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.

The water column

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: 1152 spots across 189 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.

In season now
  • sea bream (sargo)
    Diplodus argenteus · 0–12 m · legal
  • black drum
    Pogonias courbina · 1–20 m · ⚠️ closed season/limit
    Black corvina: mind the reproductive closure (winter). Big fish = better breeders, release them.
  • flounder
    Paralichthys spp. · 1–20 m · legal
  • brotula
    Urophycis brasiliensis · 3–25 m · legal
Law
  • 🚫 Isla de Lobos (NP, Dto 233/024) and Cerro Verde e Islas de la Coronilla (SNAP) — no-take: no hunting. Cabo Polonio — advisory ring, avoid hunting.
  • Sea lions, turtles and cetaceans — protected; do not disturb.
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 Punta del Diablo: spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

Punta del Diablo is more exposed and less sheltered than La Paloma, but it has true salty Rocha water. The town rocky point is the first check; Cerro Rivero and the outer La Viuda restinga add shallow channels when the sea settles. South to southeast swell can shut everything down. North wind after a calm spell is the clean-water sign. Avoid Cerro Verde and Islas de la Coronilla as sensitive protected-area ground tied to green turtles.

TL;DR

  • Punta del Diablo is Rocha's wilder rocky shore option.
  • Check the town point, Cerro Rivero and the La Viuda outer restinga.
  • Treat Cerro Verde and Islas de la Coronilla as no-take sensitive areas.

Punta del Diablo shore spots

There is no harbour exit to save a bad call. Walk the rocks first and skip any washed-out restinga.

When does Punta del Diablo work?

North wind and falling S/SE swell are the main clues. DINARA sport-fishing rules apply, with special care around black corvina closures and protected fauna. Sargo, corvina, flounder and grouper are realistic, but Cerro Verde should be treated as no-take because of SNAP and turtle sensitivity.

FAQ

Is it clearer than Montevideo?

Usually yes, but only when S/SE swell has settled.

Can you spear Cerro Verde?

Do not use it as a hunting spot; treat it as no-take.

What fish are realistic?

Sargo, corvina, flounder and some grouper.

What wind helps?

North wind after calm days.

Do DINARA rules apply?

Yes, including permit checks and black corvina closure awareness.
