Australia has marked the start of the first week of winter with record lows and incredible snowfalls. This morning has continued the trend with Sydney registering its coldest winter start since 1989. Mercury dropped to a low of 7ºC.
With a week of low season and three more months on the rise, let’s take a look at what winter awaits us.

These above-average rains will aggravate the risk of sudden flooding in the southeast, as ground catchments are saturated.
Below-average falls will be felt in southwestern Australia and western Tasmania, the office added.
The rain is driven by the meteorological phenomenon of La Niña, which “will gradually weaken” over the coming months.
The Office of Meteorology model predicts the possibility of above-average rainfall in July 2022. (BoM) “Compared to two weeks ago, the temperatures of the surface of the tropical Pacific Sea have warmed, especially in the western half of the tropical pacific, returning to average values, “BoM said.
“However, some weather indicators continue to show a sign of La Niña.”
This end of the rain, and the Girl, are also hampered by the “likely” formation of a negative Indian Ocean dipole (IOD).

“A negative IOD increases the chances of winter and spring rains above average in much of Australia,” BoM said.
“It also increases the chances of warmer days and nights in North Australia.”
The Indian Ocean dipole (IOD) is currently neutral.
Although the southeast has experienced extreme cold this week, the BoM predicts warmer-than-average minimum temperatures for much of Australia, as well as warmer-than-average nights.
There are exceptions to this; Colder-than-average days are expected for central and inland areas.
