The 2022 Australian winter was an average year for Australian winter, having an average temperature of 0.36°C above the 1961–1990 average, yet still the coldest winter since 2014. The winter season began with the June winter solstice on June 21, and concluded on September 23 with the September equinox. The meteorological winter officially began on June 1 and concluded on August 31.

Seasonal forecasts
The winter of 2022 in Australia was forecasted to be cold and wet, with predictions indicating an elevated snowfall, frequent flooding, as well as dangerous east coast lows. The lead-up to winter had been particularly wet, characterized by above-average rainfall from January to May, leaving much of the country with saturated soils and bulging rivers and dams. Meteorologists anticipated that the persistent La Niña pattern in the Pacific Ocean, coupled with the development of a negative Indian Ocean Dipole (IOD), would drive increased rainfall and lower daytime temperatures across large areas of Australia. This combination was expected to significantly raise the likelihood of an unusually wet and cloudy winter, heightening the risk of flooding, particularly in regions that experienced a wet summer and autumn.

Temperature forecasts predicted that increased cloud cover would keep daytime temperatures below average in central, eastern, and parts of southern Australia, while overnight temperatures were expected to be warmer than usual due to limited cooling. Frost frequency and intensity were forecasted to decrease, although periods of clear skies were still predicted to bring frosty mornings. Snowfall prospects in the Alpine regions appeared promising, contingent on the strength and frequency of cold fronts, influenced by the Southern Annular Mode (SAM). Additionally, the abnormally warm Tasman Sea was expected to fuel the formation of East Coast Lows, potentially exacerbating flooding and coastal erosion along Australia's eastern seaboard. The overarching influence of climate change, characterized by warmer winters and reduced rainfall in south-eastern and south-western Australia, continued to impact the nation's winter weather patterns.
