Le verdict vient de sept facteurs de l'eau et de verrous de sécurité — pas de dix onglets. Y aller ou pas.
How we score the water
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.
01
Houle et mémoire de la vague
Hauteur, période et direction de la houle, plus le sillage des tempêtes récentes — une vieille tempête trouble encore l'eau, et le moteur s'en souvient.
02
Wind & gusts
Speed and gusts, hour by hour — wind speed and an onshore push chop the surface and cut visibility.
03
Tide phase
Timing and range of the tide, calibrated per coast — big spring tides pull the verdict toward caution.
04
Water temperature
Sea-surface temperature — sharply cold water vetoes a green verdict.
05
Currents & outflow
Direction and drift of the current — it pushes you, and it drags turbid coastal water across where you dive.
06
Rain runoff & air clarity
Rain muddies the water inshore through land runoff, while fog and haze cut visibility at the surface.
07
Coast shape & exposure
How the coast faces the swell — a sheltered cove keeps the water clean; an exposed, head-on point takes a penalty.
Safety gates
Thunderstorm forecast — an instant red, no exceptions.
An official warning (MeteoAlarm / IPMA) — yellow, or red for the higher ranks.
Missing input data — a would-be green is capped to yellow rather than overstated.
Strong disagreement between forecast models — a green day is pulled back to yellow.
Night hours — forced red; the window is closed after dark.
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.

Ce que c'est
Un instrument marin, on-y-va / on-n'y-va-pas pour la chasse en solo.
spearo.app réunit vent, vague, période de houle, visibilité, marées, température de l'eau et risque en un seul verdict — aller au spot ou non. Il calcule 7 jours à l'avance à partir de modèles marins ouverts (Open-Meteo, IPMA), sans inscription ni compte. Conçu pour la chasse sous-marine en solo depuis les rochers, où la moindre erreur coûte cher.
Now live: 1152 spots across 189 stretches of coast — mainland Portugal, Madeira and the Azores.

