In eastern Australia, persistent rain saw significant flooding affecting large areas multiple times during the year. Rainfall was below average for western Tasmania, much of the central and eastern Top End in the Northern Territory, and for the far south-west of Western Australia. Rainfall for the year was above average for most of mainland Australia, and very much above average for the south-eastern quarter of the mainland. The national rainfall dataset commences in 1900. Rainfall for Australia was 26% above average for the nation as a whole at 587.8 mm (compared to the 1961–1990 average of 466.0 mm). Nationally, 2022 was Australia's ninth-wettest year on record. Conversely, the annual mean temperature was below average for a large area of central to northern New South Wales inland of the coastal ranges. The national temperature dataset, ACORN-SAT, commences in 1910 and spans 113 years of observations.Ģ022 was Australia's equal-22nd-warmest year on record, compared to all years since 1910, and the coolest year since 2012.Īnnual mean temperatures for 2022 were above average for northern Australia Tasmania, most of Victoria, and south-east South Australia and large parts of the west and north of Western Australia. The mean maximum temperature was 0.32 ☌ above average and the mean minimum temperature was 0.67 ☌ above average. About deciles.Īustralia's area-averaged mean temperature for 2022 was 0.50 ☌ above the 1961–1990 average. The main climate influences active during 2022 were La Niña, which persisted through summer 2021–22, dissipated during autumn, then re-developed in early September and continued through the end of 2022 a negative Indian Ocean Dipole in winter and spring and a persistently positive phase of the Southern Annular Mode from mid-autumn onwards.Ĭonfluence of climate drivers brings exceptionally wet year for the mainland south-eastĢ022 annual rainfall compared to historical rainfall observations. Water storage levels have been high across much of Australia during 2022, although some storages remained at low levels in parts of central coast Queensland, western Tasmania, south-east New South Wales, and western Victoria. Rainfall was very much above average for the south-eastern quarter of the mainland, compared to all years since 1900, but below average for western Tasmania, much of the north of the Northern Territory, and the far south-west of Western Australia. Nationally-averaged rainfall was 26% above the 1961–1990 average at 587.8 mm, which makes 2022 the ninth-wettest year on record for Australia. It was especially warm for the tropics, with severe to extreme heatwave conditions affecting parts of the north and the west several times during 2022. The mean annual minimum temperature was above or very much above average for the majority of Australia. The mean annual maximum temperature was above average for most of northern Australia, Tasmania, and parts of the west coast, but below average for New South Wales, southern Queensland, and parts of South Australia. Wetter and warmer than average for Australia overallĪustralia's national mean temperature was 0.50 ☌ warmer than the 1961–1990 average, making 2022 the equal-22nd-warmest year on record.
