Heat wave events headline a record warm summer for Australia

This summer, Australia experienced a range of severe weather including floods, bushfires and ongoing drought, but it was a persistent period of significant heat during December and January that headlined the past three months.

This information comes from the Bureau of Meteorology’s recently released its national, State, and Northern Territory summaries for the recent summer period.

Bureau climatologist Dr Lynette Bettio said the heatwave events during December and January played a major role in the recent summer being Australia’s warmest on record.

“The heat we saw this summer was unprecedented. While the final numbers are yet to be analysed, we know it will be the warmest on record for Australia as a whole, and many individual locations will have broken summer heat records as well,” Bettio said.

“There was a noticeable absence of strong cold fronts that would normally bring relief during summer. A lot of this was caused by persistent high pressure systems sitting over the Tasman Sea that was blocking those fronts from impacting the south of the country, especially during January.

“Rainfall was also well below average for many places, apart from areas in northern Queensland, where we saw a significant rain event during late January to early February.”
