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.

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.

Google MapsCameras, map and reference — to hand as you come up.
Check the cam BEFORE you leave. Foam, brown/green murk, or waves washing the entry rocks = No-go. At night/in fog the cam is useless — treat it as «unknown», NOT «green».

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 change. Exact distances from beaches/ports and seasonal closures are set by the local préfecture maritime — check its arrêté and the DIRM/OFB zone map before heading out.
Noirmoutier has rock entry points such as Pointe de L'Herbaudière, Bois de la Chaise / Pointe des Dames and Pointe du Devin. A low, sandy island, but two rocky bits are worth the trip: the Pointe de L'Herbaudière in the NW and the more sheltered Bois de la Chaise / Pointe des Dames in the east. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Summer (June–October) — the steadiest. Pays de la Loire: islands (Yeu, Noirmoutier) and meso-tides; after rain the water clouds with river runoff — give it a day or two to clear.
Atlantic: ~10 °C in winter, ~19–20 °C in summer. 5–7 mm. The Loire runoff clouds the water after rain — best visibility is at the offshore spots of Yeu/Noirmoutier.
Moderate: islands and meso-tides, water clouds after rain. Suits confident beginners on calm summer days; aim for the offshore spots for visibility.
