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.

Visibility and what drives it — post-storm clearing, river plume, temperature and the thermocline.
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: 3016 spots across 406 stretches of coast — mainland Portugal, Madeira and the Azores.

On the rock
The forecast is the plan.
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
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.

Check the cam BEFORE you leave. Foam, brown/green murk, or waves washing the entry rocks = No-go. At night/in fog the cam is useless — treat it as «unknown», NOT «green».

Reference
What's in season,
what the law says.
In season now
- amberjack (sea salmon)Chubut: free permit + Valdés cupo (2 fish >5 kg / 4 fish <5 kg). Respect it.
- grouper
- yellowtail
- sea bass (chernia)
- flathead
- croaker⚠️ Buenos Aires: spearfishing is NOT regulated (grey zone). No published size or quota — we do not promote «go and shoot» on natives until the province text is verified. Check first.
Law
- ✓The licence is PROVINCIAL. In the Patagonian sea (Río Negro — Las Grutas; Chubut — Puerto Madryn) spearfishing is allowed: Chubut issues a FREE spearfishing licence. In Buenos Aires (Mar del Plata) you get the sport-fishing licence via Ciudadano Digital and spearfishing is regulated by Flora y Fauna.
- ✓The Patagonian Continental Sport-Fishing rules ban spearfishing ONLY in inland waters (rivers/lakes) — NOT the sea. Respect provincial sizes/quotas (grouper, salmón de mar, amberjack) and closed zones.
- ⛔ 🚫 All National Parks (Islote Lobos, Monte León, PN Tierra del Fuego; APN Res 199/2024) — spearfishing banned. Península Valdés / Puerto Pirámides — whale sanctuary: no-take.
- ⛔ ⚠️ Buenos Aires: spearfishing not regulated (grey zone) — do not hunt natives until the province text is verified. Río Negro Ley 5.706/2024: apnea only, no night.
- ⛔ Sea lions, penguins, cetaceans and seabirds — protected; do not disturb.
Rules are PROVINCIAL and vary. Before heading out, check with your province's authority (Chubut — free licence; Río Negro; Buenos Aires — Ciudadano Digital / Flora y Fauna); sea spearfishing is allowed, banned only in inland waters.
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.
