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.

Law
- ✓Spearfishing licence mandatory; the AUTONOMOUS COMMUNITY issues it (not the State) and it is valid in the exterior waters of the whole coast. Free-diving only — scuba is banned (, art. 3).
- ✓Spearfishing catch may not be sold or traded — it is non-commercial fishing ().
- ✓Night prohibited: spearfishing only in daylight (sunset to sunrise not allowed) — , art. 16.d.
- ✓Marker buoy MANDATORY: mark your position with a clearly visible buoy and stay within 25 m of it — , art. 15.
- ✓Never keep the speargun loaded out of the water — , art. 16.a.
- ✓Keep at least 300 m from professional fishing vessels that are working — , art. 12.b.
- ✓Spearfishing banned in marine reserves/protected zones (without a special permit), in ports and at busy beaches/bathing areas. The exact distance to bathing zones is set by the autonomous community.
- ✓Min. sizes by ( + + EU 2019/1241): sea bass 42 cm (rec.) / 36 cm / 25 cm Mediterranean / 22 cm Canaries; gilthead bream 20 cm and white seabream 23 cm in the Mediterranean (EU 2019/1241); grouper 45 cm. See your zone's species card.
- ✓Only species in Annex I of may be taken; keeping, landing or transporting undersized specimens is prohibited.
- ✓The licence needs a medical fitness certificate for free-diving and civil-liability insurance (or a federative licence, which includes it). Mandatory in the Basque Country/Murcia/Asturias/Galicia; the federative licence covers it in Galicia/Balearics/Cantabria; the Canaries and Andalusia do NOT require it for the individual licence (a responsible health declaration). Minimum age generally 16 (14 in Andalusia).
- ✓There is no fixed national catch cap (, art. 5 delegates it to the communities); the standard is 5 kg/person/day, with 1 specimen allowed not to count (Canaries art. 38.3; Murcia; Galicia; Basque Country). Protected species have per-piece quotas.
- ✓Galicia: «Clase C» licence (submarina), procedure PE405A on the Xunta portal; minimum age 16, medical certificate required. Galicia recognises spearfishing licences from other communities and the EU. sede.xunta.gal (PE405A).
- ✓No-take zone: Atlantic Islands National Park (Cíes, Ons, Sálvora, Cortegada) — spearfishing banned (see zones on the map).
- ⛔ Seahorses (Hippocampus) — protected (RPE).
Rules change and are REGIONAL. Before heading out, check with the competent autonomous community (licence) and the min-size table in force.
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. On a rocky/boulder shore a 0.5 m rise in swell can make the exit impossible — getting pinned/unable to climb out is the main killer.
- Headland rip: prominent points often have 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.
- Afternoon wind: on many coasts the wind builds from midday — plan to be out of the water by midday; 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 O Grove: spots, seasons and rules
Spearfishing in O Grove depends on the side of the peninsula. The west tip at San Vicente do Mar/O Con Negro has rocky ground, drop-offs and swell exposure; A Lanzada is a shore-break sea bass option only with little sea. Inner Arousa is the sheltered listed ground, with sand and low rock. Legally this is Galicia: use the Clase C PE405A route and treat the Atlantic Islands National Park no-take zones as hard limits.
TL;DR
- O Grove is a Rías Baixas peninsula: west-facing San Vicente and A Lanzada are exposed, while inner Arousa is more sheltered.
- The Atlantic Islands National Park is the named no-take rule; Complexo Ons - O Grove is advisory Natura 2000, not an automatic ban.
- Galicia means Clase C through PE405A, minimum age 16 and medical certificate.
Where can you spearfish in O Grove?
West is exposed. San Vicente do Mar/O Con Negro has drop-offs, grouper and bream, but takes swell. Punta Faro is lighthouse rock with stone entry and moderate exposure. A Lanzada works only with little sea. Inner Arousa is sheltered. Illa de Arousa has rocky points and shallow reef, with a protected-zone warning.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| San Vicente do Mar (O Con Negro) | Rocky west-tip ground | Western drop-offs | - | - | The source names grouper and bream, and marks it exposed to swell. It is also flagged under Complexo Ons - O Grove as Natura 2000 advisory. |
| Punta Faro de O Grove | Rocky lighthouse point | Rock bottom | - | Over stones | Stone entry and moderate exposure in the source. |
| A Lanzada (lado O Grove) | Exposed beach end | Shore break | - | - | Sea bass in the shore break, only with little sea. |
| Costa interior da ria de Arousa | Sheltered inner coast | Sand and low rock | - | - | NE side of the peninsula, well sheltered in the source. |
| Illa de Arousa | Island with rocky points and shallow reef | Shallow reef and rock | - | - | Mind protected zones. The source does not make the whole island no-take. |
Which zones are closed to spearfishing in the Ría de Arousa?
The Galicia block names the Atlantic Islands National Park, Cíes, Ons, Sálvora and Cortegada, as closed to spearfishing. San Vicente do Mar/O Con Negro in Natura 2000 Complexo Ons - O Grove and Illa de Arousa carry advisory protected-zone notes. Check local rules; those notes are not whole-area bans.
What fish can you spearfish in O Grove?
The O Grove spot text names grouper and bream at San Vicente, and sea bass at A Lanzada. The Cantabrian-NW list also includes European seabass, gilthead seabream, salema, bogue, black seabream, grey mullet, red porgy, striped red mullet, octopus, conger and pollack. Legal sizes include seabass at 42 cm, gilthead bream at 19 cm and octopus at 1 kg.
When is the best time to spearfish in the Rías Baixas?
The source gives no month window for O Grove. It gives Atlantic tide regime, upwelling coast and a bad W to NW sector. Use that as a conditions filter: San Vicente and A Lanzada need little sea, Punta Faro is moderately exposed, and inner Arousa is sheltered. The webcam helps read the surface, not underwater visibility.
Do I need a license to spearfish in Galicia?
Yes. The Galicia item says Clase C spearfishing licence, PE405A on the Xunta portal, minimum age 16 and a required medical certificate. Galicia also recognises spearfishing licences from other Spanish autonomous communities and the EU. National rules still apply: freediving only, no scuba, daylight only, visible buoy within 25 m, no loaded speargun out of water, and no catch sale.
