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.

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.

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 mapLow slabs and sand off the Colonna monastery, 2.1 km east-southeast of the harbour, toward Bisceglie: entry from the Cristoforo Colombo promenade. Sea bream, sea bass and octopus on the steps. Open from north to east: with a tramontana the water dirties within half a day.
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.
Trani has rock entry points such as Scogliera di Colonna. The harbour under the cathedral is dock water, with boats and a narrow mouth. Below you'll find each spot (access, shelter and hazards) and today's forecast.
A long season on the Gargano and in the Salento, with often crystal-clear turquoise water (Mattinata, Otranto, Leuca). The Adriatic Salento opens with a westerly, the Ionian one with an easterly — there's almost always a side that works.
Warm: ~14–27 °C. A 3 mm suit in summer, 5 mm in the shoulder months. The white cliffs of the Gargano and the Salento give clear turquoise water, with quick drop-offs.
Intermediate: cliffs dropping into depth and very clear water (Otranto, Castro, Leuca). The Salento is exposed to opposite wind arcs — pick the day's sheltered side. Mind the set nets near the rock. Buoy always.
No — in Trani 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.
