Compiled by the spearo sea-state engine · How it works →

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.

01
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.
02
Wind & gusts
Speed and gusts, hour by hour — wind speed and an onshore push chop the surface and cut visibility.
03
Tide phase
Timing and range of the tide, calibrated per coast — big spring tides pull the verdict toward caution.
04
Water temperature
Sea-surface temperature — sharply cold water vetoes a green verdict.
05
Currents & outflow
Direction and drift of the current — it pushes you, and it drags turbid coastal water across where you dive.
06
Rain runoff & air clarity
Rain muddies the water inshore through land runoff, while fog and haze cut visibility at the surface.
07
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.

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.

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.

    ⚠️ 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.
