The weather bureau say a 16-year-old record of 14 days above 30 degrees Celsius in February has been equalled, but not broken.
The mercury had to reach 30 degrees Celsius in the city to make it the 15th day of the month to reach that temperature.
The official peak was 29.7C. Initially the weather bureau said the figure would be rounded up and recorded as 30C.
However subsequent investigations have found that in 2009, two temperatures of 29.9 were not rounded up.
So the bureau has declared the record has not been broken.
The last record of 14 days above 30C was set in 1997.
Weather bureau forecaster, Rod Dixon, says overnight temperatures have been especially high, leading to some uncomfortable nights.
"The next couple of nights, we're not going to see any respite from that,
"Minimum temperatures are still around the 20 degree mark over much of the state.
"But from Thursday onwards, we'll see a southerly change move across the state and that will flush out much of the moisture that's causing the humid conditions and warm overnight temperatures."
Mr Dixon says while the days have been consistently warm, there have not been many days of extreme temperatures.
