Piriápolis spearfishing forecast — Uruguay

Q: Where can you spearfish in Piriápolis?

Punta Fría, Playa Grande, Punta Colorada and Punta Negra are the main shore names. Bajo Escondido is offshore and better by boat.

Q: What is the underwater visibility in Piriápolis today?

There is no fixed number. North wind improves the odds; SE to S sea usually makes the water dirty.

Q: What fish can you spear in Piriápolis?

Sargo, mullet, yellow corvina, flounder and brótola appear in the local and national records. Black corvina has a DINARA closure warning.

Q: When is the best season to spearfish in Piriápolis?

Punta Fría is marked spring to autumn. Piedra Mora is noted for July to September, but wind and water color still decide the day.

Q: Is spearfishing legal in Uruguay?

Yes, under DINARA rules, with a sport-fishing permit where required and respect for zones, species, closures and sizes.

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.

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.
