Today — sit it out — wave, wind and surge pounding. 💧 Water should clear by Tuesday (~2d)

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.

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.

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».
Spearfishing in Calvi starts with legality. The Haute-Corse cantonnement closes the bay and port cantonnement as closed to spearfishing, fishing and diving, so the usable plan is west, around Revellata, after checking the DIRM chart. Revellata gives granite, drop-offs and 15 to 25 m visibility in good water, with dentex, bass, bream and amberjack. A sea forecast Calvi check should focus on the southwest libeccio, which hits the peninsula directly. France requires insurance, apnea only and daylight hunting.
Treat every entry as outside the closed bay-port zone and verify the boundary before entering.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Revellata north side | Granite peninsula | 5 to 25 m | Intermediate to advanced | Shore or boat | Fish-rich drop-offs with dentex, bass and amberjack; libeccio is head-on. |
| Revellata lighthouse point | Point and drop-offs | 6 to 25 m | Advanced | Shore or boat | Dentex and amberjack ground. Brown meagre is protected, observe only. |
| Punta Spano | Islets and reefs | 3 to 25 m | Intermediate | Shore entry | Bream on reefs; busy site, better early or late. |
The Mediterranean tide is small; southwest wind is the deciding factor. Livelier libeccio can make Revellata exits rough even if the bay looks manageable. For freediving Calvi, use a calm morning, stay outside the cantonnement, carry insurance, hunt breath-hold only and remember that grouper and brown meagre are protected in the French Mediterranean.
Rules change. Exact distances from beaches/ports and seasonal closures are set by the local préfecture maritime — check its arrêté and the DIRM/OFB zone map before heading out.
No. The Haute-Corse cantonnement closes the bay and port cantonnement as closed.
No French spearfishing licence or declaration is required, but insurance is mandatory.
The southwest libeccio, which hits Revellata directly.
Dentex, bass, bream and amberjack; brown meagre may be seen but is protected.
No. Apnea only.
