Australia experienced an extreme heatwave during January 2014. In early January, maximum temperatures in excess of 40C were experienced on successive days across Australia.[1][2]

Adelaide is predicted to be the hottest city in the world on Thursday 16 January 2014.[3]

Blistering heat formed over the Nullarbor at the end of December and continues over parts of inland Australia smashed temperature records and was a "highly significant" event according to the Bureau of Meteorology.

In a special climate statement released on Monday 13 January 2014, the bureau said the latest heatwave, while less extensive and prolonged than the record-breaking hot spell to start 2013, was still a remarkable event.

The report comes days after the bureau confirmed that 2013 was Australia’s hottest in more than a century of records, easily beating 2005.

A major feature of the [latest] heatwave was the very large margin by which some records were broken, particularly in northern New South Wales," the bureau said.

At Narrabri (NSW), 47.8 degrees observed on 3 January surpassed the previous record by 3.6 degrees, the largest such margin at any Australian location with 40 or more years of data.

The heatwave began on December 27 in eastern Western Australia and spread slowly north and east, setting records at 34 sites where data has been collected for at least 40 years. Most of those sites were in Queensland and northern NSW.

Parts of north-western Western Australia were hit by another bout of extreme heat with bureau charts indicating regions may reach 50 degrees on Thursday.

In Queensland the statewide mean temperature on January 3 shattering the previous record by "an extraordinary 0.75 degrees", the bureau said.

More than 10 per cent of Queensland and almost 15 per cent of NSW had their hottest day on record.

Gunnedah Research (northern NSW) broke its previous temperature record by 2.8 degrees, the largest margin between the first and second-highest readings in any of the 112 primary locations used by the bureau.

During the heatwave, Roma in southern Queensland broke its record high temperature on three separate days - December 29 and 30, and on January 3.

Melbourne experienced 4 successive days of over 40C during mid January 2014, including 44C on Thursday 16 January 2014.

Power outages were experienced during peak power usage periods during the extreme heat.[4][5]

Power generation was unable to keep up with demand during peak power usage periods and rolling brownouts (also known as "load shedding") were conducted by electricity utility companies.

Numerous power outages were also experienced due to faults. Citipower and Powercor reported 1766 outages across Victoria, including 225 in the Geelong area, 140 in Waubra, north-west of Ballarat, and 114 in St Albans.
