The 2004–05 South-West Indian Ocean cyclone season was a slightly above average event in tropical cyclone formation. It started on November 15, 2004 and ended on April 30, 2005. For Mauritius and the Seychelles, the season continued until May 15. These dates conventionally delimit the period of each year when most tropical cyclones form in the basin, which is west of 90°E and south of the Equator. Tropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion.
On August 30, an area of low pressure developed near the edge of Météo-France's area of responsibility within an unseasonably active monsoonal band which coincided with the Madden–Julian oscillation. Tracking towards the southeast, the low experience strong deep-level wind shear which kept most of the convection displaced from the center of circulation. On August 31, convection managed to develop around the west and southwestern portions of the low before and was designated as Tropical Depression 01. The depression reached its peak intensity at this time with winds of 55 km/h (35 mph 10-minute winds) and a minimum pressure of 999 hPa (mbar). Shortly after, the depression entered Australian Bureau of Meteorology in Perth's area of responsibility. The depression later intensified into a tropical cyclone and was named Phoebe.
