“The year started off very warm and dry, with bushfires in Victoria, Tasmania and Western Australia, and a nation-wide heatwave from late February to mid-March. We had our warmest autumn on record partly due to a very strong 2015–16 El Niño," Mr Plummer said.
“In May the El Niño broke down and the dry start was followed by record wet from May to September as a negative Indian Ocean Dipole developed, with ocean waters warming to the northwest of Australia.
“Widespread, drought-breaking rains led to flooding in multiple states. Even northern Australia saw widespread rainfall, during what is usually the dry season, greening regions that had been in drought for several years,” he said.
Notable events during the wet period included an East Coast Low in June, causing flooding down the east coast of Australia to Tasmania, and damaging coastal erosion in New South Wales. There were also significant storm and wind events which affected the southeast.
