Adelaide, Jan 24 : Adelaide has hit a sweltering 46.6 degrees Celsius, surpassing the previous record set in Melbourne a decade ago to officially become the hottest capital in the country, said an ABC News report.
Earlier on Thursday, Adelaide topped its 1939 heat record after hitting 46.2C. The temperature then climbed up to 46.6C, topping the previous capital city record of 46.4C set in Melbourne in 2009.
So far, 22 locations have hit record temperatures including Adelaide Airport, Minlaton, Noarlunga, Snowtown and Port Lincoln. Ceduna set a record for the second day in a row reaching 48.6C.
The Bureau of Meteorology (BOM) is tipping more records will be surpassed this afternoon. Meteorologist Hilary Wilson said records were breaking across the state.
"It really is quite something to see this many records broken in one day," Ms Wilson said.
"It's preliminary at this stage but when we do the figures it wouldn't be at all surprising to see that this was the hottest day ever for South Australia as a whole.
"Typically the hottest time of the day is mid-afternoon so Adelaide could still sneak up a little bit higher."
Earlier in the day, the BOM said up to 23 locations in South Australia could break record high temperatures today, including Mount Barker, Clare and Maitland.
The Yorke Peninsula town of Minlaton was the first town to beat its previous record of 45.6C. A temperature of 45.7C was measured by the BOM at 11:14am.
Adelaide's previous maximum temperature of 46.1C was set in 1939, just above the original 45C Thursday forecast. (UNI)
