Mean annual temperature

Spatial maps of air temperature and related quantities were calculated from gridded Australian Water Availability Project (AWAP) data. Mean annual temperatures at selected weather stations were calculated from Australian Bureau of Meteorology Australian Climate Observations Reference Network – Surface Air Temperature (ACORN–SAT) datasets.

All datasets were current as at February 2020. Subsequent updates to data may result in minor changes to some values. The ACORN–SAT datasets contained data up to May 2019 at most locations.

For each location, mean annual temperatures (where available) are plotted for the extent of the ACORN–SAT dataset records. Rolling 10-year averages are plotted only if there are 10 consecutive years of annual data. The Bureau of Meteorology currently calculate temperature anomalies based on the 1961 to 1990 period.
