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.

On the rock

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

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.

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.

One morning glance — and you know.

Reference

What's in season,
what the law says.

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
  • ✓DINARA sport-fishing permit; sport fishing is open except for zones/species/gear that need a permit. Res. 388/2015 froze new 'from-shore' permits. Sale prohibited.
  • ✓Precautionary closed season for black corvina (DINARA) and winter brótola; respect minimum sizes.
  • ⛔ 🚫 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.

Rules change. Before heading out, get the DINARA sport-fishing permit and respect the black-corvina closure and minimum sizes.

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.

FAQ — spearfishing in Chuy

Where can I spearfish in Chuy?

Chuy has rock entry points such as Barra del Chuy (restinga/playa). Chuy is the border hub with Brazil; its coast is Barra del Chuy: a long, exposed beach, clear salt water but little rock — more surf-casting than spearing. Below you'll find each spot (access, shelter and hazards) and today's forecast.

When is the best season in Chuy?

Summer (Dec–Mar) — warm clear water; sudestada muddies it for days. Best windows on N/NW offshore wind.

How cold is the water in Chuy?

Summer 18–22 °C — 3–5 mm suit; winter 10–14 °C — 5–7 mm. Atlantic, clearer to the east.

Is Chuy good for a beginner?

Moderate: Atlantic restingas; sudestada muddies it for days — catch the N/NW windows.

Do I need a licence in Chuy?

In Chuy (Uruguay) there's no specific spearfishing regulation (Ley 13.833 + Dto 149/997, DINARA); it's done on breath-hold, with a buoy. Note: Isla de Lobos and Cerro Verde/Islas de la Coronilla are no-take (SNAP) — no hunting; Cabo Polonio carries an advisory ring. Mind the black-corvina closure. See the guide.
