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 — forced red; the window is closed after dark.

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.

What it is

A marine instrument,
go / no-go for solo hunting.

spearo.app folds wind, wave, swell period, visibility, tides, water temperature and risk into a single verdict — go to the spot or not. It computes 7 days ahead from open marine models (Open-Meteo, IPMA), with no sign-up and no accounts. Built for solo spearfishing off the rocks, where any mistake costs dearly.

Now live: 1152 spots across 189 stretches of coast — mainland Portugal, Madeira and the Azores.

The call is on the rock.

The models set the window. Whether you go in is read only at the water: count the sets, watch the surge on the entry. If in doubt, you don't get in.

Entry points

Where to get in
off the rocks.

Scouted entries, coloured by today. The colour is the sea state at the spot, not a guarantee: the wash and a slippery entry you judge on site.

Open the seafloor map
Boa Nova headland / Leça lighthouseBoa Nova rocky promontory · Capela da Boa Nova / Farol de Leça headland
borderline
best candidate for today
exposed head-on to the swell today
window
Early morning (calm before the sea breeze), summer to early autumn when swell drops and water warms slightly. Water is cold regardless — 5–7 mm suit.
tide
Low-to-mid tide on the push: more exposed rock to enter on and the reef sits closer. At high water the rocks cover and entry gets harder.
shelter
Almost no shelter: an open Atlantic headland. The north side of the rocks gives slight cover from a southerly, but nothing against the prevailing NW swell.
hazard
Shorebreak slamming the rock platforms on exit is the dominant danger — it traps you if swell builds even slightly. Cold water and currents along the headland. Slippery-rock entry and exit.
access
Park by the Boa Nova lighthouse / Casa de Chá; walk down to the rock platforms on either side of the sandy pocket. Enter from the lee side of the rocks.

The best rocky-reef entry on this coast: the offshore 'Pelo Negro' reef (8–21 m, canyon walls) runs out from this headland. Scout from land first — the rock exit is everything.

Google Maps
Castelo do Queijo / Fort of São Francisco XavierGranite promontory (Porto border) · Castelo do Queijo / Forte de São Francisco Xavier
dangerous
swell on the quarter today
window
Early morning in a rare calm summer window. Otherwise, land scouting only.
tide
Low tide exposes more granite platforms to enter from, but also the shallow teeth under the break. Enter only on a calm low water.
shelter
Exposed granite promontory at the Porto–Matosinhos line — almost no shelter, waves hit from several sides. The nook north of the fort is slightly calmer.
hazard
Rough cold sea over granite teeth: shorebreak on the rocks at exit and risk of being thrown onto / wedged in stone as swell builds. Awkward slippery rock entry; boat traffic near the Leixões harbour mouth.
access
Park by the fort on Av. Montevideu; drop to the small rocky beach/platforms at the base of the promontory. Enter on the north, lee side.

Technically on the Porto border (Nevogilde/Foz), but it is the nearest southern rocky promontory of this stretch: documented as a fishing rock with awkward rock entry. Scout from land first.

Google Maps
Praia da Meia Laranja (rocks by the tidal pools)Rocks by the Leça tidal pools · Praia da Meia Laranja (rocks by Piscina das Marés)
closed
exposed head-on to the swell today
window
Early morning outside bathing season (the pools open Jun–Sep with lifeguards and crowds). In summer go before 9 am.
tide
Low tide: rock ledges and pools are exposed, safer entry. At high water there are bathers and shorebreak on the rocks.
shelter
Open west-facing shore with almost no swell shelter. The rock ledges damp the wave right at the edge, but this is a bathing beach, not a refuge.
hazard
Chief issue: a guarded bathing zone beside a National Monument (the tidal pools) — hunting among bathers is banned and inappropriate. Plus shorebreak on the rocks and murky water.
access
From the Leça seafront promenade, drop to the rocky Meia Laranja section just south of the pools. Park along Av. da Liberdade.

More a fallback/scout than a hunting spot: monument and bathing zone adjacent. Fine for snorkel/training as a bad-day backup, not for shooting in a crowd.

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.

One morning glance — and you know.

What's in season,
what the law says.

