2023–24 South-West Indian Ocean cyclone season

In October 2023, Météo-France issued its seasonal forecast of cyclone activity for the basin, predicting a below-average season with 5–8 moderate tropical storms due to an expected strong El Niño event. The MFR also stated that the chance for a below-average season was 70%. Average cyclone activity was given a 20% chance, while an above-average level of activity was given a 10% chance.{{cite web|title=Prévision saisonnière d'activité cyclonique dans le Sud-Ouest de l'océan Indien: Saison 2023-2024|trans-title=Seasonal forecast of hurricane activity in the South West Indian Ocean Season 2023-2024|url=https://meteofrance.re/fr/actualites/prevision-saisonniere-dactivite-cyclonique-dans-le-sud-ouest-de-locean-indien-saison|publisher=Météo-France|date=26 October 2023|access-date=1 January 2024|archive-date=1 January 2024|archive-url=https://web.archive.org/web/20240101181248/https://meteofrance.re/fr/actualites/prevision-saisonniere-dactivite-cyclonique-dans-le-sud-ouest-de-locean-indien-saison|lang=fr}}

The Mauritius Meteorological Services (MMS) also released their summer outlooks for the season, stating that around six to eight cyclones were expected to form, with the region west of Diego Garcia having environmental conditions more conducive for cyclogenesis.{{cite web|title=Seasonal Outlook for Summer 2023–24|url=http://metservice.intnet.mu/climate-services/seasonal-climate-forecast.php|publisher=Mauritius Meteorological Services|date=30 October 2023|access-date=1 January 2024|archive-date=1 January 2024|archive-url=https://web.archive.org/web/20240101181929/http://metservice.intnet.mu/climate-services/seasonal-climate-forecast.php}}

The ACE index for the 2023–24 South-West Indian Ocean cyclone season as calculated by Colorado State University was 106.7 units. Through 2024, five tropical cyclones, four of which became tropical storms, formed outside the cyclone season in the southwest Indian Ocean, tying 2003 with four named storms.

The season officially started on 15 November 2023, however the first system, Alvaro, would not form until 30 December. Alvaro became a tropical depression the next day, traversing the Mozambique Channel, before making landfall in Morombe District, Madagascar on 1 January 2024. After a brief lull in activity, Tropical Cyclone Belal formed on 11 January. Belal would affect Mauritius and Reunion, killing six people.{{Cite web |date=15 January 2024 |title=One dead as storm hits French Indian Ocean island |url=https://news.yahoo.com/reunion-island-highest-alert-major-040230512.html |access-date=15 January 2024 |website=Yahoo News |lang=en-US |archive-date=1 February 2024 |archive-url=https://web.archive.org/web/20240201155819/https://news.yahoo.com/reunion-island-highest-alert-major-040230512.html |url-status=live }}{{cite news |last1=Mohabuth |first1=Yasine |last2=Vock |first2=Ido |date=15 January 2024 |title=Cyclone Belal: Flooding as storm hits Réunion and heads for Mauritius |url=https://www.bbc.com/news/world-67982380 |work=BBC |access-date=15 January 2024 |archive-date=15 January 2024 |archive-url=https://web.archive.org/web/20240115130021/https://www.bbc.com/news/world-67982380 |url-status=live }} On 22 January, Moderate Tropical Storm Candice formed.{{Cite web |date=22 January 2024 |title=CYCLONE et ACTIVITE CYCLONIQUE par Météo-France La Réunion |url=https://meteofrance.re/fr/cyclone |archive-url=https://web.archive.org/web/20240122143939/https://meteofrance.re/fr/cyclone |archive-date=22 January 2024 |access-date=22 January 2024 |website=Meteo-France}} On 25 January, Intense Tropical Cyclone Anggrek entered the basin,{{cite report |url=http://www.meteo.fr/temps/domtom/La_Reunion/webcmrs9.0/anglais/activiteope/bulletins/cmrs/CMRSA_202401251434.pdf |title=Tropical Cyclone 04 (Anggrek) Warning Number (1/4/20232024) |date=25 January 2024 |publisher=Météo-France |access-date=25 January 2024 |archive-date=25 January 2024 |archive-url=https://web.archive.org/web/20240125173732/http://www.meteo.fr/temps/domtom/La_Reunion/webcmrs9.0/anglais/activiteope/bulletins/cmrs/CMRSA_202401251434.pdf |url-status=live }} while Tropical Depression 05 emerging northeast of St. Brandon.{{cite report|title=Bulletin for Cyclonic Activity and Significant Tropical Weather in the Southwest Indian Ocean|url=http://www.meteo.fr/temps/domtom/La_Reunion/webcmrs9.0/anglais/activiteope/bulletins/zcit/ZCITA_202401251202.pdf|publisher=Météo-France|date=25 January 2024|access-date=25 January 2024|url-status=live|archive-date=16 February 2024|archive-url=https://web.archive.org/web/20240216001740/http://www.meteo.fr/temps/domtom/La_Reunion/webcmrs9.0/anglais/activiteope/bulletins/zcit/ZCITA_202401251202.pdf}} After a lull period of about 3 weeks, the strongest storm being Intense Tropical Cyclone Djoungou from 13 February and exited the basin 6 days later.{{cite JTWC|date=19 February 2024|type=warn|category=TC|designation=13S|no=9|name=Djoungou|url=https://wiki.chlod.net/jtwc/text/2024-02-19-1930-sh1324web.txt|access-date=19 February 2024}} 17 February was the day Severe Tropical Storm Eleanor brought intense rainfall and winds which left at least 2 people injured, 10,000 customers deprived of electricity, several electricity pylons damaged, and toppled trees blocking several roads.

