## History

The history of Jokioinen is tightly connected to the Jokioinen estate, which was established in 1562. The estate developed into the largest estate in Finland during the time of the provincial governor Ernst Gustaf von Willebrand. At the beginning of 20th century the estate had a corn mill, saw mill, a brick factory, steel plant and a sugar and syrup factory.
Due to the crofters law of 1918 and the land reform law of 1945 the estate was split into more than 1500 homes and small farms. The rest of the estate was transferred to the ownership of the Finnish state in 1918. In 1928 the Department of Finnish Plant Breeding from Tikkurila and in 1957 the observatory from Pasila were transferred to the Jokioinen estate.

## Climate

Jokioinen has a humid continental climate of the warm-summer type (Köppen: Dfb), typical of the South Finnish fringe. In the past it falls to the continental subarctic zone (Dfc, based in old data) with only 3 months above 10 °C. The conditions are similar to Tampere, although it is more than 70 km to the north which shows influence of the urbanization in the climate.
