Compiled by the spearo sea-state engine
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.
Cameras, map and reference — to hand as you come up.
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.
Quequén has rock entry points such as Escollera Este de Quequén and Bahía de los Vientos (fondos rocosos). East side of the Río Quequén mouth: a harbour jetty with structure, but turbid in the river discharge. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Summer (Dec–Mar) — the only warm window; sudestada and an open shelf. Spearfishing grey — check.
Summer 18–22 °C — 5 mm suit; winter 8–12 °C — 7 mm. Open shelf, sudestada.
Hard: open shelf, sudestada, grey spearfishing law. Plan for summer and offshore wind.
In Quequén (Argentina) the rules are PROVINCIAL. Río Negro (Ley 5.706/2024): apnea only, no night. Chubut: free permit + Valdés cupo. In Buenos Aires spearfishing is NOT regulated (grey zone) — we don't promote hunting natives until the province text is verified. All National Parks (Islote Lobos, Monte León, PN Tierra del Fuego) and Península Valdés = no-take. See the guide.
