2023–24 South-West Indian Ocean cyclone season

The 2023–24 South-West Indian Ocean tropical cyclone season was a near-average South-West Indian Ocean tropical cyclone season. The majority of the tropical cyclones forming within this basin are monitored by the Regional Specialized Meteorological Center (RSMC) headquartered in Réunion, an overseas department of France.

The season's first storm, Moderate Tropical Storm Amelie, developed on November 29. Several days later, Moderate Tropical Storm Bora developed, as well as Moderate Tropical Storm Clove a further two weeks later. Throughout January 2024, two more tropical cyclones, Severe Tropical Storms Dacara and Elsa, formed. Next, two storms, Tropical Cyclone Fanta and Moderate Tropical Storm Glimmer, formed in February, followed by an additional two storms, Severe Tropical Storm Hazelle and Moderate Tropical Storm Ilene, developing in March. Finally, in April, Tropical Cyclone Jile formed, becoming the season's strongest cyclone. Although a number of storms, five, became severe tropical storms, only two, Fanta and Jile, intensified further into tropical cyclones.

Four tropical cyclones (Amelie, Bora, Elsa, and Jile) affected land during the 2023–24 South-Western Indian Ocean cyclone season, two (Amelie and Bora) of which made landfall, both over Madagascar. Amelie, Bora, and Jile all tapped Madagascar with slight precipitation; on the contrary, mass flooding in Réunion was reported from Elsa. Collectively, the storms of the 2023–24 South-West Indian Ocean cyclone season caused nine fatalities and $900,000 (2024 USD) in losses.

Season summary
For the entirety of the 2023–24 South-West Indian Ocean cyclone season, the Météo-France's (MFR) meteorological department in Réunion issued advisories on all tropical cyclones that formed in the Indian Ocean south of the Equator and between 90º E and the coastline of the African mainland. To assess a cyclone's intensity, the MFR used the Dvorak technique. Also, the Joint Typhoon Warning Center (JTWC), a joint United States Navy – United States Air Force task force, issued advisories for all of the season's tropical cyclones alongside the MFR. Overall, both agencies tracked ten named storms, slightly above the long-term average of nine.
