Köppen climate classification types of Finland

The climate of Finland is influenced most by its latitude: Finland is located between 60 and 70 N. Because of Finland's northern location, winter is the longest season. Only on the south coast and in the southwest is summer as long as winter. On average, winter lasts from early January to late February in the outermost islands in the archipelago and the warmest locations along the southwestern coast – notably in Hanko – and from early October to mid May in the most elevated locations, such as northwestern Lapland and the lowest valleys in northeastern Lapland. This means that southern portions of the country are snow-covered about three to four months of the year, and the northern for about seven months. The long winter causes about half of the annual 500 to 600 millimetres (19.7 to 23.6 in) precipitation in the north to fall as snow. Precipitation in the south amounts to about 600 to 700 millimetres (23.6 to 27.6 in) annually. Like that of the north, it occurs all through the year, though not so much of it is snow. [1]

In Köppen climate classification Finland belongs to the Df group (continental subarctic or boreal climates). The southern coast is Dfb (humid continental mild summer, wet all year), and the rest of the country is Dfc (subarctic with cool summer, wet all year). [2] [3]

The climate of Finland has characteristics of both maritime and continental climate. The Atlantic Ocean to the west and the Eurasian continent to the east interact to modify the climate of the country. The warm waters of the Gulf Stream and the North Atlantic Drift Current, which continuously warm the region, play a big role in the climate of Norway, Sweden and Finland; if it weren't for these currents, the winters in Scandinavia and Fennoscandia would be much colder. Westerly winds bring the warm air currents into the Baltic areas and to the country's shores, moderating winter temperatures, especially in the south and southwest in cities like Helsinki and Turku where winter highs tend to be between 0 and 5 °C (32 and 41 °F) but a cold snap like the one that occurred in mid-January 2016 can cause temperatures to plunge well below −20 °C (−4 °F). These winds, because of clouds associated with weather systems accompanying the westerlies, also decrease the amount of sunshine received during the summer. By contrast, the continental high pressure system situated over the Eurasian continent counteracts the maritime influences, occasionally causing severe winters and high temperatures in the summer.

Temperature

The warmest annual average temperature in Southwestern Finland is 6.5 °C (43.7 °F). From there the temperature decreases gradually towards north and east. The Suomenselkä and Maanselkä drainage divides rise higher than the surrounding areas, and the climate there is cooler than at same latitudes elsewhere in Finland. [4] The Barents Sea between Finland and the North Pole is open even in winter, so northerly airflows are not as cold as in Siberia or Alaska. [5]

The highest temperature ever recorded is 37.2 °C (99.0 °F) (Liperi, July 29, 2010). [6] The lowest, −51.5 °C (−60.7 °F) (Kittilä, January 28, 1999). The annual average temperature is relatively high in the southwestern part of the country (5.0 to 7.5 °C or 41.0 to 45.5 °F), with quite mild winters and warm summers, and low in the northeastern part of Lapland (Finland) (0 to −4 °C or 32 to 25 °F).

Wind

The most common wind direction in Finland is from southwest, but the low pressure areas typical for these latitudes cause great variations in wind speed and direction. [1]

Storm, defined as at least one Finnish coastal station reporting at least 21 m/s as a 10-minutes average wind speed, is observed on Finnish seas on average 19 days a year. Strong winds are most frequent between October and January. [23]

Snow

The first snow cover is observed on average in September in Lapland, and in November in Southern and western areas. Permanent snow cover time starts typically around Christmas in the Southwestern corner, but before mid-November in most of Lapland. The maximum snow depth is usually found around March. [24]

Snow and supercooled droplets can accumulate in tree crowns and cause damage to trees. The trunks of pine trees can break under the weight of a snow-loaded crown, and deciduous trees can bend permanently. The snow load of a tree is typically 100–150 kg per one meter tree trunk, but the heaviest measured snow load of a spruce was over 3000 kilograms. [25]

Snowmelt contributes to spring floods. In north, the peak flow of rivers always happens in spring, in the south 70–80% of floods happen in spring. In the south, maximum flow happens in mid-April, in the north, in mid-May. [26]

It is predicted that as the Barents Sea gets less frozen in the coming winters and it becomes thus "Atlantified" additional evaporation will increase future snowfalls in Finland and much of continental Europe. [27]

Annual mean precipitation (%) in Finland in 2000–2085 compared to the average values in 1971–2000, under different Representative Concentration Pathways scenarios.
Climate change has far reaching impacts on the natural environment and people of Finland. Finland was among the top five greenhouse gas emitters in 2001, on a per capita basis. [28] Emissions increased to 58.8 million tonnes in 2016. [29] Finland needs to triple its current cuts to emissions in order to be carbon neutral by 2035. [30] Finland relies on coal and peat for its energy, but plans to phase out coal by 2029. [31] Finland has a target of carbon neutrality by the year 2035 without carbon credits. The policies include nature conservation, more investments in trains, changes in taxation and more sustainable wood burning. [32] After 2035 Finland will be carbon negative, meaning soaking more carbon than emitting. [33]

