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.
Where to get in, where to hunt
Wind, wave and the swell windows — when to go and the best hours.
The day is picked above, in the hero. Here are that day's windows, the hour-by-hour map and the trends. Tap a window to break down the conditions.
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.
Now live: 1152 spots across 189 stretches of coast — mainland Portugal, Madeira and the Azores.

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.
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.

Google MapsSOLO 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.

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 Miramar is modest but real: scattered restingas, a town breakwater and green Atlantic water that only works in settled windows. It is not a clear-water Patagonia plan, and it is not as broad as Mar del Plata. The Restinga de Miramar, Restinga del Durazno and the breakwater can hold corvina, sea salmon and summer yellowtail. Legally, Miramar is Buenos Aires province, where spearfishing needs a careful provincial check before taking native fish.
These are small shore-rock options for calm days, not all-weather marks.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Restinga de Miramar | Scattered rocky reef | Shallow to medium | Intermediate | Shore entry after checking channels | Summer yellowtail is noted. Visibility is often green and short. |
| Restinga del Durazno | Rock south of town | 3-8 m in the local note | Intermediate | South Miramar beach access | A more defined rock option when the sea is low and settled. |
| Escollera de Miramar | Breakwater, pilings and rock | Low to medium | Cautious intermediate | Urban shore, avoid anglers | Corvina and sea salmon are mentioned, with line and wave-rebound hazards. |
Miramar works only when the sea is low, wind is weak and colour improves close to the rocks. Sudestada dirties the water and makes exits uncomfortable, so treat it as no-go. The tide is meso, but swell and sediment matter more. Buenos Aires is the correct province, and the spearfishing modality is not clearly published with its own quotas or sizes. Check Desarrollo Agrario or the provincial authority before harvesting; if unclear, dive only to scout.
It is usable but secondary, with small restingas and green water.
Durazno for defined rock, or the breakwater to check conditions.
Sudestada and dirty surf.
Summer yellowtail, corvina and sea salmon.
Buenos Aires. Verify the provincial rule before harvest.
