These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of 90°E and south of the Equator.

Tropical and subtropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion and unofficially by the Joint Typhoon Warning Center.

The cyclone weakened to a tropical storm south of Mayotte before rapidly strengthening back to Category 2 intensity, making landfall near Nacala at that strength on January 13.

In late January, Moderate Tropical Storm Elvis formed in the southern Mozambique Channel where it brought heavy rain to south-western Madagascar specifically in the Toliara Province but also the Morombe District.

On 8 August, the MFR noted that in mid-August, tropical cyclogenesis was possible near the equator due to a westerly wind burst expected to form during the active phase of the Madden–Julian oscillation (MJO).

[6] Soon after, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the disturbance, noting that despite being in an environment with high wind shear, it was intensifying.

[16] The JTWC would begin tracking the disturbance late on 30 September, noting that it was in an environment marginally favorable for development east-southeast off Diego Garcia.

[21] Ancha's cloud pattern would improve on 2 October, causing it to peak as a high-end moderate tropical storm with 10-minute sustained winds of 50 mph (85 km/h).

[22] However, the next day, Ancha's low-level circulation began being exposed due to moderate wind shear, extensive dry air, and steadily cooling sea surface temperatures, prompting the JTWC to issue their last warning on it.

[32] A developing central dense overcast and improving cloud pattern prompted the MFR to upgrade Bheki into a severe tropical storm early the next day.

[34][35] The Rodrigues Emergency Operations Command reported that 64 % of the population had been left without electricity due to power outages caused by strong winds.

Electricity company teams, military personnel and firefighters were dispersed across the territory to carry out necessary work, as well as clearing roads of fallen trees and branches, in order to return the situation to normal.

[39] On 9 December, the JTWC began issuing warnings for the system, classifying it as Tropical Cyclone 04S, as satellite imagery showed a partially exposed low-level circulation center on the eastern side of a developing burst of deep convection, which was nearly circular in shape and had cloud tops cooler than −80 °C (−112 °F).

[41] On the subsequent day, Chido rapidly deepened and intensified into an intense tropical cyclone within twelve hours, with its eye passing over Agalega and bringing extreme conditions to the island, where a minimum pressure of 980 hPa (28.94 inHg) was recorded.

[45] After reaching its peak intensity, the cyclone's eye, which was 13.8 miles (22.2 km) wide, became cloud-filled and increasingly ragged, and on 13 December, an eyewall replacement cycle occurred, causing the storm to weaken.

[46][47] Chido entered the Mozambique Channel on 14 December, with microwave imagery showing highly developed organized bands of deep convection.

[51] Shortly after landfall, the JTWC discontinued warnings,[52] and the MFR reported that Chido moved through Mozambique and Malawi, with convective activity gradually weakening.

Steered westward by a ridge to its south, the low had poorly organized convection at first, and the MFR designated it Zone of Disturbed Weather 5 on 6 January.

[56] On 9 January, Meteo-France upgraded the depression to Moderate Tropical Storm Dikeledi, after an increase in thunderstorms and a decrease in dry air.

Afterward, Dikeledi weakened back to tropical storm status while over land, emerging into the Mozambique Channel near Nosy-Be.

[60][61] While approaching the coast of Mozambique, the storm reattained tropical cyclone status on 13 January, making landfall in Nampula Province shortly thereafter.

[64] Accelerating to the southeast, Dikeledi strengthened back to tropical cyclone intensity on 15 January, due to warm waters and favorable conditions.

[69] The cyclone slightly weakened before intensifying back to Category 2 strength and made landfall near Nacala, Mozambique, causing six fatalities.

[70][71] The monsoon trough feeding the tropical system caused very strong rain bands over the Toliara Province with local accumulations of more than 500 millimetres (20 in) in 24 hours in the Morombe District.

New names this season are: Ancha, Bheki, Chido, Dikeledi, Elvis, Faida, Garance, Honde, Ivone, Jude, Kanto and Lira.

They replaced Ana, Batsirai, Cliff, Dumako, Emnati, Fezile, Gombe, Halima, Issa, Jasmine and Karim during the 2021–22 season, and also Letlama, which was not used, but the reason for its removal is unknown.
