Is the Arrábida good for beginner spearfishing?

The water is calm and clear, so it looks ideal, but spearfishing is banned across the whole Prof. Luiz Saldanha Marine Park. The Arrábida is a place to learn freediving and snorkelling, not to start spearfishing. A beginner who wants to hunt must go where it is legal, west of Cabo Espichel, at Foz, Bicas or Meco, open coast far harder than the sheltered coves.

Do I need a licence to spearfish in Setúbal?

Yes. A recreational spearfishing licence is required from age 16, daily, monthly or annually, around 25 euros a year. Spearfishing is allowed in daylight and on a single breath only; scuba is banned.

Is scuba spearfishing allowed in Portugal?

No. Spearfishing is freediving only. Using a speargun on scuba or any surface-supplied air is prohibited nationwide.

Is night spearfishing allowed in Portugal?

No. Spearfishing is permitted in daylight only, from sunrise to sunset. Using artificial light to find or attract fish is banned; a torch is for safety only.

What is the catch limit for spearfishing in Portugal?

The daily limit is 15 kg of fish and cephalopods combined, not counting your single largest specimen. Invertebrates, including spider crab, are capped at 2 kg per day.

How far from the beach can you spearfish in Portugal?

The national rules set no single distance from the shore. What matters is staying out of summer bathing zones and no-take areas like the marine park, and keeping your signalling buoy within 30 m. Check local limits with the Capitania.

The verdict comes from seven water factors and hard safety gates — not ten tabs. Go or stay.

How we score the water

Our own model

Our own forecast engine — not a third-party widget. It weighs these water factors into one go-or-stay verdict for this coast; the 0–10 dial is that verdict, read out as a number.

Swell & wave memory: Height, period and direction of the swell, plus the wake of recent storms — an old storm still stirs the water, and the engine remembers.
Wind & gusts: Speed and gusts, hour by hour — wind speed and an onshore push chop the surface and cut visibility.
Tide phase: Timing and range of the tide, calibrated per coast — big spring tides pull the verdict toward caution.
Water temperature: Sea-surface temperature — sharply cold water vetoes a green verdict.
Currents & outflow: Direction and drift of the current — it pushes you, and it drags turbid coastal water across where you dive.
Rain runoff & air clarity: Rain muddies the water inshore through land runoff, while fog and haze cut visibility at the surface.
Coast shape & exposure: How the coast faces the swell — a sheltered cove keeps the water clean; an exposed, head-on point takes a penalty.

Safety gates

Thunderstorm forecast — an instant red, no exceptions.
An official warning (MeteoAlarm / IPMA) — yellow, or red for the higher ranks.
Missing input data — a would-be green is capped to yellow rather than overstated.
Strong disagreement between forecast models — a green day is pulled back to yellow.
Night hours — where night spearfishing is banned by law the window is forced red; where it is legal (Australia outside NSW, New Zealand, South Africa) it is capped at yellow, never green.

It all folds into a single 0–10 score and one verdict: go or stay.

A forecast, not a guarantee — the sea has the last word.

⛔ Banned here

in the headland's lee today — swell from the quarter/behind

window: Not for hunting. Early morning before the crowds and boats; in summer car access is closed (shuttle only).
tide: For unarmed freediving — any phase; viz best on the flood and with no westerly wind.
shelter: Deeply sheltered cove under the Arrábida ridge, protected from N/NW and westerly swell; one of the calmest spots on the coast.
conditions: Clear water almost year-round, but SPEARFISHING BANNED — total/partial protection zone of the park.
hazard: LEGALLY the core of the marine park, spearfishing heavily penalised. Physically, heavy boat and dive-charter traffic in the cove in summer.
access: Steep descent off the N379-1, entry from the beach/ramp; summer access on foot or shuttle only.

The benchmark Arrábida reef with a dive centre — but it is no-take. Listed to mark the ban, not as a hunting spot.

