Rauðilækur (in Icelandic pronounced as /ˈrœyːðɪˌlaiːkʏr̥/, or Syðri-Rauðalækur in Icelandic pronounced as /ˈsɪðrɪ-ˌrœyːðaˌlaiːkʏr̥/) is a small village, more a hamlet, just beside the small town of Hella in southern Iceland.[1] Established in 1902, the village is named after the stream of the same name that flows on the east side of the hamlet. In 2011 it had a population of 43.
The hamlet and the river are located about 90km (60miles) southeast of Reykjavík, in the southern region and coastline area, which is characterized by peninsulas, coves, straits, and islands. Temperatures very rarely drop below -15C during the winter. This is because the Icelandic coastal weather in winter is moderated by the warm waters of the Gulf Stream. The climate is subpolar oceanic (Koppen: Cfc). Its coastal location, it is about 20km (10miles) far from the North Atlantic Ocean, does make it prone to wind, and gales are common in winter. Summers are cool, with temperatures fluctuating between 10C15C, sometimes exceeding 20C.
