Over 100 different weather recording stations reported their hottest September day or night in at least a decade over the weekend.
Wilcannia in NSW’s northwest now holds the state record for the highest September maximum temperature at 40.5 degrees, recorded on Saturday, according to Weatherzone.
Mildura also beat Victoria’s September record at 37.7 degrees.
The sweltering temperatures also persisted overnight over NSW and southern Queensland. Sydney saw its hottest September minimum in 158 years of records only falling to 23.0 degrees at 9am on Saturday. Despite this, temperatures were around 27-29 degrees through much of the night.
Half of all observation stations (61 out of around 120) in NSW, in conjunction with 28 stations in VIC and three stations in Queensland, recorded their hottest September day or night in at least the last decade. In NSW and QLD, 18 stations sweated through their hottest September night on record.
The complex low pressure system and trough is continuing to bring hot and windy conditions to northern NSW and southern Queensland today and for the next few days. A substantial cool change for these areas is not expected until next Saturday, with a strong cold front.
