“A wintry weather pattern has dropped temperatures up to ten degrees below average across south-eastern Australia, bringing cool relief for South Australia and Victoria. Sadly for Sydney the cool temperatures are just another reminder of the ongoing summer fizzer,” says Tom Saunders, Senior Meteorologist at The Weather Channel.

“During the weekend hot northerly winds lifted temperatures above 30˚C in Adelaide and Melbourne before a cold-front swept across south-eastern Australia, bringing strong winds and a dramatic cool change. Melbourne was roasting at 30˚C at 3pm Sunday but fell 14˚C in less than two hours as gusty, northerly winds above 90 km/h shifted to a cold south-westerly,” he continues.

“The change dropped Adelaide’s maximum 10˚C from Saturday to Sunday and brought 16mm of rain, more than the city normally receives throughout the whole month,” says Saunders.

“In Sydney it’s fair to say that summer is now almost a complete write off. The gusty change reached Sydney early this morning, setting the city up for another week of onshore winds, cloud and showers,” Saunders continues.

“Sydney is on track for its coldest summer since 1965 with an average temperature so far at just over 21˚C. Sydney’s maximum temperatures this summer have averaged 24.5˚C, over one degree below average and putting us on track to be the lowest since 1953.” “Temperatures across south-eastern Australia will remain well below average this week as cool southerly winds persist,” he concludes.
