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

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.
Leave your email — and the moment a window opens at Naples, we'll send the go / no-go verdict. Email is all we need.

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: 3016 spots across 406 stretches of coast — mainland Portugal, Madeira and the Azores.
See all spotsRelief and bottom type, tides, and the depths of each spot.
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 isolated rock off Capo Posillipo, 90 m out from the shore: a tuff wall, boulders and coarse sand, the bottom dropping to 12-15 m. Get in from the rocks below the road and swim out to it. This is OUTSIDE the Gaiola underwater park, whose boundary is just over a kilometre west: you may hunt here, at Marechiaro and Gaiola you may not.
Google MapsUnder the Posillipo cliff, off the Monache beach: tuff, fallen boulders and patchy posidonia down to 8-10 m. Entry from the rocks beside the lido, the mark sits 55 m out from the shoreline. Sea bream and octopus; boats and hydrofoils run past toward Mergellina, float mandatory.
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.
Naples has rock entry points such as Spiaggia delle Monache and Scoglio Pietra Salata. The only real rock in the city is Posillipo: tuff cliffs, fallen boulders and patchy posidonia down to 8–10 m. Below you'll find each spot (access, shelter and hazards) and today's forecast.
A long season: the Cilento (Palinuro, Acciaroli) and the Amalfi coast east of Punta Campanella give warm, clear water from late spring to autumn, and beyond on sheltered days. Work the lee side between the headlands.
Warm: ~14–27 °C, among the mildest on the mainland. A 3 mm suit in summer, 5 mm in the shoulder months. In the Cilento visibility is often excellent.
Accessible in the Cilento: warm, clear, sheltered water between the headlands, good for building water time on calm days. Mind the summer boat traffic on the Amalfi coast. Buoy always.
No — in Naples there is no paid licence; a free MASAF declaration is mandatory (the recreational sea-fishing communication, online via SIAN/SPID, renewed each year), which is not a «licence». Breath-hold only (no scuba), with a marker buoy and no selling the catch. See the guide.
Rules change. Before heading out, check with MASAF (registration) and the Guardia Costiera / Capitaneria di Porto; Sicily and Sardegna add regional tightening.