Sur le rocher
La prévision, c'est le plan. La décision se prend sur le rocher.
Les modèles fixent le créneau. Si vous entrez à l'eau, ça se lit seulement sur place : comptez les séries, observez le ressac à l'entrée. Dans le doute, vous n'entrez pas.
Points d'entrée
Où entrer depuis les rochers.
Entrées repérées, colorées selon le jour. La couleur, c'est l'état de la mer au spot, pas une garantie : le clapot et une entrée glissante, vous les jugez sur place.
Early morning in calm; never at dusk (night spearfishing is illegal and dangerous).
marée
Weak slack tide. Avoid the Arade ebb current, which pulls toward the shipping channel.
abri
Rocky cape on the east side of the Arade mouth, facing SSW. Sheltered from W wind by the cape itself, but fully open to S swell and surge.
danger
Heavy surge and shorebreak on the rocks, sinkholes/blowholes where the sea rushes under — entrapment risk. The busy Arade shipping channel is right there: ferries, cruise ships and fishing boats. High cliff, hard entry/exit.
accès
From the dirt track by the Ponta do Altar lighthouse, scramble down to the rock shelf (no steps, no beach). Awkward rock entry.
A known cliff-fishing spot, not documented as a dive entry. Scout from land first in dead calm; stay well clear of the shipping channel. Outside the concession, but very treacherous solo.
Molhe Leste (Praia da Rocha breakwater)Arade river-mouth jetty
fermé
in the headland's lee today — swell from the quarter/behind
créneau
Daylight only; night spearfishing is banned. Peak season = maximum boats, avoid.
marée
Strong tidal currents at the mouth; the ebb pulls into the channel. Slack water is essential.
abri
650 m breakwater at the east end of Praia da Rocha, guarding the Arade mouth. The inner (river) side is calm, the ocean side is open to S swell.
danger
Dominant danger is boat traffic — Ferragudo ferries, tour and fishing boats, cruise ships entering Portimão pass right by the jetty. Strong current at the mouth. Slippery, weed-covered breakwater blocks on the exit.
accès
Walk out along the jetty from the east end of Praia da Rocha by the Santa Catarina fort; enter off the breakwater blocks. No beach ramp on the ocean side.
Popular for line-fishing off the jetty, NOT a spearing spot: concessioned beach alongside (300 m rule in season) and a busy shipping channel. Land scout only — a genuine red zone because of boats.
Early morning for calm and clarity, before the afternoon sea breeze. Season June–October.
marée
Mid-to-high water: the arches and outer walls work best on a rising/full tide; low tide exposes tunnels and sharp rock.
abri
South-facing cove; the rock headlands and arches break W swell and shelter from W/NW wind. Open to direct S swell.
danger
Rockfall from undercut limestone cliffs — don't linger under the walls. Entrapment in the arches/fissures if swell builds. Sharp rock at the entry.
accès
Cliff stairways from the Três Castelos viewpoint (~120 steps); a rock tunnel links to Praia da Rocha. Enter off the sand, fin up at the water.
The best documented freedive site in Portimão: submerged limestone walls with sponges, moray, conger, grouper, octopus. Concessioned beach — spearfishing banned within 300 m in bathing season (Jun–Sep); off-season only and with a licence.
Mid-morning for visibility and before the sea breeze. Summer to early autumn.
marée
Mid water at the right-side reef; high water exposes fewer sharp rocks, low water reveals pools and the reef.
abri
South-facing, sheltered by red cliffs; the headland to the west blocks W wind and swell. Rocks and the pinnacle on the right (west) side give cover.
danger
Submerged rocks across the swim zone, especially in front of the standalone pinnacle — getting slammed onto rock on the exit if swell runs. Rockfall from the unstable red cliffs.
accès
Enter off the sand; best snorkelling is along the rocks on the right (west) side facing the sea. Parking and ramp from the Vau front.
Quieter than Rocha; the right-side rock reef holds fish. Concessioned beach — spearfishing banned within 300 m in bathing season; off-season only and with a licence.
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.

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».

✓Hand-gathering shellfish with NO gear — no licence; but if a speargun is on the dive, a spearfishing licence is required.
✓Night prohibited: spearfishing only in daylight (sunset→sunrise not allowed). Artificial light as a means of finding/attracting fish is banned — a torch for safety only.
✓Signalling buoy MANDATORY for spearfishing: buoy/float with an «Alfa» flag (red/orange/yellow, ≥8 L), no more than 30 m from the diver.
✓Spearfishing daily limit: fish + cephalopods — 15 kg (excluding the largest specimen). General rod-and-line recreational fishing — 10 kg.
Rules change. Before heading out, check with DGRM / ICNF / Capitania and the defeso table.
Protocole de sécurité
Sets: watch the wave trains ≥15 min before entering; Hmax ≈ 2×Hs, the wash can run 50 m past the foam line. A lull >10 min with period >12 s = a big set «overdue», do NOT enter; enter right after a full set passes and re-check at minute 30.
Exit FIRST: find your exit AND a backup before entering. At Cabo Raso/Arriba a 0.5 m rise in swell makes a boulder exit impossible — getting pinned/unable to climb out is the main killer here.
Headland rip: at Cabo Raso there is a permanent topographic rip regardless of the model — locate it, enter/exit on the windward side, never swim against it.
Cold: wetsuit per the SST chip; the first shiver = a metabolic surge and a drop in breath-hold → get out at the first steady shiver. Cap the session at 45–60 min below 15 °C.
Solo discipline: buoy up; tell someone the spot and exit time; conservative breath-hold (never push it in cold/murky/surfy water); visibility <3 m — don't enter.
Nortada (Jun–Sep): wind builds from midday — be out of the water by ~11:00; the chop builds — get out.
UV 11:00–15:00 (UVI ≥6): sunscreen and cover up on the surface interval.
Solo is a fundamental risk (hypoxic blackout with no buddy). Any doubt = No-go.