<span class="mw-page-title-main">Geography of Finland</span>

The geography of Finland is characterized by its northern position, its ubiquitous landscapes of intermingled boreal forests and lakes, and its low population density. Finland can be divided into three areas: archipelagoes and coastal lowlands, a slightly higher central lake plateau and uplands to north and northeast. Bordering the Baltic Sea, Gulf of Bothnia, and Gulf of Finland, as well as Sweden to the west, Norway to the north, and Russia to the east, Finland is the northernmost country in the European Union. Most of the population and agricultural resources are concentrated in the south. Northern and eastern Finland are sparsely populated containing vast wilderness areas. Taiga forest is the dominant vegetation type.

<span class="mw-page-title-main">Geography of Sweden</span>

Sweden is a country in Northern Europe on the Scandinavian Peninsula. It borders Norway to the west ; Finland to the northeast; and the Baltic Sea and Gulf of Bothnia to the south and east. At 450,295 km2 (173,860 sq mi), Sweden is the largest country in Northern Europe, the fifth largest in Europe, and the 55th largest country in the world.

<span class="mw-page-title-main">Subarctic climate</span> Climate characterised by long, usually very cold winters, and short, cool summers

The subarctic climate is a continental climate with long, cold winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50°N to 70°N, poleward of the humid continental climates. Like other Class D climates, they are rare in the Southern Hemisphere, only found at some isolated highland elevations. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification Dfc, Dwc, Dsc, Dfd, Dwd and Dsd.

<span class="mw-page-title-main">Bothnian Bay</span> Bay in the northern Bothnian Sea

The Bothnian Bay or Bay of Bothnia is the northernmost part of the Gulf of Bothnia, which is in turn the northern part of the Baltic Sea. The land holding the bay is still rising after the weight of ice-age glaciers has been removed, and within 2,000 years the bay will be a large freshwater lake since its link to the south Kvarken is mostly less than 20 metres (66 ft) deep. The bay today is fed by several large rivers, and is relatively unaffected by tides, so has low salinity. It freezes over each year for up to six months. Compared to other parts of the Baltic, it has little plant or animal life.

<span class="mw-page-title-main">Climate of Sydney</span>

The climate of Sydney, Australia is humid subtropical, shifting from mild and cool in winter to warm and occasionally hot in the summer, with no extreme seasonal differences since the weather has some maritime influence. Though more contrasting temperatures are recorded in the inland western suburbs, as Sydney CBD is more affected by the oceanic climate drivers than the hinterland.

<span class="mw-page-title-main">Climate of Iceland</span>

Iceland has a subpolar oceanic climate near the southern coastal area and tundra inland in the highlands. The island lies in the path of the North Atlantic Current, which makes its climate more temperate than would be expected for its latitude just south of the Arctic Circle. This effect is aided by the Irminger Current, which also helps to moderate the island's temperature. The weather in Iceland is notoriously variable.

<span class="mw-page-title-main">Climate of Albania</span>

Albania has a variety of climate systems. With its coastline facing the Adriatic and Ionian seas in the Mediterranean sea, its highlands backed upon the elevated Balkan landmass, and the entire country lying at a latitude subject to a variety of weather patterns during the winter and summer seasons, however it has a high number of climatic regions for such a small area. The coastal lowlands have typically mediterranean climate while the highlands have a continental climate. In both the lowlands and the interior, the weather varies markedly from north to south.

<span class="mw-page-title-main">Climate of Norway</span>

The climate of Norway is more temperate than could be expected for such high latitudes. This is mainly due to the North Atlantic Current with its extension, the Norwegian Current, raising the air temperature; the prevailing southwesterlies bringing mild air onshore; and the general southwest–northeast orientation of the coast, which allows the westerlies to penetrate into the Arctic. The January average in Brønnøysund is 15.8C (28.6F) higher than the January average in Nome, Alaska, even though both towns are situated on the west coast of the continents at 65°N. In July the difference is reduced to 3.2C (5.8F). The January average of Yakutsk, in Siberia but slightly further south, is 42.3C (76.1F) lower than in Brønnøysund.

<span class="mw-page-title-main">Climate of Sweden</span>

The south of Sweden has a temperate climate, despite its northern latitude, with largely four distinct seasons and mild temperatures throughout the year. The winter in the far south is usually weak and is manifested only through some shorter periods with snow and sub-zero temperatures, autumn may well turn into spring there, without a distinct period of winter. The northern parts of the country have a subarctic climate while the central parts have a humid continental climate. The coastal south can be defined as having either a humid continental climate using the 0 °C isotherm, or an oceanic climate using the –3 °C isotherm.
