On the first day of spring it was shivering cold in Sydney, with the city experiencing its coldest September morning in 17 years. A stunningly bright full moon in clear skies brought a very cold morning to the New South Wales capital. The city woke to a chilling 5.5 degrees, more than 5 degrees below average for September. This makes it the coldest morning of the year, and the coldest start to spring in 45 years. Western suburbs were even colder with Bankstown reaching 4 degrees, Penrith 2 degrees, Richmond -1 degrees and Camden a freezing -2 degrees. Winds along the coast were fresh and those who went for a sunrise jog would have felt the brisk winds, making it feel even colder. A large high pressure system clearing skies in the wake of a front has been responsible for the chilly morning. This front has left behind a cold pool of air, which brought snow down to places such as Canberra and Goulburn yesterday evening. Both Canberra Airport and Goulburn also experienced their coldest September nights on records, plummetting to -6.8 degrees and -7.4 degrees respectively. Clear skies will bring plenty of sunshine today and slightly warming temperatures ideal for outdoor activities. With the stronger sun the UV index has increased to moderate, calling hats and sunscreens.
