Tropical Cyclone Outlook for 2022-23

14 Oct 2022 / Australia

An above-average number of tropical cyclones is likely for Australia for the 2022–23 tropical cyclone season (November–April).

The outlook indicates that an above-average number of tropical cyclones is likely in all but the Northern region.

The Australian region has a 73% chance of having more tropical cyclones than average. Typically, 11 tropical cyclones form or pass through the Australian region in a season, with around four of these crossing the Australian coast. Outlook accuracy for the Australian region is high.

The Western region has a 69% chance of having more tropical cyclones than average. Typically, at least 1 tropical cyclone in the Western region will create coastal impacts, regardless of how many make landfall. The average number of tropical cyclones to form in or pass through the Western region is 7 each season. Outlook accuracy for the Western region is moderate.

The Northwestern sub-region has a 70% chance of more tropical cyclones than average. Typically, 5 cyclones form in or pass through this area each season. Around 3 tropical systems (tropical cyclones, or their associated tropical lows) are expected to affect coastal areas of the Northwestern sub-region. Outlook accuracy for this region is moderate.

The Northern region has a 61% chance of more tropical cyclones than average. Typically, the Northern region experiences 2 or 3 cyclones each season. About three-quarters of the tropical cyclones in the Northern region have some form of impact upon coastal regions. Outlook accuracy for this region is low.

The Eastern region has a 74% chance of more tropical cyclones than average. The average number of tropical cyclones for this region is 4, and around one of these make landfall. Outlook accuracy for this region is moderate.

The tropical cyclone season typically runs from 1 November to 30 April, although tropical cyclones can and do form outside of those bounds. The broader Australian region covers the area south of the Equator and between 90°E and 160°E, and includes Australian, Papua New Guinea, and Indonesian areas of responsibility.
