Compiled by the spearo sea-state engine
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 MapsLong reef with walls 9-10 m; the only true rock of the central Adriatic.
Google MapsRocky banks off Numana; the Sirocco murks it up, the offshore Bora clears it.
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».
Rules change. Before heading out, check with MASAF (registration) and the Guardia Costiera / Capitaneria di Porto; Sicily and Sardegna add regional tightening.
Sirolo-Numana has rock entry points such as Sassi Neri / Due Sorelle, Scoglio del Trave and Secca della Madonna. Spearfishing in Sirolo-Numana: sea forecast and shore-entry spots. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Mostly summer, and only on the Conero rock (Sirolo–Numana): the rest is sand and murk. The scirocco (SE) shuts visibility at once, the offshore bora (NE) often cleans it. In summer the 500 m bathing ban pushes you to dawn and dusk.
~12–26 °C depending on season. A 3–5 mm suit in summer, 5 mm in the shoulder months. On the Conero the water is relatively clear for the Adriatic; the scirocco clouds it fast.
Demanding for visibility reasons: only the Conero holds up, the rest is sand and murk. You have to catch the good window (offshore bora that cleans). Summer 500 m bathing ban: dawn or dusk. Buoy always.
No — in Sirolo-Numana 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.