On 25 March, a zone of disturbed weather emerged 398 nautical miles north-northeast of Toamasina, Madagascar. MFR began issuing bulletins for a potential tropical cyclone that could form in the upcoming days. A few hours later, JTWC followed suit and issued a TCFA, indicating a low-level circulation with a symmetric area of deep persistent convection obscuring the center.{{cite web|title=Tropical Cyclone Formation Alert on Tropical Disturbance (Invest 95S) |url=https://www.metoc.navy.mil/jtwc/products/sh9524web.txt|archive-url=https://web.archive.org/web/20231231130641/https://www.metoc.navy.mil/jtwc/products/sh9524web.txt|url-status=dead|archive-date=31 December 2023|work=JTWC|accessdate=March 25, 2024|date=March 25, 2024}} On the next day, JTWC designated the disturbance as Tropical Cyclone 20S. A few hours later, 20S rapidly intensified into a severe tropical storm and was assigned the name Gamane by the MMS. On 27 March, Gamane gained additional strength, further intensifying into a Category 2-equivalent tropical cyclone. Its LLCC continued to improve as it moved into more favorable conditions structurally. At 03:00 UTC, Gamane made landfall on the east coast of Madagascar, just north of Vohémar. From this point, land interaction caused Gamane to weaken significantly — in the morning of 28 March, satellite imagery demonstrated that its deep central and feeder band convection had become disorganized as it tracked inland over the mountainous terrain of Northern Madagascar.{{cite web|title=Prognostic Reasoning for Tropical Cyclone 20S (Gamane) Warning No. 5 |url=https://www.metoc.navy.mil/jtwc/products/sh2024prog.txt|archive-url=https://web.archive.org/web/20240328031115/https://www.metoc.navy.mil/jtwc/products/sh2024prog.txt|url-status=dead|archive-date=28 March 2024|work=JTWC|accessdate=March 28, 2024|date=March 28, 2024}} MFR issued its final warning after Gamane degenerated into a disturbance on March 28 at 12:00 UTC.{{cite web |language=fr |url=http://www.meteo.fr/temps/domtom/La_Reunion/webcmrs9.0/francais/activiteope/bulletins/cmrs/CMRSF_202403281249.pdf

According to a preliminary report on 28 March, Gamane generated heavy rains and floods which caused 18 deaths, one missing person, more than 2,500 displaced, and more than 600 houses flooded or damaged in the regions of Sava, Analanjirofo and Diana. The authorities reported that Sambava District received 300 mm of rain in 24 hours. Accessibility to this region is difficult in normal times and the road connecting it to the capital has been cut by the rain, which makes the arrival of aid very slow.{{cite web |language=en |url=https://reliefweb.int/report/madagascar/madagascar-tropical-cyclone-gamane-flash-update-no-1-28-march-2024 |title=Madagascar: Tropical Cyclone Gamane Flash Update No. 1, 28 March 2024 |author=United Nations Office for the Coordination of Humanitarian Affairs |date=2024-03-28 |website=reliefweb.int |access-date=2024-03-28}} On April 3, the total was raised to 19 deaths, 3 people missing and at least 90,000 affected.

