Today — sit it out — wave, wind and surge pounding. 💧 Water should clear by Tuesday (~3d)

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
Leave your email — and the moment a window opens at São Gonçalo do Amarante, we'll send the go / no-go verdict. Email is all we need.

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: 3016 spots across 406 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.
Open the seafloor mapShore entry on Praia do Pecém, 3–9 m as reported and not independently measured. Watch out: the Pecém port terminal lies about 2 km to the east, with a manoeuvring and port security area — check the limits before you get in.
Google MapsThe sandstone reefs of Taíba, with shore entry. A spearfishing account devoted solely to this beach backs the practice. Depth of 3–10 m per the source, with no seabed survey of our own.

The full spot briefing is part of the subscription: entry, bottom, hazards, tide window.
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.
Rules change and vary by state. Before heading out, check on gov.br (recreational licence, MPA) and the state closed seasons/sizes; apnea only, goliath grouper is banned.
São Gonçalo do Amarante has rock entry points such as Recifes da Taíba, Praia do Pecém and Naufrágio Baron Dechmont (Navio do Pecém). Ten kilometres of Taíba beach with sandstone reefs and shore entry, plus the Navio do Pecém — a steam freighter torpedoed by U-507 in 1943, now 22–34 m: an advanced boat dive. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Driest and calmest Jul–Dec; strong trade winds chop the surface much of the year, so pick the early-morning lulls.
Warm, ~26–28 °C — rashguard. Wind chop and river runoff cut clarity; best on the calm mornings on the reefs.
Moderate: warm reefs but persistent trade winds — a wind-aware, early-start coast rather than an all-day one.
Yes — in São Gonçalo do Amarante you need the Licença de Pesca Amadora (gov.br portal; the category follows boat use, per the MPA: «desembarcada» R$ 20/yr when you enter from shore, «embarcada» R$ 60/yr with a boat — Portaria 616/2022 itself sets no categories; 65+/pensioners exempt). Breath-hold only (no scuba tank — art. 4º §3º), licence on you (art. 17); take home at most 15 kg + 1 fish and never filleted or headless (arts. 8º and 12); don't sell the catch (art. 6º). A marker buoy is mandatory in Santa Catarina (IN MMA 21/2005, art. 5º) — there is no federal buoy rule. Goliath grouper (mero) is full no-take, dusky grouper has a 1 Nov–28 Feb closed season, badejo-mira and peroá close on 25/10/2026 (Portaria GM/MMA 1.666/2026, art. 12) and taking lobster while diving is banned all year (Portaria SAP/MAPA 221/2021, art. 6º III).
