2011–12 South-West Indian Ocean cyclone season

The 2011–12 South-West Indian Ocean cyclone season was a slightly above average event in tropical cyclone formation. It began on November 15, 2011, and ended on April 30, 2012, with the exception for Mauritius and the Seychelles, for which it ended on May 15, 2012. These dates conventionally delimit the period of each year when most tropical cyclones form in the region; however, Severe Tropical Storm Kuena developed in early June, after the season had officially ended. 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.