In season now: Sea bass, White seabream, Gilthead bream, Salema, Meagre, Mullet · coming soon: Octopus (Sep)

In season now
  • Robalo (sea bass)
    <4 m · end of ebb → start of flood · dawn/dusk
    Prime target. Shy of light — pick early/twilight windows.
  • Sargo (white seabream)
    1–5 m · flood (rides the surf onto the reef) · dawn
    Dominant reef target. Visibility matters more than time of day.
  • Dourada (gilthead bream)
    1–4 m · flood over sand/weed · dawn
    Very skittish — static ambush.
  • Salema
    0–2 m · — · daytime
    Easiest target at 0–6 m. ⚠️ Do NOT eat the head/guts (ichthyosarcotoxism).
  • Tainha (mullet)
    0–2 m · — · —
    Extremely wary; murky water HINDERS it. Opportunistic, in calm coves.
  • Corvina (meagre)
    1–6 m (marginal) · — · twilight
    Near the Tagus mouth, NOT on the Guincho rocks. Adults mostly at 5–75 m. ⚠️ CLOSED 1–30 June (defeso).
  • Santola (spider crab)
    1–10 m · low water (reef shelf exposed) · calm morning (≤force 2)
    Carapace ≥12 cm. Peaks Jul–Aug. CLOSED 15.02–15.06. Limit 2 kg/day.
Law
🦀 spider crab open (season 16.06–14.02)
  • ✓Spearfishing licence required (16+), daily/monthly/annual (~€25/yr). Speargun = licence required.
  • ✓Hand-gathering shellfish with NO gear — no licence; but if a speargun is on the dive, a spearfishing licence is required.
  • ✓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.
  • ✓Signalling buoy MANDATORY for spearfishing: buoy/float with an «Alfa» flag (red/orange/yellow, ≥8 L), no more than 30 m from the diver.
  • ✓Spearfishing daily limit: fish + cephalopods — 15 kg (excluding the largest specimen). General rod-and-line recreational fishing — 10 kg.
  • ✓Invertebrates (including spider crab) — 2 kg/day total.
  • ✓Spider crab: min. carapace 12 cm; (closed season) 15.02–15.06 — applies to recreational gathering too.
  • ✓Min. sizes: robalo 36 cm, sargo 17 cm, dourada 19 cm, choupa 23 cm, corvina 42 cm; octopus 750 g.
  • ✓Grouper — fully protected, may not be taken.
  • ⛔ 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 Matosinhos / Leça da Palmeira: spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

Spearfishing around Matosinhos and Leça is cold, urban and narrow-window. The Boa Nova headland has the best reef structure, while Meia Laranja is a shallow fallback by the tidal pools. West exposure, Leixões harbour traffic and possible Douro turbidity make visibility and exits unreliable. Wait for a very small swell, light easterly wind and an early morning, then scout the rock exit from land before entering.

TL;DR

  • Matosinhos and Leça are urban, exposed and port-influenced, not clean wilderness shore diving.
  • Boa Nova / Leça lighthouse is the best reef entry; Meia Laranja is a cautious fallback.
  • Castelo do Queijo is red/scout and stays out of the recommended table.

Best spearfishing spots in Matosinhos / Leça

Only non-red, non-scout entries are listed. Both require small swell and strong swimmer awareness.

SpotTypeDepthLevelAccessNotes
Boa Nova Chapel / Leça LighthouseExposed rocky headlandShallow entry, reef gaining depthIntermediate to advancedPark by the lighthouse or Casa de Chá and walk down to the rock platformsBest reef structure on this stretch, linked to Pelo Negro reef. The rock exit is the critical safety check.
Praia da Meia LaranjaRocks by the Leça tidal poolsShallow ledges and poolsCareful intermediateLeça seafront, down to the rocky section south of the poolsMore fallback than main hunting spot. Avoid bathing hours, shorebreak and swimmers.

When are Leça conditions worth it?

The coast faces west and takes NW swell directly. Boa Nova wants swell under about 0.8 m, light easterly wind and early morning before the sea breeze. Meia Laranja is shallower and wants 0.6 to 0.8 m or less. Low to mid tide helps read the platforms but exposes sharp rock. Leixões harbour traffic and the Douro plume, about 6.6 km away, can reduce the margin for error.

FAQ

What is the best Leça spearfishing entry?

Boa Nova / Leça lighthouse, but only on a rare small-swell window with a planned rock exit.

Can I hunt by Piscina das Marés?

Only with caution outside swimmer conflict. Meia Laranja is a fallback, not a prime hunting spot.

Why exclude Castelo do Queijo?

It is marked red/scout, with exposed granite, shorebreak and nearby harbour traffic.

Does the Douro affect visibility?

It can. The mapped Douro plume is about 6.6 km away, and rain or swell can dirty the water.

What Portugal rules apply?

License from 16, breath-hold only, daylight only, flagged buoy within 30 m, minimum sizes and daily catch limits.