⛔ Banned here

swell on the quarter today

window: Not for hunting. Best viz on the flood and in calm; very busy in summer.
tide: High tide; at low water the sandbank emerges and currents pull toward the channel.
shelter: Sheltered by the Arrábida ridge from N/NW; faces the Sado mouth to the NNE, shielded from ocean swell but open to easterly wind.
conditions: Almost always calm, but it is a protected zone — freedive yes, SPEARFISHING BANNED.
hazard: The main danger is LEGAL: Luiz Saldanha Marine Park — spearfishing is fined and gear seized. Physically, tidal currents run across the sandbank into the Sado channel.
access: M379 Arrábida road, large car park by the beach, walk-in entry off the sand.

Eastern boundary of the marine park. Gorgeous reef alongside, but hunting is banned — listed as a WARNING, not a destination.

dangerous

exposed head-on to the swell today

window: Early morning in offshore calm, late spring–autumn. Almost always unworkable in winter.
tide: High tide (more water over the bars, less dumping shorebreak); avoid low tide.
shelter: Essentially unsheltered — open Atlantic sand coast; only lays down with a light E/NE offshore.
conditions: Rare window: swell under 0.6 m and offshore wind. Sandy bottom, viz clouds fast in any movement.
hazard: Powerful shorebreak and rip currents on open sand — the real killer here; plus boat traffic near the Tróia channel. Sandy bottom means little fish inshore.
access: Ferry/catamaran from Setúbal to Tróia, then on foot over the dunes to the ocean side; by car via the N253-1.

The only legal side by this town — but it is a sand barrier, not a reef. Scout from land only; fish hold near rare rock/oyster patches. ⚠️ Real beach but hazard is DISHONEST/inverted: Troia-Mar is a calm, sheltered, Blue Flag, family/kitesurf beach with low wave action (sources: 'shallow calm waters where everyone brings the kids') - NOT 'powerful shorebreak and rip currents, the real killer.' That hazard appears fabricated. Coords also wrong: real beach is at ~38.486,-8.908 (Google pin) / 38.491,-8.908 (praias.pt); claimed -8.898 is ~0.9 km too far WEST toward the estuary/marina tip. The 'lado atlantico' label is also dubious - several sources describe it facing the Arrabida across sheltered water.

SOLO is the biggest risk: underwater you can black out from lack of oxygen silently and fatally, with no one around. Solo is never truly «safe». Below are the best weather windows; carry a buoy, tell someone your plan and exit time, and any doubt — don't go.

Law

🦀 spider crab open (season 16.06–14.02)

