Today — right on the edge — wave, wind and visibility.

Compiled by the spearo sea-state engine · How it works →
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.

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 mapThe cape itself: rock drop-off 8–30 m, scree and banks, seagrass around; bream, dentex, bass, leerfish passing in summer. Reached on foot along the coastal path, gear carried. Exposed to the south-east — the smallest SE swell makes it untenable. The Levant military zone is measured 5.5 km offshore.
Google MapsThe start of the corniche: red rock and scree 5–20 m, seagrass further out, shore entry off the beach. Bream, bass, octopus, dentex on the bank. Busy in summer — go early, and stay clear of the buoyed swimming zones.
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.
Cavalaire-sur-Mer has rock entry points such as Gigaro — pointe du Brouis (La Croix-Valmer) and Cap Lardier. The bay of Cavalaire itself is sand and seagrass: pleasant to swim, poor to hunt. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Long season (May–October), best June to September. Provence/Côte d'Azur: rocky calanques, clear water. The mistral is the deciding factor: on its days the exposed capes kick up — hide in the lee coves.
Mediterranean: ~13 °C in winter, ~24–26 °C in summer. 3–5 mm in summer. Rocky calanques give clear water; but after the mistral a sharp thermocline and upwelling set in — deeper water is colder and murkier.
Moderate: rocky calanques, clear water, but the mistral turns the exposed capes into a wall of waves. Beginner-friendly in the lee coves; in wind, hide.
