996-acre Internacional-Guadiana 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 Algarve 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 25 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.
On the chart, Internacional-Guadiana draws 996 acres inside 5.4 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 92% of this chart. End to end it runs roughly 1.7 mi, about 1.6 mi across. Closest neighbour on DepthScout: Cwb-I-7, 3 mi west 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.

In spring, atlantic bonito run shallow here, mostly 4 to 25 ft. Summer keeps them at 1 to 25 ft, and they winter in 6 to 25 ft. Deepest basin is the standout, a deep basin at roughly 23 ft, rated prime for winter atlantic bonito. Time it for early morning and the evening.

| Spring | 4 to 25 ft | dawn & dusk | Sharp break (5 ft) | see map |

Come spring, look for greater amberjack tight to the bank in 4 to 25 ft. Through summer count on 2 to 25 ft; the winter hold is 6 to 25 ft. Start at Sharp break. It's a drop-off holding about 5 ft of water and rates prime come spring. Prime time lands in early morning and the evening.

Spring puts common dentex in skinny water — 4 to 25 ft is the zone. Summer fish stay in 4 to 25 ft, and winter fish hold in 6 to 25 ft. Summer common dentex concentrate at Sharp break, a prime-rated drop-off around 5 ft. Warm-month bites cluster around early morning and the evening.

Spring puts bluefish in skinny water — 3 to 20 ft is the zone. Warm water sends them out to 4 to 25 ft; cold water stacks them in 8 to 25 ft. Sharp break is the standout, a drop-off at roughly 5 ft, rated good for summer bluefish. Plan around early morning and the evening in the warm months. A popper (early/late) or a metal jigs in the rips covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Sharp break (5 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 4 to 25 ft | dawn & dusk | Sharp break (5 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Sharp break (5 ft) | Pencil popper, Big metal |
| Winter | 8 to 25 ft | midday | Deepest basin (23 ft) | Metal jig worked slow (southern waters) |
When the water first warms, red mullet slide up into 2 to 25 ft. There's no big seasonal slide here — summer means 1 to 25 ft, winter 5 to 25 ft. Start at Deepest basin. It's a deep basin holding about 23 ft of water and rates prime come winter. The feeding windows run early morning and the evening.

Early season gilthead seabream use the shallows, holding in 2 to 25 ft. Even in summer they hold at 1 to 25 ft; winter keeps them in 5 to 25 ft. The chart's best answer is Deepest basin — deep basin, 23 ft, prime for winter. Best bite is early morning and the evening.

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 Internacional-Guadiana 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.

Internacional-Guadiana is about 25 ft (8 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 atlantic bonito, greater amberjack, common dentex, bluefish, red mullet, gilthead seabream, garfish, atlantic mackerel roster for Internacional-Guadiana. 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 23 ft of water that rates prime for atlantic bonito in winter. The map above holds the full rated-spot list for every species and season.
For atlantic bonito, 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 Internacional-Guadiana is regulated by the Portuguese Directorate-General for Natural Resources, Safety and Maritime Services (recreational fishing).