✓Spearfishing licence required, daily/monthly/annual (~€25/yr). Speargun = licence required. (DL 246/2000, art. 12.º + 12.º-A; fees in , .) There is no minimum age for the licence, but under-16s are exempt from holding one when fishing accompanied by a licence holder (art. 12.º n.º 2 al. b).
✓Hand-gathering shellfish with NO gear — no licence; but if a speargun is on the dive, a spearfishing licence is required (DL 246/2000, art. 12.º n.º 1; ).
✓Night prohibited: spearfishing only in daylight (sunset→sunrise not allowed). Artificial light as a means of finding/attracting fish is banned — a torch for safety only (, art. 8.º/3 + 3.º/5; DL 246/2000, art. 14.º n.º 1 d).
✓Signalling buoy MANDATORY for spearfishing: buoy/float with an «Alfa» flag (red/orange/yellow, ≥8 L), no more than 30 m from the diver (, art. 4.º/2).
✓Spearfishing daily limit: fish + cephalopods — 15 kg (excluding the largest specimen). General rod-and-line recreational fishing — 10 kg (, art. 12.º/1).
✓Invertebrates (including spider crab) — 2 kg/day total (, art. 12.º/2).
✓Spider crab: min. carapace 12 cm; (closed season) 15.02–15.06 — applies to recreational gathering too (, ; table).
✓Min. sizes: robalo 36 cm, sargo 17 cm, dourada 19 cm, choupa 23 cm, corvina 42 cm; octopus 750 g ( + EU Reg. 2019/1241; minimum-size table).
✓Grouper — fully protected, may not be taken (, art. 10.º + ).
✓Breath-hold only: spearfishing may be practised in apnea alone. Scuba, rebreather and hookah are banned; the speargun may not be powered by a detonating charge or by compressed gas (DL 246/2000, art. 9.º n.º 3 — o antigo art. 6.º foi revogado).
✓The catch may NOT be sold: displaying for sale, offering or selling recreational catch is prohibited — it is for the fisher, the household, or donation to charitable, scientific or museum institutions (DL 246/2000, art. 7.º).
✓A loaded speargun out of the water is an offence (DL 246/2000, art. 14.º n.º 2 f). Same article: no fishing closer than the legally set distance from concessioned beaches during the bathing season (n.º 2 d), nor in places closed for health or marine-traffic reasons (n.º 2 e). The exact metres come from the regulation and the capitania — check before you go.
✓Distances between people: at least 20 m from another spearfisher (, art. 6.º n.º 3) unless you agree otherwise; from a boat, 50 m from other vessels, divers and set gear (art. 6.º n.º 2); every vessel must keep 50 m from your signalling buoy and from boats flying flag Alfa (art. 7.º n.º 6). The figure that circulates — «30 m between hunters» — is wrong: 30 m is the distance to YOUR OWN buoy.
✓What you may take into the water: the CAPTURE gear on a spearfishing dive is the speargun, a shellfish knife, a gaff (puxeiro) and an arrelhada (, art. 3.º n.º 3). That is not a ban on everything else: art. 4.º n.º 1 expressly allows equipment for cold protection, for buoyancy, for protection or safety and for carrying the catch, and any other equipment that does not permit the direct capture of specimens. Bait and groundbait are PROHIBITED in spearfishing (art. 5.º n.º 3). You may not carry or keep a speargun and a breathing apparatus aboard at the same time, nor carry the gun ready to fire out of the water or in a zone where spearfishing is banned (art. 3.º n.º 6). On any recreational-fishing boat the whole crew wears a lifejacket (art. 4.º n.º 3).
✓Where recreational fishing is closed altogether (, art. 8.º n.º 1): in marked shipyard zones (no exception) and in aquaculture establishments — in the LATTER only, fishing is possible when the concession-holder or owner formally authorises it; the shipyard bar has no such carve-out; within 100 m of the mouth of any marked sewage outfall; over beach-concession waters, to the extent the POOC sets; and in other zones closed by the port or maritime authority. For spearfishing and boat fishing specifically (n.º 2) the navigation channels of port and river bars, the approach channels and the buoyed channels are closed. There is NO «300 m from the beach» rule on the mainland — that number comes from Madeira's own act; on the mainland the distance is set by the POOC and by the capitania's edital.
✓The border rivers Minho and Guadiana: spearfishing is BANNED along both international stretches — bilateral Portugal-Spain agreements, art. 9.º n.º 3 (Minho, RAR 34/2023, in force since 26-05-2023) and art. 6.º n.º 1 (Guadiana, RAR 173/2025, in force since 07-12-2025), both reading «É proibida a pesca submarina». On the Guadiana it is also a serious offence (art. 19.º), and a 100 m strip alongside the Sapal de Castro Marim reserve is closed separately (art. 5.º). The stretches run from the confluence with the Trancoso / the Chança down to the closing line at each mouth.
✓On the other Portuguese-Spanish border river stretches (outside the TIRM and the Guadiana maritime-jurisdiction zone) — Decreto 30/88, art. 6.º n.º 1: harpoons, gigs, tridents and any blunt instrument used to take fish are prohibited (al. e), as is «a pesca ou caça subaquática» with artificial light, and night fishing (al. g).

