Geography edit
Tjörn is connected in the east to the town of Stenungsund on the mainland by the Tjörn Bridge, and to the island of Orust in the north by the Skåpesund bridge.
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 edit
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.
