Shark Attacks in Ireland

Ireland has more shark species in its waters than most people would guess, from the basking sharks that cruise the Kerry and Donegal headlands each summer to the blue sharks and porbeagles that anglers chase off Cork. What it does not have is a history of sharks biting people. The SharkSider database lists two entries for the whole island, a century apart, and neither is a bather: one is a First World War sinking far out at sea, the other an angler bitten by the blue shark he had just hooked. This page sets out both, and explains why the record is so short.

In short

Ireland has 2 recorded shark incidents in the SharkSider database, spanning 1917 to 2018, 1 of them fatal. The fatal entry is the sinking of the ship Mariston, torpedoed 82 miles off Fastnet on 15 July 1917 with a single survivor, an entry the file records only as fatal and gives no further detail. The only bite is from 1 September 2018, when an angler off County Cork was bitten on the forearm by a 47-kilogram blue shark he had hooked, a provoked incident that he survived.

Nobody swimming, surfing, diving or paddling from an Irish beach has ever been entered in the database as bitten by a shark. The species that live here, basking sharks, blue sharks, porbeagles, tope and a range of small dogfish and catsharks, are plankton feeders, offshore hunters or bottom-dwellers that have no history of targeting people in cold north-east Atlantic water.

Why a shark-rich coast has almost no incidents

Ireland sits at the edge of the European continental shelf, washed on its western side by the North Atlantic Drift. The water is cool, between roughly 8 and 17 degrees through the year, rich in plankton and in the mackerel, herring and squid that feed on it. That productivity is why the island is one of the best places in Europe to see a basking shark, why charter boats out of Cork, Kerry and Clare catch and release blue sharks by the hundred every summer, and why porbeagles and tope patrol the reefs and sandbanks. Around thirty species have been recorded in Irish waters.

None of that translates into danger for people, for three reasons that the record makes plain. The first is temperature: the species most often involved in bites elsewhere, bull sharks, tiger sharks and the warm-water reef sharks, do not occur here at all, and the great white has never been confirmed in Irish waters despite decades of rumours. The second is behaviour: the basking shark is a filter feeder with no interest in anything larger than a copepod, and the blue shark and porbeagle are offshore fish-eaters that seldom come within sight of a beach. The third is exposure: Irish sea temperatures keep swimmers in wetsuits and close to shore, and the surf, sea-swimming and diving communities, though large and growing, spend their time in water where large sharks are simply absent.

The result is a database with two lines. One is a wartime maritime loss in which sharks appear only because they were seen around the survivors and the dead; the other is a hooked shark biting the hand that was unhooking it. Neither says anything about the safety of an Irish beach, and that is the honest reading of the record.

Where the two incidents happened, and the coasts that have none

Two entries do not make a map, so the list below places both events and then walks the coasts where people actually swim, surf and dive, with the record for each.

  • Off County Cork (September 2018)The only bite in the Irish record. On 1 September 2018 an angler was bitten on the forearm by a blue shark weighing 47 kilograms that he had hooked. The database classifies it as a provoked incident, the injury was to the forearm, and the man survived. It is the sole entry with an identified species.
  • 82 miles from Fastnet (July 1917)The only fatal entry. On 15 July 1917 the ship Mariston was torpedoed and sunk 82 miles off the Fastnet Rock, south-west of Cork; the database notes only that one person survived. No injury detail or species is recorded. It is a war loss at sea, not an attack.
  • Kerry: Dingle, the Blaskets and the SkelligsNo incident. This is the best basking-shark coast in the country, with animals of six metres and more feeding at the surface off Slea Head in May and June, and swimmers, kayakers and boat passengers have never been harmed by one.
  • Donegal and Malin HeadNothing recorded. Basking sharks gather off the north coast in early summer and blue sharks are caught offshore, while surfers use Bundoran and Rossnowlagh year-round without a single entry.
  • Clare and Achill IslandNo incident. Keem Bay on Achill was the site of a basking-shark fishery in the mid-twentieth century, and the cliffs of Clare draw sea-swimmers and divers; the record for both is blank.
  • Dublin Bay and the east coastNothing in the database. The Forty Foot, Seapoint and the beaches of Wicklow and Wexford host year-round sea swimming in the Irish Sea, where the sharks are small dogfish, smooth-hounds and the occasional tope.
  • The south-coast surf and swimming beachesNo incident at Inchydoney, Garrettstown, Tramore or any other beach in Cork and Waterford, the counties closest to both database entries. Both events happened well offshore, on boats.