⛔ Grouper (Epinephelus) — fully protected, capture PROHIBITED.
⛔ Seahorses (Hippocampus) — protected.

Rules change. Before heading out, check with DGRM / ICNF / Capitania and the defeso table.

Safety protocol

Sets: watch the wave trains ≥15 min before entering; Hmax ≈ 2×Hs, the wash can run 50 m past the foam line. A lull >10 min with period >12 s = a big set «overdue», do NOT enter; enter right after a full set passes and re-check at minute 30.
Exit FIRST: find your exit AND a backup before entering. At Cabo Raso/Arriba a 0.5 m rise in swell makes a boulder exit impossible — getting pinned/unable to climb out is the main killer here.
Headland rip: at Cabo Raso there is a permanent topographic rip regardless of the model — locate it, enter/exit on the windward side, never swim against it.
Cold: wetsuit per the SST chip; the first shiver = a metabolic surge and a drop in breath-hold → get out at the first steady shiver. Cap the session at 45–60 min below 15 °C.
Solo discipline: buoy up; tell someone the spot and exit time; conservative breath-hold (never push it in cold/murky/surfy water); visibility <3 m — don't enter.
Nortada (Jun–Sep): wind builds from midday — be out of the water by ~11:00; the chop builds — get out.
UV 11:00–15:00 (UVI ≥6): sunscreen and cover up on the surface interval.
Solo is a fundamental risk (hypoxic blackout with no buddy). Any doubt = No-go.

Spearfishing in Setúbal / Tróia: spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

Spearfishing around Setúbal and Tróia works off the Sado estuary mouth, under the Arrábida ridge. The water is calm and clear, which earns it a beginner reputation, but the prettiest coves sit inside the Prof. Luiz Saldanha Marine Park, where spearfishing is banned. Legal hunting starts only west of Cabo Espichel, at Foz, Bicas and Meco. The Sado outflow lowers visibility, which opens on the ebb. A licence is required, freediving only.

TL;DR

Spearfishing is banned throughout the ENTIRE Prof. Luiz Saldanha Marine Park along the Arrábida, not just the full-protection cores. It is legal only west of Cabo Espichel: Foz, Bicas and Meco.

The calm Arrábida coves, Figueirinha and Portinho, are excellent for freediving and snorkelling, but spearfishing there is fined and gear is seized.

The Atlantic sand of Tróia is a barrier beach, little fish inshore and visibility that clouds fast; it is a scout from land, not a hunting spot. The Sado outflow lowers visibility, which opens on the ebb.

National rules: licence required from age 16, freediving only, a signalling buoy within 30 m of the diver, minimum sizes and a 15 kg daily limit.

Can you spearfish in the Arrábida marine park?

No. Spearfishing is banned throughout the entire Prof. Luiz Saldanha Marine Park, not only in the full-protection cores. Wardens fine you and seize the gear. Beaches like Figueirinha, on the eastern boundary, and Portinho da Arrábida, the benchmark reef with a dive centre, are no-take: you may freedive and snorkel, but not hunt. The water stays clear almost year-round, which draws crowds and is why the Arrábida keeps surfacing in beginner searches. To hunt within the law you must leave the park: only west of Cabo Espichel, at Foz, Bicas and Meco.

Where can you spearfish in Setúbal and Tróia?

By the town, everything that holds fish is reef inside the marine park, where spearfishing is banned, so there is no legal hunting spot next to Setúbal. The ocean-facing Atlantic sand of the Tróia peninsula is a sand barrier, not a reef: it holds little fish inshore, the sandy bottom clouds fast, and it is a scout from land at best. The Sado mouth and spit are sheltered from ocean swell, but the estuary outflow cuts visibility; the best water comes on the ebb. For real reef within the law, head west of Cabo Espichel, to Foz, Bicas and Meco on the Sesimbra side, open oceanic coast unlike the calm park coves.
