Lulea, where it's located

The climate of Lulea is cold continental, with freezing winters and mild summers.
The city is located in northern Sweden, in the province of Norrbotten, in the northernmost part of the Gulf of Bothnia (called Bottenviken), which in winter can freeze. Since we are at the 65th parallel, therefore south of the Arctic Circle, you cannot see the midnight sun, however, it's enough to go 30 km (18 mi) to the north, in Boden, to see the midnight sun from June 17th to June 26th. The white nights, when the sun sets but it is not completely dark even at midnight, occur for a long period, from April 24 to August 20. In December, at noon, the sun is just above the horizon.