Every recorded shark incident in Ireland

The stats and the table are produced directly from the SharkSider incident database, which draws on the International Shark Attack File, the Global Shark Attack File and verified local reports and is updated weekly. For Ireland there are two rows, and the decade chart shows one bar in the 1910s and one in the 2010s with nothing between them.

A few notes on how to read what is above. The 1917 entry is fatal because the sinking was fatal; the database includes it as a shark-related sea loss, as it does for a number of wartime losses in other countries, but it is not evidence that a shark killed anyone. The 2018 entry carries the label "provoked" because the shark was hooked and being handled when it bit, which is the standard classification for angling injuries. The activity column groups both under fishing and boats, the species column is empty for 1917 and reads blue shark for 2018, and no entry exists for any swimmer, surfer or diver. The record holds no names, ages or vessel details beyond the ship's name, and this page adds none.

The sharks of Irish waters and what they mean for the record

Blue shark. The only species named in the Irish database, and the shark that Irish anglers know best. Blue sharks arrive off the south and west coasts from June to October following warm water and shoals of mackerel, and the catch-and-release fishery out of Cork, Kerry and Clare handles hundreds a season. The 2018 bite happened exactly where the species meets people: in a boat, with a hooked and thrashing animal being brought alongside. A blue shark in the water beside a swimmer is close to unheard of in Ireland.

Basking shark. The second-largest fish in the world and the one most visitors hope to see. Basking sharks feed on plankton at the surface off Kerry, Clare, Mayo and Donegal in late spring and early summer and are entirely harmless; the only injuries ever linked to them anywhere are from boats striking or being struck by an animal. They appear in no Irish incident.

Porbeagle. A stocky, cold-water relative of the mako and the great white that hunts fish over reefs and banks off the west coast. It has the teeth and the size to injure a person but almost never comes near one, and there is no Irish record of it doing so.

Tope, smooth-hounds and dogfish. The sharks of the Irish Sea and the inshore bays: tope reach two metres but are shy fish-eaters, and the lesser-spotted dogfish and smooth-hound are small bottom feeders that anglers land from piers and beaches. None is capable of a serious bite.

Great white. Despite recurring headlines, no great white shark has ever been confirmed in Irish waters, and the database contains no entry attributing anything to one. The full guide to sharks in Ireland covers all the species and where and when to find them.

Staying safe in Irish waters, going by the record

The two Irish entries share one feature: both happened on boats, far from any beach. That makes the safety advice for Ireland unusual, because the risk it points to is not on the sand at all.

  • Handle hooked sharks with care. The one bite in the Irish record was inflicted by a blue shark being unhooked. Keep hands clear of the jaws, use a long-handled dehooker or cut the trace close to the hook, and let the skipper or an experienced deckhand control the fish alongside the boat.
  • Respect basking sharks from a distance. They are harmless, but a six-tonne fish and a kayak or a swimmer do not mix; stay well clear, do not touch, and never try to ride or grab one. Irish law and the Irish Whale and Dolphin Group's guidelines both ask for the same.
  • The real dangers on Irish beaches are cold water, rip currents and swell. Sea-swimmers and surfers should think about those before sharks; the drowning record for Ireland dwarfs its shark record by orders of magnitude.
  • Spearfishers and divers should keep speared fish off their body and in a catch bag, more for seals and conger eels than for sharks, but the habit is a good one anywhere.

