The 2025–26 South-West Indian Ocean cyclone season is the current annual cycle of tropical cyclone and subtropical cyclone formation in the South-West Indian Ocean. It officially began on 15 November 2025, and will end on 30 April 2026, with the exception for Mauritius and the Seychelles, for which it will end on 15 May 2026. 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 2025 and 30 June 2026, such as 01, Awo, Blossom and Chenge, also part of the season. Tropical and subtropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion and unofficially by the Joint Typhoon Warning Center.