On 30 April, a zone of disturbed weather was formed near Seychelles. Later, MFR started issuing initial advisories that could form in the following days. JTWC followed suit and also issued a TCFA. On 2 May, its LLCC became organized, which resulted in gaining the name Hidaya from the MMS. JTWC also followed suit and gave its identifier as Tropical Cyclone 23S. Hidaya's low-level circulation center and its deep convective banding began to wrap into the system along the southern semicircle of the system.{{cite web|title=Prognostic Reasoning for Tropical Cyclone 23S (Hidaya) Warning No. 2 |url=https://www.metoc.navy.mil/jtwc/products/sh2324prog.txt|archive-url=https://web.archive.org/web/20240502113818/https://www.metoc.navy.mil/jtwc/products/sh2324prog.txt|url-status=dead|archive-date=2 May 2024|work=JTWC|accessdate=2 May 2024|date=2 May 2024}} On 3 May, Hidaya rapidly intensified into a Category-1 cyclone after it drastically symmetrized over the past 12 hours.{{cite web|title=Prognostic Reasoning for Tropical Cyclone 23S (Hidaya) Warning No. 4 |url=https://www.metoc.navy.mil/jtwc/products/sh2324prog.txt|archive-url=https://web.archive.org/web/20240502113818/https://www.metoc.navy.mil/jtwc/products/sh2324prog.txt|url-status=dead|archive-date=2 May 2024|work=JTWC|accessdate=3 May 2024|date=3 May 2024}} Later that day, Hidaya peaked with 1-minute sustained winds of 80 knots.{{Cite JTWC|date=3 May 2024|type=prognostic|category=TC|designation=23S|no=5|name=Hidaya|time=15Z|url=https://www.metoc.navy.mil/jtwc/products/sh2324prog.txt|archive-url=https://web.archive.org/web/20240503143313/https://www.metoc.navy.mil/jtwc/products/sh2324prog.txt|archive-date=3 May 2024}} As it approached Tanzania, Hidaya was downgraded back into a severe tropical storm.

Signs of rapid weakening ensued as it moved inland. All agencies discontinued their advisories on May 4 as Hidaya further moved through landmass.

Hidaya was a rare example in recorded history of a tropical cyclone or depression making landfall in Tanzania, other examples being a cyclone passing over Zanzibar in 1872, an unnamed cyclone in 1952 and Tropical Depression Atang in 2002.{{Cite journal |last1=Msemo |first1=Hellen E. |last2=Finney |first2=Declan L. |last3=Mbuya |first3=Samwel I. |date=April 2022 |title=Forgotten accounts of tropical cyclones making landfall in Tanzania |url=https://eprints.whiterose.ac.uk/178892/12/Weather%20-%202021%20-%20Msemo%20-%20Forgotten%20accounts%20of%20tropical%20cyclones%20making%20landfall%20in%20Tanzania.pdf |journal=Weather |language=en |volume=77 |issue=4 |pages=127–131 |doi=10.1002/wea.3921 |bibcode=2022Wthr...77..127M |issn=0043-1656}}{{cite web | url=https://reliefweb.int/report/mozambique/fews-mozambique-food-security-update-19-nov-2002 | title=FEWS Mozambique Food Security Update: 19 Nov 2002 - Mozambique | ReliefWeb | date=19 November 2002 }} Additionally, it was the most intense recorded cyclone to occur in this region in the Indian ocean. Due to the storm, ferry service between Zanzibar and Dar es Salaam was temporarily halted. The cyclone struck after weeks of flooding across the region, adding to the destruction and death toll. Hidaya killed at least five people in Tanzania, including a fisherman from Pemba Island who drowned during the storm. The storm also damaged or destroyed 1,555 houses, while also washing out a portion of the Lindi-Dar es Salaam highway.

Within the South-West Indian Ocean, tropical and subtropical cyclones that are judged to have 10-minute sustained winds of 65 km/h (40 mph) by the Regional Specialized Meteorological Center on Réunion island, France (RSMC La Réunion) are usually assigned a name by the Sub-Regional Tropical Cyclone Advisory Centers in Mauritius and Madagascar. The Sub-Regional Tropical Cyclone Advisory Center (Mauritius Meteorological Services) in Mauritius names cyclones when they intensify into a moderate tropical storm between 55°E and 90°E, while the Sub-Regional Tropical Cyclone Advisory Center (Meteo Madagascar) in Madagascar names cyclones when they intensify into a moderate tropical storm between 30°E and 55°E. Storm names are taken from three pre-determined lists of names, which rotate on a triennial basis, with names used in the season being automatically removed. The new names this season are Alvaro, Belal, Candice, Djoungou, Eleanor, Filipo, Gamane, Hidaya, Ialy, and Jeremy which replaced Alicia, Bongoyo, Chalane, Danilo, Eloise, Faraji, Guambe, Habana, Iman, and Jobo in the 2020–21 season.{{RA I Tropical cyclone operational plan}}

If a tropical cyclone enters the South-West Indian basin from the Australian region basin (west of 90°E), it will retain the name assigned to it by the Bureau of Meteorology (BoM) or the Meteorology, Climatology, and Geophysical Agency (BMKG). The following storms were named in this manner:

This table lists all of the tropical and subtropical cyclones that were monitored during the 2023–2024 South-West Indian Ocean cyclone season. Information on their intensity, duration, name, areas affected, primarily comes from RSMC La Réunion, however, death and damage reports come from either press reports or the relevant national disaster management agency. The damage totals are given in 2023 or 2024 USD.
