the feeding windows fall in 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 (10 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | Shoreline point (10 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | Shoreline point (10 ft) | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | Sharp break (55 ft) |
Cwb-Ii-3B - Sector 10 also holds common sole (3 to 30 ft in summer), thick-lipped grey mullet (1 to 18 ft in summer). Pick any of them on the map above for rated spots and bait picks.
17 pieces of structure are mapped here — Deepest basin, around 385 ft, is the deepest of them.
Portuguese Environment Agency official SNIAmb bathing-water review was reviewed, but no stable government record establishes a public fishing entrance, parking or launch for this exact mapped child. This is an access-evidence gap, not a claim that public access does not exist. Verify land ownership, port and harbour rules, protected areas, local signs, parking, safety, permits and fishing 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 Portugal waters are set by the Portuguese Directorate-General for Natural Resources, Safety and Maritime Services (recreational fishing) — and special regulations can apply to Cwb-Ii-3B - Sector 10 specifically, so confirm the current rules before you fish. Check Portugal's live DGRM, regional, port-authority and protected-area rules before every coastal trip. A current licence, RecFishing catch reporting, daily possession limits, minimum sizes, species closures, method limits, bathing-season restrictions, navigation-channel exclusions and local maritime notices may apply. Marine protected areas including Berlengas, Arrábida, the Southwest Alentejo and Vicentine Coast, Ria Formosa and other reserves impose additional zoned restrictions or authorizations. A WFD boundary, source-audited contour, fishing-spot marker or bathing-water record is planning context only and never grants fishing, retention, shore entry, parking, launching, port access or safe navigation permission.

Cwb-Ii-3B - Sector 10 is about 389 ft (119 m) deep at its deepest point. The depth chart comes from EMODnet, with national hydrographic source-reference audit bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Official coastal monitoring from Portugal national fisheries and coastal monitoring agencies informs the european seabass, gilthead seabream, meagre, atlantic mackerel, atlantic bonito, garfish, common sole, thick-lipped grey mullet roster for Cwb-Ii-3B - Sector 10. 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.
Shoreline point is the top-rated area: a point in about 10 ft of water that rates prime for garfish in spring. Every other rated spot, per species and season, is on the map above.
For european seabass, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Cwb-Ii-3B - Sector 10 is regulated by the Portuguese Directorate-General for Natural Resources, Safety and Maritime Services (recreational fishing). Check the official Portugal regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
