28,530-acre Cwb-Ii-3A. North 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 147 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 the data behind the map says about each species, season by season:
Cwb-Ii-3A - North maps at 28,521 acres behind 27.2 miles of shoreline. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. The shallow band under 15 ft claims about 4% of the surface — that's where the groceries are. The basin spans about 9.2 mi end to end and 8.8 mi across at its widest. Its nearest charted neighbour, Cwb-Ii-3A - North West, is 5 mi to the west.
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.

Come spring, look for european seabass tight to the bank in 3 to 25 ft. They move out to 2 to 30 ft in summer and finish the year down in 10 to 55 ft. If you only fish one area, make it Shoreline point: a point around 6 ft that scores good in fall. Best bite is early morning and the evening. A surface lure or a paddle-tail soft plastic is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Shoreline point (6 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Shoreline point (6 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (6 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
Start shallow in spring: gilthead seabream sit in 3 to 35 ft that time of year. Warm water sends them out to 2 to 45 ft; cold water stacks them in 20 to 100 ft. Fish it in early morning and the evening and you'll meet the bite.

The spring pattern is a shallow one: meagre in 12 to 80 ft. As the season builds they drop to 8 to 100 ft, wintering in 33 to 147 ft. Top water on the chart: Deepest basin, a deep basin in the 145 ft range, prime in winter. Time it for the evening.

| Summer | 8 to 100 ft | dusk | open water | see map |

Start shallow in spring: atlantic mackerel sit in 5 to 45 ft that time of year. Warm water sends them out to 15 to 80 ft; cold water stacks them in 30 to 120 ft. Top water on the chart: Sharp break, a drop-off in the 22 ft range, good in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a feather rig or a small vertical jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Shoreline point (6 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Sharp break (22 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Sharp break (22 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Sharp break (87 ft) | Small deep jig |
Early season atlantic bonito use the shallows, holding in 15 to 100 ft. Even in summer they hold at 5 to 90 ft; winter keeps them in 33 to 147 ft. The chart's best answer is Deepest basin — deep basin, 145 ft, prime for winter. Best bite is early morning and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 100 ft | dawn & dusk | Shoreline point (52 ft) | see map |
| Summer | 5 to 90 ft | dawn & dusk | Shoreline point (52 ft) | see map |
| Fall | 8 to 120 ft | dawn & dusk | Sharp break (22 ft) | see map |
| Winter | 33 to 147 ft | midday | Deepest basin (145 ft) | see map |
Come spring, look for garfish tight to the bank in 1 to 15 ft. Expect a summer slide to 2 to 20 ft, then a winter hold in 20 to 60 ft. Start at Shoreline point. It's a point holding about 6 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A slim casting spoon or a surface-skipping fly is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | Shoreline point (6 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | Shoreline point (6 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | Sharp break (22 ft) | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | Sharp break (22 ft) |
Cwb-Ii-3A - North 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.
Cwb-Ii-3A - North carries 15 mapped structure features, topping out (or rather bottoming out) at Deepest basin, about 145 ft down.
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-3A - North 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-3A - North is about 147 ft (45 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-3A - North. 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.
Deepest basin is the top-rated area: a deep basin in about 145 ft of water that rates prime for meagre in winter. Scroll up to the map for the complete spot list by species and season.
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-3A - North is regulated by the Portuguese Directorate-General for Natural Resources, Safety and Maritime Services (recreational fishing).