If a shark ever did behave aggressively, the advice in our guide on how to survive a shark attack applies in cold water as much as warm: stay calm and vertical, keep the animal in sight, and move steadily back to the boat or shore.

Ireland in the European and world picture

Worldwide, the International Shark Attack File verifies around 60 to 80 unprovoked bites in a typical year, almost all of them from the United States, Australia, South Africa and a handful of tropical islands. Northern Europe barely registers. Ireland's two entries, one a wartime sinking and one a provoked angling bite, are typical of the region: Iceland, Norway and Sweden have records of the same character, a few historic maritime cases and almost nothing involving bathers. Move south to France, Spain and Portugal and the lists grow longer, and only in the Mediterranean and beyond do great whites and other large predators start to appear in them.

Measured against exposure, Ireland's position is even more reassuring: tens of thousands of people now swim in the sea year-round, tens of thousands more surf, and the bather count in the database is zero after more than a century of records. The shark attacks overview shows every country side by side.

Shark attack records around the North Atlantic

To the north, Iceland and Norway share Ireland's cold-water species and its near-empty record. To the south, France covers both the Atlantic and Mediterranean coasts, and Spain and Portugal mark where blue sharks and makos begin to appear in incident lists. Across the ocean, Canada shows what a similar cold-water coast looks like on the western side of the Atlantic. Every country we track is on the shark attacks overview.

Frequently asked questions

How many shark attacks have there been in Ireland?

The SharkSider database records 2 incidents for Ireland between 1917 and 2018, 1 of them fatal. The fatal case is the sinking of the ship Mariston off Fastnet in July 1917; the other is an angler bitten on the forearm by a hooked blue shark off County Cork in September 2018. No swimmer or surfer appears in the record.

When was the last shark attack in Ireland?

The most recent entry is from 1 September 2018, when a man fishing off County Cork was bitten on the forearm by a 47-kilogram blue shark he had hooked. It is classified as a provoked incident and he survived. It is the only shark bite ever recorded in Irish waters.

Has anyone ever been killed by a shark in Ireland?

The only fatal entry is not a bite. On 15 July 1917 the ship Mariston was torpedoed and sunk 82 miles from Fastnet, with a single survivor, and the record holds no further detail. The database includes it as a shark-related sea disaster; no person has been recorded killed by a shark bite in Ireland.

Is it safe to swim in the sea in Ireland?

Where sharks are the worry, the answer is yes. In more than a century of records no swimmer, surfer, diver or paddler has been bitten off an Irish beach. The genuine hazards are cold water, rip currents and swell. Both entries in the database happened on boats far offshore.

Are there great white sharks in Ireland?

No confirmed great white has ever been recorded in Irish waters, and the database attributes no incident to one. The large sharks that do occur, basking sharks, blue sharks and porbeagles, are either plankton feeders or offshore fish-eaters. Reports of great whites off Ireland have never been verified.

Which shark species has bitten someone in Ireland?

Only the blue shark, once. In September 2018 a 47-kilogram blue shark that had been hooked by an angler off County Cork bit him on the forearm while it was being handled. Blue sharks visit the south and west coasts each summer and are caught and released by charter boats.

Are basking sharks dangerous to swimmers in Ireland?

No. Basking sharks are filter feeders with tiny teeth that eat plankton, and they appear in no Irish incident. They are seen off Kerry, Clare, Mayo and Donegal from April to July. The sensible rule is to keep a respectful distance because of their size, not because of any threat.

Where in Ireland do shark incidents happen?

Both entries are off the south-west coast and both were at sea: one 82 miles from Fastnet in 1917, the other on a fishing boat off County Cork in 2018. No beach, bay or dive site anywhere in Ireland has an entry in the database.

Why are shark attacks so rare in Ireland?

The water is cold, the species that bite people elsewhere, such as bull and tiger sharks, do not live here, and Ireland's sharks are plankton feeders, offshore fish-hunters or small bottom-dwellers. Swimmers stay close to shore in cool water, so people and large sharks rarely share the same space.
