28,800-acre Cwb-Ii-4. Sector 05 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 312 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. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 28,795 acres of water rimmed by 28.2 miles of bank. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 0% of this chart. Call it 9.8 mi long by 6.3 mi wide at the broadest reach. Closest neighbour on DepthScout: Cwb-Ii-4 - Sector 06, 3 mi east of here.
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.

The spring pattern is a shallow one: european seabass in 3 to 25 ft. Midsummer fish sit out in 2 to 30 ft before dropping to 10 to 55 ft for winter. Plan around early morning and the evening in the warm months. 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 | 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 |
When the water first warms, gilthead seabream slide up into 3 to 35 ft. Summer is a 2 to 45 ft game here, winter a 20 to 100 ft one. The feeding windows run early morning and the evening.

Spring meagre on Cwb-Ii-4 - Sector 05 hold shallow, usually 12 to 80 ft. They move out to 8 to 100 ft in summer and finish the year down in 40 to 180 ft. Put Sharp break first on the milk run — a drop-off near 143 ft that grades good for winter. The feeding windows run the evening.

When the water first warms, atlantic mackerel slide up into 5 to 45 ft. Summer is a 15 to 80 ft game here, winter a 30 to 120 ft one. Start at Sharp break. It's a drop-off holding about 68 ft of water and rates good come summer. The feeding windows run 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 | open water | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Sharp break (68 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Sharp break (68 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Sharp break (68 ft) | Small deep jig |
Start shallow in spring: atlantic bonito sit in 15 to 100 ft that time of year. They don't go far with the seasons — 5 to 90 ft covers summer, 50 to 220 ft covers winter. The spot to know is Sharp break, a drop-off in about 68 ft of water that rates good for atlantic bonito in fall. Warm-month bites cluster around early morning and the evening.
| Season | Depth | Best window | Start at | Go-to baits |

In spring, garfish run shallow here, mostly 1 to 15 ft. Midsummer fish sit out in 2 to 20 ft before dropping to 20 to 60 ft for winter. Fish it in early morning and the evening and you'll meet the bite. 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 | open water | Slim silver spoon, Small inline spinner |

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-4 - Sector 05 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-4 - Sector 05 is about 312 ft (95 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-4 - Sector 05. 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.
Sharp break is the top-rated area: a drop-off in about 68 ft of water that rates good for atlantic mackerel in summer. 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-4 - Sector 05 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.
