Located in the southwest of Finland, Southern Ostrobothnia is bordered to the west by the region of Ostrobothnia itself and with Central Ostrobothnia to the north. Consisting of 17 different municipalities, and 8 of them holding the status of being a city, Southern Ostrobothnia is a region of diverse landscapes, fascinating culture and a sub-arctic climate.


Population and Climate


Southern Ostrobothnia has a subarctic climate, which is characterized by short, mild summers and long, freezing winters with plenty of snowfall. Temperatures here can range anywhere as low as -13 °C in the winter to as high as 18 °C in the summer month of July.


As for the population, Southern Ostrobothnia is home to almost 200,000 people with most of the locals living within the major cities and near the impressive Lake Lappajärvi.


Landscapes and Lakes


One of the most unique natural wonders of Southern Ostrobothnia, Lake Lappajärvi is named after the municipality of Lappajärvi. There are many lakes in Finland of course, but what makes this one stand out from the others is that it was formed thanks to a meteor crater and there are only a few of them found throughout the country. Dating back to a prehistoric past, the impact that led to the Lappajärvi Lake forming is said to be over 75 million years old in the Late Cretaceous period. It is the subject of constant study and research and is helpful in identifying what the area around Finland might have looked like millions of years ago.


Kärnä Island is a single island located in the middle of the lake and it gets its name from the type of black rock that was formed from the original impact. Two towns, Lappajärvi and Vimpeli, are also located on the shore of Lake Lappajärvi.
