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
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: 1152 spots across 189 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 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.
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».
National minimum sizes + a 150 g floor (in the table below); grouper 1/day. Spearfishing is closed all May (ΠΔ 373/1985).
Rules change, and the local Λιμεναρχείο (port authority) may impose local restrictions. Before heading out, check the current rules and the declared archaeological zones (ENALIA).
Spearfishing Cape Sounio is attractive because the water can be much cleaner than the central Athens coast, but the legal boundary matters first. Stay clear of the immediate Temple of Poseidon and cape frontage. The practical plan is to use nearby structure: Arsida for the Anavyssos lee, Simos Wreck for a shallow shore-access wreck, and roadside reef ground only when sea state and boundaries are clear.
Avoid selling the temple frontage as a target. These nearby options keep the plan practical while still requiring yellow caution, buoy use and boundary checks.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Arsida (Anavyssos) | Reef and cave | 25-35 m | Intermediate to advanced | Boat | NW-tucked from the cape and the main Sounio meltemi lee. |
| Simos Wreck | Shallow wreck | 9-18 m | More accessible | Shore | A rare shallow shore wreck near Anavyssos, but still needs clean exits and buoy discipline. |
| The parking lot | Rock and reef | 18-40 m | Intermediate | Shore or boat | Easy roadside entry on the Sounio coast, suitable only when the sea is settled and limits are clear. |
The cape is exposed to SE wind and swell, so the escape route is NW into Anavyssos Bay. Arsida is the named lee. The nearest listed camera is Porto Rafti, about 18 km NE, so it is only a broad sea-state clue. Greek legal baseline: May is totally banned (ΠΔ 373/1985); no licence since 2014; freediving-only; 5 kg/day. Keep clear of declared underwater archaeological zones.
No. Treat the immediate cape and temple frontage as off-limits because of the coastal archaeological zone.
No. Greece has required no recreational fishing licence since 2014, though the state sign-up should be checked.
Yes. The May national ban applies at Cape Sounio under ΠΔ 373/1985.
Arsida in Anavyssos Bay is the named NW-tucked lee option.
The area is described for sea bream, dentex, grouper and amberjack on points and deeper edges.
