According to the Bureau of Meteorology, 2018 was the fourth warmest year since global records began in 1880. 

The global mean surface temperature was 0.66°C above 1961–1990 average figures. And, while the Earth itself has warmed 1.1°C since pre-industrial temperatures, climate variables such as the 2015-16 El Niño warming event meant that 2018 came in well behind 2016’s record of 0.85°C above "average", as well as 2017 at 0.75°C and 2015 at 0.74°C.
