The verdict comes from seven water factors and hard safety gates — not ten tabs. Go or stay.
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.
Safety gates
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.
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.

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.
Spearfishing in Puerto Madryn is a Chubut and Golfo Nuevo story. The city has real history, with FAAS founded here in 1962, but the modern plan is still simple: provincial spearfishing licence, respect quotas, and dive restingas when the macro tide relaxes. The gulf can give 8-20 m visibility from October to April, with water from 7 to 22 °C, and west wind is offshore, so it often cleans and flattens the surface. Punta Este, Las Piedras, Punta Cuevas and Punta Indio are the hunting names. The wrecks are diving and heritage, not a shortcut to fish.
Madryn has many dive names, but spearfishing is easier to understand by restinga. Golfo Nuevo platforms and shallow reefs hold sea salmon, grouper and chernia. Wrecks stay in the dive circuit.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Punta Este | Restinga | 5-12 m | Intermediate | Coast/restinga depending on tide | Prime hunting point for sea salmon and grouper. Time it around slack. |
| Las Piedras / Parque Las Piedras | Rocky reef | Around 11 m | Intermediate | About 500 m, dive and shore access | Central local name. It shows why Madryn hunting is about restingas rather than flat beaches. |
| Restinga de Punta Cuevas | Rock platform | 6-10 m | Entry-level with correct tide | Inside the city | Shore entry with sea salmon and grouper. Better for learning the local pattern than chasing depth. |
| Punta Indio | Shallow reef | To 8 m | Intermediate | Golfo Nuevo | Very clear water, with 8-20 m visibility in the record. White sea salmon and grouper, near slack. |
| Parque Nuevo | Artificial reef | To 12 m | Intermediate | Near town | Fish refuge with sea salmon and grouper. Mixed dive and shore-hunting context, so check traffic and permits. |
| Bahía Cracker | Rocky reef | To 15 m | Intermediate to advanced | North of Madryn | Cracker Derecha/Izquierda, with sea salmon, grouper and chernia. Avoid El Doradillo during whale months, June to December. |
Golfo Nuevo is sheltered and clean in the record, but tide is still Patagonian. Spring tide is about 4.9 m, so hunt near slack. West wind is offshore and often cleans the water.
The correct province is Chubut. The legal pack says marine licensing is provincial and Chubut issues a spearfishing licence marked as free. The Patagonian inland-water ban does not ban the sea. Respect the Valdés quota.
Sea salmon appears at Punta Este, Punta Cuevas, Punta Indio, Parque Nuevo and Bahía Cracker, with grouper, chernia and summer yellowtail. The strong Golfo Nuevo season is October to April.
Albatros, Folías, Urabain, Hu Shun Yu 809, Antonio Miralles, Goleta Emma and Río de Oro are dive parks or heritage in the record. Spearfishing goes to restingas and reefs.
Punta Este, Las Piedras, Punta Cuevas, Punta Indio, Parque Nuevo and Bahía Cracker are the restinga and reef references.
Golfo Nuevo can give 8-20 m in season, but tide, wind and E-SE sea decide the day.
Sea salmon, grouper, chernia and summer yellowtail for advanced divers. Respect licence, quotas and closed zones.
October to April is the strong Golfo Nuevo season in the record, with clear water and a broad temperature range.
Yes, and it is provincial. Puerto Madryn is Chubut.
