Spearfishing on Atlantic Europe's coasts
Explainer · Last reviewed 2026-08-25
The same countries as the Mediterranean tradition, facing an ocean instead of a sea — and the swell, tidal range and cold that come with it change the diving completely.
Safety
Cliffs and rock platforms — Can cause serious injury or death
Entry and exit over swell-washed rock is where most incidents on exposed Atlantic coast occur. A swell that has built during a session can make the planned exit unusable, leaving a cold and tired diver committed to a shoreline that is breaking.
What reduces it: Choosing and checking the exit before entering, identifying an alternative, watching for several minutes to see the sets rather than the lulls, treating rising swell as a reason to leave immediately, and never diving alone on this kind of ground.
Portugal, Galicia and the Spanish north coast, the French Atlantic and Biscay coasts, and the Atlantic seaboard of Morocco share something that is easy to miss: they are dived by the same national communities that produced Mediterranean spearfishing, in an environment that has almost nothing in common with it.
WHAT THE OCEAN ADDS. Groundswell generated thousands of kilometres away arrives regardless of local wind, which means a windless day can be undiveable and a windy one can be fine. Tidal range is large — several metres over much of the coast — and tidal streams around headlands and estuary mouths are strong. Water temperature is markedly lower than the Mediterranean at the same latitude because of the ocean circulation and, along Iberia, seasonal upwelling that brings cold nutrient-rich water to the surface.
THE UPWELLING IS THE KEY FACT. It is why this coast is biologically rich, why the water is often green rather than blue, and why visibility swings from excellent to poor without any change in the weather a diver can see. It also produces sharp temperature layering: a diver can pass through several degrees within a few metres of depth.
THE GROUND. Exposed rock platforms, reefs taking the full force of the swell, kelp and other large algae in the north, sandy bays between headlands, and estuaries carrying freshwater and sediment. Entry and exit over swell-washed rock is the defining hazard of the coast and the reason most incidents here happen at the water's edge rather than at depth.
THE FISH. A genuine mixture — Mediterranean species at the southern end, northern species at the northern end, and a shared middle of bass, seabream, meagre, pollack, wrasse and mullet, with pelagic visitors seasonally.
THE CULTURE. Portugal in particular has a long and serious competitive spearfishing tradition and has produced a great deal of the sport's technical development. The diving is regarded within the wider European community as physically demanding, which is a fair description: swell, cold, current and long shore swims in combination.
Swell, and why it is the first question here
On this coast the swell forecast is not one input among several. It is usually the decision.
GROUNDSWELL AND WINDSEA ARE DIFFERENT THINGS. A long-period groundswell of modest height carries far more energy onto a rock platform than a short-period windsea of the same height, and it arrives in sets with lulls between them. A diver who judges the water by watching for two minutes has not seen the set that will arrive in twelve.
THE EXIT IS THE CONSTRAINT, NOT THE ENTRY. Getting into the water off rock during a lull is straightforward. Getting out onto the same rock, tired, cold, carrying a gun, a float and possibly fish, on a swell that has built during the session, is the situation that produces the incidents. The rule everywhere on exposed coast is to plan the exit first, identify an alternative, and treat a rising swell as a reason to leave early rather than as a reason to hurry.
SURGE CONTINUES UNDERWATER. Close to reefs and in gullies the water moves back and forth with the swell, and it moves a diver with it. Near rock, in surge, a diver is not fully in control of their position, which is a hazard in its own right and a reason not to work tight ground on a big day.
This is the same hazard that dominates rock fishing on exposed coasts anywhere, and the water-safety guidance developed for that transfers directly.

One country, two seas, two sets of rules
Spain and France each face both the Mediterranean and the Atlantic, and their rules are not necessarily identical on both coasts. Regional administrations add their own layers, and protected areas add more.
That produces a situation worth naming explicitly, because it is a common way for a visiting diver to get into trouble honestly: knowing the rules for a country is not the same as knowing the rules for a coast, and knowing the rules for a coast is not the same as knowing the rules for a site.
Spearfishing rules here vary by country, by region, by site and by species, and they change. Nothing on this page states what is currently permitted anywhere. Check the current position with the national fisheries or marine authority, the protected-area manager where one applies, and a local club or federation, who will usually know the site-level detail a national statement does not carry.

Check the rules before you fish
Fishing laws, bylaws, access rules, seasons, bait restrictions and permitted methods vary by location and can change. Check the current rules from the relevant authority and the water you intend to fish before fishing.
Check with:
- Current national or regional law for where you are fishing
- Current local bylaws
- The relevant fisheries authority
- The landowner, club or fishery whose water it is
- Any restrictions specific to the species or the method you intend to use
