The 2000–01 South-West Indian Ocean cyclone season was a fairly quiet season with only five named storms, although there was an additional unnamed tropical storm and two subtropical cyclones with gale-force winds. It started early, with a tropical disturbance forming on August 1 – the first day of the cyclone year. However, the first named storm, Ando, was not named until January 2, which at the time was the 4th latest on record. Ando would become the most intense cyclone of the year, reaching peak winds of 195 km/h (121 mph) according to the Météo-France office (MFR) on Réunion, the official Regional Specialized Meteorological Center for the basin. The agency tracked storms south of the equator and west of 90°E to the east coast of Africa.

A subtropical cyclone is a weather system that has some characteristics of both tropical and extratropical cyclones.
