The 2022–23 South-West Indian Ocean cyclone season was one of the deadliest South-West Indian cyclone seasons on record, mostly due to Cyclone Freddy. It officially began on 15 November 2022, and ended on 30 April 2023, with the exception for Mauritius and the Seychelles, for which it ended on 15 May 2023. 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. However, tropical cyclones can form year-round, and all tropical cyclones that form between 1 July 2022 and 30 June 2023 will be part of the season. 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.

Extremely Severe Cyclonic Storm Mocha was a powerful and deadly tropical cyclone in the North Indian Ocean which affected Myanmar and parts of Bangladesh in May 2023. The second depression and the first cyclonic storm of the 2023 North Indian Ocean cyclone season, Mocha originated from a low-pressure area that was first noted by the India Meteorological Department (IMD) on 8 May. After consolidating into a depression, the storm tracked slowly north-northwestward over the Bay of Bengal, and reached extremely severe cyclonic storm intensity. After undergoing an eyewall replacement cycle, Mocha rapidly strengthened, peaking at Category 5-equivalent intensity on 14 May with winds of 280 km/h (175 mph), tying with Cyclone Fani as the strongest storm on record in the North Indian Ocean in terms of 1-minute sustained winds. Mocha slightly weakened before making landfall, and its conditions quickly became unfavorable. Mocha rapidly weakened once inland and dissipated shortly thereafter.
