The 1992–93 South-West Indian Ocean cyclone season lasted longer than normal, with the first storm Aviona forming on September 27 and the final storm Konita not dissipating until May 7. It was an above-average season, with four tropical cyclones – the equivalent of a minimal hurricane – along with six tropical storms, one subtropical depression, and several depressions including one that was named. The basin is defined as the area west of 90°E and south of the Equator in the Indian Ocean, which includes the waters around Madagascar westward to the east coast of Africa. Tropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion (MFR), as well as by the Joint Typhoon Warning Center (JTWC).
At the time, the season officially went from November 15, 1991, to April 30, 1992, although this season began in September with the formation of Tropical Storm Aviona in the northeastern portion of the basin. A month later, Tropical Storm Babie also formed in the northeastern portion of the basin before the season's official start. After several depressions formed in December and early January, Cyclone Colina formed and struck Réunion, which damaged houses and killed 2 people and left 12 missing there. Three storms were active at the same time in the middle of January, including Colina – Tropical Storm Dessilia moved across Madagascar with gusty winds, and Cyclone Edwina was the longest-lasting and strongest storm of the season. Edwina brushed the Mascarene Islands with gusty winds and light rainfall. In mid-February, Tropical Storm Finella brought locally heavy rainfall to Réunion, reaching 1,074 mm (42.3 in) along the island's east coast and causing minimal rainfall along the southern coast. The Intertropical Convergence Zone (ITCZ) became active toward the end of February, spawning tropical storms Gracia and Ionia as well as Tropical Depression Hutelle. Ionia, the last of five system to cross Madagascar during the season, killed eight people in the country. The season ended with Cyclone Jourdanne, which was the second-strongest storm of the season in April, and Cyclone Konita in May.
