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».
Rules change. Before heading out, check with MASAF (registration) and the Guardia Costiera / Capitaneria di Porto; Sicily and Sardegna add regional tightening.
Spearfishing in Carloforte / Sant'Antioco depends on choosing the right side of the islands. Capo Sandalo is an exposed western cliff and drop in the Mistral line. La Punta / Punta delle Colonne offers relative shelter on westerly winds. Capo Sperone on Sant'Antioco is granite to the south, exposed to S/SW. The data shows no local plume or buoy. Pick the return route before loading.
All listed spots are yellow, medium solo-severity shore entries and are not marked protected for these entries.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Capo Sandalo | Western cliff and rockfall | Wall/drop; no number listed | Intermediate to advanced after Mistral settles | Shore entry; route not specified | Amberjack and dentex, but directly exposed to the Mistral. |
| La Punta / Punta delle Colonne | Rocky columns to the east | Rock columns; no numeric depth | Intermediate; relative west-wind shelter | Shore entry near the columns | Sea bream, with shelter when westerlies are the issue. |
| Capo Sperone / Sant'Antioco | Southern granite cape | Granite coast; no number listed | Intermediate; watch S/SW exposure | Southern shore entry | Gilthead and dentex; exposed to south and southwest. |
If 315 degrees is active, Capo Sandalo is the wrong idea. La Punta can be useful when west wind is the problem but the sea has settled. Capo Sperone needs a different filter: avoid south and southwest swell. Mediterranean tide is secondary.
No paid license, but the free MASAF declaration via SIAN/SPID is required.
No. The Sardegna rules set a full grouper ban.
No. Italy allows spearfishing only while freediving and from age 16.
Keep 500 m from beaches with bathers and 100 m from fixed gear, set nets and anchored vessels outside ports.
Use about 5 kg per person, or one heavier fish, then check current decrees and Sardegna size limits.
