Oulu (/ˈoʊluː/ OH-loo,[8][9] Finnish: [ˈou̯lu] ⓘ; Swedish: Uleåborg [ʉːlɛɔˈbɔrj] ⓘ) is a city, municipality and a seaside resort of about 210,000 inhabitants[4] in the region of North Ostrobothnia, Finland. It is the most populous city in northern Finland and the fifth most populous in the country after: Helsinki, Espoo, Tampere and Vantaa, and the fourth largest urban area in the country after Helsinki, Tampere and Turku. Oulu's neighbouring municipalities are: Hailuoto, Ii, Kempele, Liminka, Lumijoki, Muhos, Pudasjärvi, Tyrnävä and Utajärvi.

Oulu is one of the largest cities in the world for its latitude. It is the fourth northernmost city in the world with over 100,000 inhabitants, with the three others located in Russia.

Due to its large population and geopolitically economic and cultural-historical location, Oulu has been called the "capital of Northern Finland".[1] Oulu is also considered one of Europe's "living labs", where residents experiment with new technology (such as NFC tags and ubi-screens) on a community-wide scale.[10] Despite only ranking in the top 2% universities,[11] the University of Oulu is regionally known in the field of information technology.[12][13][14] Oulu has also been very successful in recent urban image surveys; in a study published by the Finnish Economic Survey in 2008, it received the best ranking of large cities in image ratings across the country, including ratings from respondents in all provinces.[15] In the 2023 T-Media survey, Oulu was tied with Kuopio as the second most attractive city in Finland, while Tampere taking first place.[16]

Once known for wood tar and salmon, Oulu has evolved into a major high-tech centre, particularly in IT and wellness technology. Other prominent industries include wood refining, chemicals, pharmaceuticals, paper, and steel.

Oulu has been chosen as the European Capital of Culture for 2026.[17][18]

Etymology

The city is named after the river Oulujoki, which originates in the lake Oulujärvi. There have been a number of other theories for the origin of the name Oulu. One possible source is a word in the Sami language meaning 'flood water', but there are other suggestions. At minimum, the structure of the word requires that, if originally given by speakers of a Uralic language, the name must be a derivative. In all likelihood, it also predates Finnish settlement and is thus a loanword from one of the now-extinct Saami languages once spoken in the area.

The most probable theory is that the name derives from the Finnish dialectal word oulu, meaning "floodwater", which is related to e.g. Southern Sami åulo, meaning "melted snow", åulot meaning "thaw" (of unknown ultimate origin). Two other word families have also been speculated to be related. The first is seen in the Northern Savo dialectal word uula and its Sami counterpart oalli, both meaning "river channel". The second is the Uralic root reconstructed as *uwa, meaning "river bed" (reflected as vuo in modern Finnish, also in derivatives such as vuolas "heavy-flowing"). To either of these roots, some Sami variety would have to be assumed having added further derivational suffixes.[19]

History

Drawing of central Oulu from the 19th century

Oulu is situated by the Gulf of Bothnia, at the mouth of river Oulujoki, which is an ancient trading site. The city proper was founded on 8 April 1605 by King Charles IX of Sweden,[20] opposite the fort built on the island of Linnansaari. This took place after favourable peace settlements with Russia, which removed the threat of attack via the main east–west waterway, the river Oulu. The surrounding areas were populated much earlier. Oulu was the capital of the Province of Oulu from 1776 to 2009.

In 1822, a major fire destroyed much of the city. The architect Carl Ludvig Engel, chiefly known for the neoclassical (empire style) buildings around Helsinki Senate Square, was enlisted to provide the plan for its rebuilding. With minor changes, this plan remains the basis for the layout of Oulu's town center. The Oulu Cathedral was built in 1832 to his designs, with the spire being finished in 1844. During the Åland War, part of the Crimean War, Oulu's harbour was raided by the British fleet, who destroyed ships and burned tar houses, leading to international criticism.

Geography

Satellite image of the Oulu region.

Oulu is located in northern Finland, a considerable distance from the other cities in the country. It is located 607 kilometres (377 mi) north of the capital city Helsinki. Mainland Finland's northernmost and southernmost points are roughly equidistant from Oulu. Oulu's coast sits at the Bothnian Bay (Perämeri in Finnish) and the Swedish mainland is about 180 km directly west across the Bothnian Bay. From the center of Oulu in the direction of Oulunsalo, there is Kempeleenlahti, a smaller but wide, meadow-belted bay,[21] and part of it has been listed as a nature conservation area.[22] The nearby island Hailuoto is just off the coast, 53 kilometres (33 mi) away in the Bothnian Bay. Along the coast to the southwest, about 75 kilometres (47 mi) of Oulu is Raahe (Brahestad), known for its historic wooden town, and about 130 kilometres (81 mi) of Oulu is Kalajoki, known for its popular sandy beaches.

Subdivisions

The map of Oulu from 1886.

