The majority of South Australia experienced well above average minimum and maximum temperatures throughout September, contributing to the nation's heat records. Adelaide's 2013 September average was 22.3 degrees, 3.3 degrees above the long term average and its hottest September in at least 36 years. Marree in the states north averaged 31.9 degrees, 6.2 degrees above its September average and it's hottest since records began in 1939. While along the West Coast in Ceduna 26.5 degrees was the norm, 5.1 degrees above the September average and it’s warmest in 71 years. SA's overnight temperatures throughout September didn't bring too much relief either. Robe's September average minimum temperature was 11.2 degrees, the warmest in 125 years of records. Rosedale in the states south averaged an overnight temperature of 9.3 degrees, the warmest it's been in over half a century. A lack of strong cold fronts and a significant build-up of heat over inland Australia caused these temperatures to soar into the record books.
