Tjörn (Swedish pronunciation:[ˈɕœːɳ]) is the sixth largest island in Sweden,[1] located on the Swedish west coast in the province of Bohuslän.
The area of the island is 147 square kilometres (57 sq mi), and the area of the municipality is 168 square kilometres (65 sq mi). The population, as of 2017, was 15,774 people.[2]
The largest town is Skärhamn, and it is also the municipal capital. Other communities, many of which are fishing communities, include Rönnäng, Klädesholmen, and Kyrkesund. The peninsula of Mjörn has large shell banks.
Climate
Tjörn has a maritime climate influenced by its location off the coastline. Even so, the proximity to the mainland means that the weather station of Rörastrand more resembles a mainland coastal climate than one of the archipelago.