Oulu is divided into 106 city districts. The largest of these are Haukipudas, Oulunsalo, Kaakkuri, Ritaharju, Tuira, and Kello.

The municipality of Ylikiiminki was merged with the city of Oulu on 1 January 2009. Oulu and the municipalities of Haukipudas, Kiiminki, Oulunsalo, and Yli-Ii were merged on 1 January 2013.[23]

Climate

Oulu has a subarctic continental climate (Köppen Dfc), to within 0.4 °C of a Dfb (humid continental climate). It is the largest Finnish city entirely in this climatic zone as well as one of the largest such in the world. The typical features are cold and snowy winters with short and mild summers.[24][25] Average annual temperature is 3.3 °C (37.9 °F). The average annual precipitation is 477 mm (18.78 in) falling 105 days per year, mostly in late summer and fall. The warmest temperature ever recorded in Oulu was 33.3 °C (91.9 °F) in July 1957,[26] while the coldest temperature on record was −41.5 °C (−42.7 °F) in February 1966.[27]

Due to Oulu's far northern location, and its frequent overcast skies, it only sees on average 15 minutes of sunlight per day in December. During the winter solstice days only last 3 hours and 34 minutes with the sun rising 1.9 degrees over the horizon. On the other hand, during the summer solstice days last 22 hours and 3 minutes, with the sun dipping 1 degree below the horizon. This gives Oulu white nights during the summer.[28]

On June 21, 2021, Oulu was struck by the Ahti thunderstorm, causing flooding and fall of trees with the wind blowing at more than 30 meters per second.[29] The storm is known to have killed one person and injured two people.[30][31]

Transport

Finnair is one of the main operators of the Oulu airport with regular flights to Helsinki.

Oulu is served by Oulu Airport, the second largest airport in Finland by passenger volume. It is located 15 kilometres (9 mi) south-west of the city centre.

The Port of Oulu is one of the busiest harbours on the Bothnian Bay. It includes four separate harbour areas: Vihreäsaari oil and bulk docks, Nuottasaari docks and Oritkari docks. There is also a ferry service in Oulu, which is mostly used between Oulunsalo and the Hailuoto Island.[44]

The shortest travel time from Oulu railway station to Helsinki Central railway station is 5 h 34 min, operated by VR. Other destinations include Kolari, Rovaniemi, Seinäjoki and Tampere.

The most important road in Oulu is Highway 4 (E8/E75) that runs from Helsinki to Utsjoki via Lahti, Jyväskylä, Oulu, Kemi and Rovaniemi. Other highways running to and from Oulu are Highway 20 to Kuusamo and Highway 22 to Kajaani.[45]

Oulu Bus Station

Oulu is notable for its transportation network dedicated to non-motor vehicular traffic, including pedestrians and bicycles (termed "light" traffic in Finland). In 2022, the city contained more than 950 kilometres (590 mi) of pathways and more than 300 underpasses and bridges devoted exclusively to pedestrian and bicycle traffic. The network is used year-round. The ratio of walking and cycling traffic pathways to residents is the highest in Finland and the cycling mode share is 20 percent.[46][47][48]

Parked bicycles on Kirkkokatu Street in January

Even in winter, bicycle commuting remains strong in Oulu, in spite of the cold, dark, and snow. About 12% of winter trips are by bicycle, and about half of trips to school or university are. The city has a robust system for keeping bike paths maintained and clear of snow, and bike paths and lanes are plowed before roadways to encourage such human-scale winter transit in the city where 12% already do so.[49] The Winter Cycling Federation was founded in Oulu in 2013, and the first Winter Cycling Congress was held there.[50]

In 2015, a large underground parking facility, Kivisydän (Stone Heart), opened in the city center directly beneath main shopping streets. The network of parallel roads for cars and pedestrians was drilled in the rock at the depth of 30 meters (98 ft). The parking facility includes two ramps, 900 visitor parking lots (expandable to 1500), six access points to the ground served by 19 elevators (expandable to nine and 25), a service facility for commercial delivery vehicles, and ubi-screens that guide the driver to the selected ground access point and help locate the parked car by its license number.[51][52]

Solar power

In 2015, the Kaleva Media printing plant in Oulu became the most powerful photovoltaic solar plant in Finland, with 1,604 solar photovoltaic (PV) units on its roof. Although the city of Oulu, located near the Arctic Circle, has only two hours of weak sunlight in December, the photovoltaic cells work almost around the clock in the summer. The cold climate means the PV panels can get up to a 25% boost per hour, as they don't overheat.[53]

Because the sun is quite low in the sky at this latitude, vertical PV installations are popular on the sides of buildings. These solar walls also capture light reflected from snow.[53]

Snow is not necessarily cleared from rooftop solar installations.[53]

The local utility, Oulun Energia, is owned by the city of Oulu. The energy mix it receives from the Nordic-wide grid includes wood pellets, waste incineration, bioenergy, hydro-electric, geothermal, wind, nuclear, peat, natural gas and coal.[53]
