The 2021–22 South-West Indian Ocean cyclone season is a ongoing event of the annual cycle of tropical cyclone and subtropical cyclone formation. It began on 15 November 2021, and it will end on 30 April 2022, with the exception for Mauritius and the Seychelles, for which it will end on 15 May 2022. 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 that form at any time between 1 July 2021 and 30 June 2022 will count towards the season total. Tropical and subtropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion.

Storm names[]

Within the South-West Indian Ocean, tropical depressions and subtropical depressions that are judged to have 10-minute sustained windspeeds of 65 km/h (40 mph) by the Regional Specialized Meteorological Center on La Réunion Island, France (RSMC La Réunion) are usually assigned a name. However, it is the Sub-Regional Tropical Cyclone Advisory Centers in Mauritius and Madagascar who name the systems. The Sub-Regional Tropical Cyclone Advisory Center in Mauritius names a storm should it intensify into a moderate tropical storm between 55°E and 90°E. If instead a cyclone intensifies into a moderate tropical storm between 30°E and 55°E then the Sub-Regional Tropical Cyclone Advisory Center in Madagascar assigns the appropriate name to the storm. Beginning from the 2016–17 season, name lists within the South-West Indian Ocean will be rotated on a triennial basis. Storm names are only used once, so any storm name used this year will be removed from rotation and replaced with a new name for the 2024–25 season. The unused names are expected to be reused in the list for the 2024–25 season.[1] All of the names are the same with the exception of Ana, Batsirai, Cliff, Damako, Emnati, Fezile, Gomba, Halima, Issa, Jasmine, Karim, and Letlama which replaced Alcide, Bouchra, Cilida, Desmond, Eketsang, Funani, Gelena, Haleh, Idai, Joaninha, Kenneth, and Lorna from the 2018–19 season.

Season effects[]

This table lists all of the tropical cyclones and subtropical cyclones that were monitored during the 2021–2022 South-West Indian Ocean cyclone season. Information on their intensity, duration, name, areas affected, primarily comes from RSMC La Réunion. Death and damage reports come from either press reports or the relevant national disaster management agency while the damage totals are given in 2021 or 2022 USD.
