Today — sit it out — wave, wind and surge pounding.

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.

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: 1391 spots across 205 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 mapA beach filmed by a spearfishing team from northern Alagoas; shore entry, 2–6 m per the source and unmeasured. Watch out: the ZUMO and ZPRE zones of Carro Quebrado, from the Costa dos Corais management plan (ICMBio ordinance 308/2021), are right next door — check the limits.
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.
SpainRules 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.
Barra de Santo Antônio has rock entry points such as Praia do Carro Quebrado. Praia do Carro Quebrado is filmed by spearfishing teams, and the river bar is the base for offshore runs. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Best in the drier season (Sep–Mar); the Coral Coast's reef pools clear on calm, low-swell days.
Warm, ~26–28 °C — rashguard or 1.5 mm. Clear coral shelves; much of this coast is a protected APA with rules.
Beginner-friendly shallow reef, but heavily protected — check the APA Costa dos Corais no-take zones before you dive.
Yes — in Barra de Santo Antônio 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).
