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.

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.

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.

    ⚠️ 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.

Spearfishing in Mar del Tuyú: spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

Spearfishing in Mar del Tuyú should be framed honestly. This Partido de la Costa shore is sandy, often turbid and short on rock, so it is not a strong shore-hunting destination. The San Bernardo pier can hold some life around pilings, including corvina, but it also brings anglers, lines and low visibility. The tide is micro; sudestada wind, surf and Plata-influenced turbidity decide the day. Legally, this is Buenos Aires province and the modality needs confirmation before any harvest.

TL;DR

  • Mar del Tuyú is a weak spearfishing case: sand, turbidity and little real reef structure.
  • San Bernardo pier is the only practical reference, and even that is marginal.
  • Buenos Aires province is the authority; verify the unclear spearfishing status before harvesting.

Best spearfishing spot near Mar del Tuyú

This is a marginal recognition point, not a robust best-spot list.

Muelle de San Bernardo (Mar del Tuyú)Pilings over sandShallow, surf dependentScout onlyFrom shore, away from bathers and anglersPilings may hold corvina and small fish, but turbidity, fishing lines and lack of reef make it weak.

Mar del Tuyú conditions and legality

The main limitation is habitat: sand and dirty water leave little for a spearfisher to work with. A pier can concentrate fish, but it also creates conflict with other users. If the water is brown from sudestada or shorebreak, do not expect clarity below. Buenos Aires is the correct province, and spearfishing is treated as an unclear modality, so check provincial guidance before taking native fish. Observation dives are the safer default when the rule or visibility is doubtful.

FAQ

Is Mar del Tuyú good for spearfishing?

Not really. It is mostly sand and turbid water.

What is the local mark?

San Bernardo pier, but only as a marginal scout point.

What ruins conditions?

Sudestada, shorebreak and brown water.

Which province regulates it?

Buenos Aires. Check provincial guidance before harvesting.

Does tide matter?

Less than wind and turbidity; the local tide is micro.
