The Bay of Biscay (/ - /,; French: Golfe de Gascogne, Spanish: Golfo de Vizcaya, Basque: Bizkaiko Golkoa, Occitan: Golf de Gasconha, Breton: Pleg-mor Gwaskogn) is a gulf of the northeast Atlantic Ocean located south of the Celtic Sea. It lies along the western coast of France from Point Penmarc'h to the Spanish border, and the northern coast of Spain west to Cape Ortegal.
The south area of the Bay of Biscay washes over the northern coast of Spain and is known as the Cantabrian Sea.
The average depth is 1,744 m (5,722 ft) and the greatest depth is 4,735 m (15,535 ft).
The Bay of Biscay is named (for English speakers) after Biscay on the northern Spanish coast, probably standing for the western Basque districts (Biscay up to the early 19th century). Its name in other languages is:
- Asturian: Mar Cantábricu
- Basque: Bizkaiko golkoa
- Breton: pleg-mor Gwaskogn
- French: golfe de Gascogne (named after Gascony, France)
- Galician: golfo de Biscaia
- Occitan: golf de Gasconha
- Latin: Sinus Biscaiensis (Classical: Cantabricus, Cantabrorum, Gallaecum)
- Spanish: Golfo de Vizcaya (mar Cantábrico for the ocean area closer to the Spanish coast, the Cantabrian Sea)
- Irish: Bá na Bioscáine
- Dutch: Golf van Biskaje
Parts of the continental shelf extend far into the bay, resulting in fairly shallow waters in many areas and thus the rough seas for which the region is known. Large storms occur in the bay, especially during the winter months. The Bay of Biscay is home to some of the Atlantic Ocean's fiercest weather; abnormally high waves occur there. Up until recent years it was a regular occurrence for merchant vessels to founder in Biscay storms.
The main rivers that empty into the Bay of Biscay are Loire, Charente, Garonne, Dordogne, Adour, Nivelle, Bidasoa, Oiartzun, Urumea, Oria, Urola, Deba, Artibai, Lea, Oka, Nervión, Agüera, Asón, Miera, Pas, Saja, Nansa, Deva, Sella, Nalón, Navia, Esva, Eo, Landro and Sor.
In late spring and early summer a large fog triangle fills the southwestern half of the bay, covering just a few kilometres inland.
As winter begins, weather becomes severe. Depressions enter from the west very frequently and they either bounce north to the British Isles or they enter the Ebro Valley, dry out, and are finally reborn in the form of powerful thunderstorms as they reach the Mediterranean Sea. These depressions cause severe weather at sea and bring light though very constant rain to its shores (known as orballo, sirimiri, morrina, orbayu, orpin or calabobos). Sometimes powerful windstorms form if the pressure falls rapidly (Galernas), traveling along the Gulf Stream at great speed, resembling a hurricane and finally crashing in this bay with their maximum power, such as the Klaus storm.
The Gulf Stream enters the bay following the continental shelf's border anti-clockwise (the Rennell Current), keeping temperatures moderate all year long.
The southern end of the gulf is also called in Spanish "Mar Cantábrico" (Cantabrian Sea), from the Estaca de Bares, as far as the mouth of Adour river, but this name is not generally used in English. It was named by Romans in the 1st century BC as Sinus Cantabrorum (Bay of the Cantabri) and also, Mare Gallaecum (the Sea of the Galicians). On some medieval maps, the Bay of Biscay is marked as El Mar del los Vascos (the Basque Sea).
The Bay of Biscay has been the site of many famous naval engagements over the centuries. In 1592 the Spanish defeated an English fleet during the Battle of the Bay of Biscay. The Biscay campaign of June 1795 consisted of a series of manoeuvres and two battles fought between the British Channel Fleet and the French Atlantic Fleet off the southern coast of Brittany during the second year of the French Revolutionary Wars. USS Californian sank here after striking a naval mine on 22 June 1918. In 1920 SS Afrique sank after losing power and drifting into a reef in a storm with the loss of 575 lives. On 28 December 1943, the Battle of the Bay of Biscay was fought between HMS Glasgow, HMS Enterprise and a group of German destroyers as part of Operation Stonewall during World War II. U-667 sank on 25 August 1944 in position , when she struck a mine. All hands were lost.
On 12 April 1970, Soviet submarine K-8 sank in the Bay of Biscay due to a fire that crippled the submarine's nuclear reactors. An attempt to save the sub failed, resulting in the death of forty sailors and the loss of four nuclear torpedoes. Due to the great depth (15,000 ft or 4,600 m), no salvage operation was attempted.
Plaiaundi Ecology Park
The Plaiaundi Ecology Park is a 24 -hectare coastal wetland lying where the Bidasoa River meets the sea in the Bay of Biscay.The nature of Plaiaundi consists of a wide variety of flora (visitors view them mainly in the spring) and fauna (visitors with binoculars arrive all during the year, because of the birds migratory habits).This nature park contains a variety of birds, reptiles, mammals and insects.
The car ferries from Gijón to Nantes/Saint-Nazaire, Portsmouth to Bilbao and from Plymouth, Portsmouth and Poole to Santander provide one of the most convenient ways to see cetaceans in European waters. Often specialist groups take the ferries to hear more information. Volunteers and employees of ORCA regularly observe and monitor cetacean activity from the bridge of the ships on Brittany Ferries' Portsmouth to Santander route. Many species of whales and dolphins can be seen in this area. Most importantly, it is one of the few places in the world where the beaked whales, such as the Cuvier's beaked whale, have been observed relatively frequently. Biscay Dolphin Research monitored cetacean activity from the P&O Ferries cruiseferry Pride of Bilbao, on voyages from Portsmouth to Bilbao.
North Atlantic right whales, one of the most endangered whales, once came to the bay for feeding and probably for calving as well, but whaling activities by Basque people almost wiped them out sometime prior to the 1850s. The eastern population of this species are considered to be almost extinct, and there has been no record of right whales in the Bay of Biscay except for a pair in 1977 (possibly a mother and calf) at , and another pair in June 1980. Other records in the late 20th century include one off Galicia at in September 1977 reported by a whaling company and another one seen off the Iberian Peninsula.
The best areas to see the larger cetaceans are in the deep waters beyond the continental shelf, particularly over the Santander Canyon and Torrelavega Canyon in the south of the Bay.
The alga Colpomenia peregrina was introduced and first noticed in 1906 by oyster fishermen in the Bay of Biscay.

The Gulf Steam off Cape Hatteras, the Gulf of Alaska, the English Channel, and the Bay of Biscay are some of the other areas where storms and current combine to produce abnormally high, steep waves.
