2024–25 Australian region cyclone season

The 2024–25 Australian region cyclone season was an above-average and damaging tropical cyclone season, producing 12 tropical cyclones and 8 severe tropical cyclones. Notably, it was the first above-average season in almost two decades, with the highest number of both tropical cyclones and severe tropical cyclones since the 2005–06 season. It was also the third consecutive season with at least five severe tropical cyclones. The season officially began on 1 November 2024 and ended on 30 April 2025. However, tropical cyclone formation is possible at any time, with any system forming between 1 July 2024 and 30 June 2025 counted as part of the season, as evidenced by Tropical Low 33U which developed in early May.

The first storm of the season, Robyn, was first noted by the Bureau of Meteorology (BOM) on 23 November 2024, eventually intensifying into a tropical cyclone 5 days later and peaking as a category 2. The precursor to Robyn caused heavy rainfall that killed 41 people in Indonesia. Multiple tropical lows developed during December, including 07U, which was classified as a tropical storm by the Joint Typhoon Warning Center (JTWC). The second tropical cyclone of the season, 09U, developed on 8 January. Operationally considered a tropical low, it was upgraded to a tropical cyclone in post-analysis. Later in January, Cyclone Sean formed and peaked as a category 4, becoming the first of eight severe tropical cyclones. 5 tropical cyclones formed in February, with all intensifying into severe tropical cyclones. Cyclone Zelia became the first category 5 of the season on 13 February before striking the coast of Western Australia the next day. Alfred meandered off the coast of Queensland for over 2 weeks before eventually making landfall in South East Queensland on 7 March.

March produced 3 tropical cyclones. 25U formed on 17 March, and was the second cyclone of the season to be operationally unnamed. Courtney was first noted on 22 March and intensified into the second category 5 cyclone of the season a week later before crossing into the South-West Indian Ocean. Dianne formed on 26 March, strengthening into a category 2 and making landfall in the Kimberley region of Western Australia. The final tropical cyclone of the season, Errol, developed on 9 April. It remained weak for almost a week before rapidly intensifying into a category 5 on 15-16 April. Errol soon weakened and made landfall in Western Australia before dissipating on 18 April. Two tropical lows, 30U and 33U, formed in the Arafura Sea in mid-April and early May, respectively. Both systems were classified as tropical storms by the JTWC. The season officially concluded on 12 May with the dissipation of 33U. Collectively, the cyclones during the season caused over $2 billion (2024 USD) in damage, mostly due to Zelia and Alfred, and 54 deaths, mostly due to Robyn.
