The 2024–25 South-West Indian Ocean cyclone season was tied as the third-busiest season in the South-West Indian Ocean since records began in 1967, and the costliest in the basin, surpassing the 2018–19 season, mostly due to Cyclone Chido. It was an above-average season featuring thirteen named storms, nine tropical cyclones, six intense tropical cyclones, and only one very intense tropical cyclone. The season began on 15 November 2024 and ended on 30 April 2025, with the exception of Mauritius and the Seychelles, for which it ended on 15 May 2025. These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of 90°E and south of the Equator. However, tropical cyclones can form year-round, with any cyclone forming between 1 July 2024 and 30 June 2025, such as 01, Ancha, and Bheki, being part of the season.
