Quick Summary

Meteorologists predict record early September temperatures for Sydney and Brisbane, with maximum temperatures expected to reach up to 33C in Sydney's suburbs, smashing average September records by up to 13C. The heat is due to an intense north-westerly airstream blowing from the northern interior, which will lift temperatures significantly. This is part of a broader pattern of unseasonably warm weather across eastern Australia, with snow forecast in southern NSW. According to meteorologist Tom Saunders, Sydney's first five days of September are on track to average a top temperature of 27C, matching its midsummer average.

Story summary

A total fire ban was issued for Sydney on Saturday due to extremely hot and dry conditions, with the city expected to reach 33 degrees. The Bureau of Meteorology's Robert Urbaniak warned that the "very dry, very windy" conditions combined with low humidity would increase the risk of fires. Mean winds of up to 50km/h and wind gusts of up to 70km/h were forecasted, along with a relative humidity of just 20%. The temperatures were above average for this time of year, with 32 degrees in Penrith and 33 degrees in Sydney, 10 degrees warmer than the usual maximum temperature in September. The extreme fire danger was not limited to Sydney, but also affected the region stretching from the coast to Mount Victoria. A few days earlier, Sydney had experienced its warmest winter on record in 167 years, which made these conditions even more concerning. The heatwave was expected to break records, with temperatures potentially reaching as high as 13 degrees above average in some areas.

Narrative

The Bureau of Meteorology had forecast snowfall to hit Thredbo top station by 4pm on Saturday, with a daytime low temperature of -1C. The new falls won’t do much to help the parlous cover remaining on Australia’s ski fields after a warm winter, however. The Weatherzone journalist Anthony Sharwood on Friday wrote: “September snowfalls are meaningful when there’s a decent remnant snowpack from winter onto which the new snow can bond.
