Australia experienced in 2014 its highest springtime mean maximum temperature (Tmax) since records began in 1910. The Australian-mean Tmax was 2.32°C above the 1961–90 mean, and 0.26°C warmer than the previous record set in 2013 (Bureau of Meteorology 2014). While September was very warm, both October and November had the hottest Australia-average Tmax on record, with maximum temperatures 2.76°C and 2.18°C above their 1961–90 means, respectively, and the south-east was particularly warm. Here we focus on the causes of the October–November extreme Tmax anomaly.
