Seasonal Heat Load Outlook

March to May (2018)

  • Warmer than average days and nights are expected in the northeast, central and southern parts of Australia.
  • Eastern NSW, southeast QLD, and northwest Australia have roughly equal chances of a warmer or cooler than average three months.


  • A declining La Nina is present in the Pacific Ocean, with models suggesting the event will end by early autumn.
  • The autumn rainfall outlook shows large parts of central Australia are likely to have a drier than average autumn, including the southern NT, western QLD, northwest VIC and scattered parts of eastern SA and WA. However, Tasmania may have a wetter than average autumn.
This information is based on the seasonal outlook provided by the Australian Bureau of Meteorology.

Given the warmer than average conditions in northern QLD, southern VIC, and TAS, the heat load conditions are expected to be higher than normal; however, the possible reduction in rainfall may offset the increased temperature resulting in near normal heat load over the next three months in these regions.
