Today — sit it out — wave, wind and surge pounding. 🌫 Murky all week after the storm — the water isn't settling

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».
Roscoff is a Channel spearfishing plan with one non-negotiable local rule: stay out of the navigable Île de Batz channel. Spearfishing is banned there because of strong currents and Brittany Ferries. The usable marks are outside that channel: Pointe de Bloscon, the Bay of Morlaix islets by boat, Pointe de Perharidy and Le Théven/Le Billou on the Santec side. The fish list is Atlantic/Channel, with bass, pollack, mullet, lobster, spider crab, conger and mackerel. France still requires RC insurance, breath-hold only practice, and the 2026 registration plus catch declaration regime.
Roscoff has good-looking kelp and rock, but the channel boundary is the first filter. The spots below carry no invented safety ratings. Local webcams show surface water at the port, panorama and Bloscon; there is no buoy station for France.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Pointe de Bloscon | Rocky headland east of the port | Rock and kelp shore ground | - | Shore | Bass, pollack, lobster and spider crab are the targets. Stay outside the Batz channel and separate from the ferry basin. |
| Îlots de la baie de Morlaix | Rocky islets and kelp | Rock and kelp fields | - | Boat | Lobster, spider crab and bass are the targets. Stay outside the navigable Batz channel. |
| Pointe de Perharidy | Rock-sand transition at Roscoff/Santec | Variable rock-sand ground | - | Shore |
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.
| Bass and lobster hold here. Visibility is variable. |
| Le Théven (Santec) | Tide-linked shore west of Roscoff | Rocky shore and edge ground | - | Shore | Le Théven and Le Billou are tied to mullet, lobster and bass, with hunting at the end of the ebb. |
Roscoff is Channel macrotidal. Webcams are available, but there is no live underwater visibility figure and no buoy station. Pointe de Perharidy has variable visibility. The practical filter is slack water and a position outside the Batz channel; do not turn a port camera into a promise for the Bay of Morlaix islets.
The answer is outside the channel only. Spearfishing is banned in the navigable channel of Île de Batz because of strong currents and Brittany Ferries. The Bay of Morlaix islets are boat ground outside the channel, and Pointe de Bloscon is also outside the Batz channel.
Roscoff has no month-by-month season. It has a macrotidal Channel regime and tide-dependent marks. Le Théven/Le Billou is specifically linked to the end of the ebb, and slack water is the safest timing cue. For species, keep to the Atlantic/Channel list: sea bass 42 cm, pollack 42 cm with max two per day, mullet 30 cm and mackerel 20 cm.
Yes. The France legal block says RC insurance is mandatory for spearfishing, either through a standalone policy or an FFESSM/FFPSA federation licence. It also says breath-hold only, no scuba or hookah, no night spearfishing, no loaded speargun out of the water, and from 10 Jan 2026 registration plus catch declaration.
Use Pointe de Bloscon, Bay of Morlaix islets outside the channel, Pointe de Perharidy and Le Théven/Le Billou. The Batz channel is excluded.
Only outside the navigable channel. Spearfishing is banned in the Île de Batz channel because of strong currents and ferry traffic.
The local spots name bass, pollack, mullet, lobster and spider crab. The Atlantic/Channel list also includes conger, mackerel, white seabream and black seabream.
There is no monthly season. Use macrotidal timing, slack water, and the end of the ebb at Le Théven/Le Billou.
No old-style spearfishing licence is required since 2009, but RC insurance is mandatory. From 10 Jan 2026, registration plus catch declaration applies.
