Tropical Cyclone Tony

On 26 August, the BoM reported that a tropical low had developed on a shear line about Шаблон:Convert to the northwest of Cocos Island. Over the next couple of days the depression gradually developed further before at 1800 UTC on 27 August, TCWC Perth estimated that it had become a tropical cyclone and named it Tony. During the next couple of days, the system moved towards the west-southwest before on 29 August it reached its peak intensity of Шаблон:Convert and a peak pressure of Шаблон:Convert as it approached the edge of TCWC Perth's area of responsibility. During the next day, Tony moved into the South West Indian Ocean and weakened gradually before it dissipated during 31 August. Neither the Mauritius or Reunion meteorological services monitored Tony as a tropical cyclone while it was active, while it was not included in the JTWC's analysis of the season.

Intense Tropical Cyclone Albine

Шаблон:Infobox hurricane small Albine existed from 25 November to 6 December.

Intense Tropical Cyclone Viola–Claudette

Шаблон:Infobox hurricane small Cyclone Viola entered the basin on December 18 from the Australian region, whereupon it became Cyclone Claudette. After passing southeast of St. Brandon, Claudette struck Mauritius on December 22, producing wind gusts of Шаблон:Convert. The storm caused 5 fatalities, 257 injuries, and US$175 million in damage on the island. About 5,000 houses were destroyed or severely damaged. Effects on neighboring Réunion were limited to Шаблон:Convert wind gusts and some rainfall.

Moderate Tropical Storm Berenice

Шаблон:Infobox hurricane small Berenice existed from 15 December to 21 December.

Tropical Depression Wilf–Danitza

Шаблон:Infobox hurricane small Wilf-Danitza existed from 23 December 1979, to 3 January 1980.

Intense Tropical Cyclone Hyacinthe

Шаблон:Infobox hurricane small Шаблон:Main Hyacinthe formed on January 15, 1980, to the northeast of Mauritius in the southern Indian Ocean. Initially it moved to the west-southwest, and while slowly intensifying it passed north of the French overseas department of Réunion. On January 19, Météo-France estimated that the storm had intensified to a tropical cyclone. Hyacinthe looped to the south of eastern Madagascar and weakened, although it restrengthened after turning to the east. The storm executed another loop to the southwest of Réunion, passing near the island for a second and later third time. Hyacinthe became extratropical on January 29 after turning southward, dissipating two days later.

Tropical Cyclone Hyacinthe set several worldwide tropical cyclone rainfall records in Réunion in the Southwestern Indian Ocean, including a peak total of 5678 mm (223.5 inches). For twelve days, Hyacinthe dropped torrential rainfall on Réunion; nearly all of the island received more than 1 m (3.3 ft) of precipitation. Over a 15‑day period from January 14 to January 28, Шаблон:Convert of rainfall were recorded at Commerson's Crater, a volcano. The heaviest rainfall occurred through a process called orographic lift in the mountainous interior, leading to hundreds of landslides. Widespread floods washed out roads and isolated three villages. Hyacinthe caused heavy damage to crops and damaged or destroyed 2,000 houses. Losses from the storm totaled $167 million (1980 USD, 676 million francs), and 25 people were killed.

Intense Tropical Cyclone Jacinthe

Шаблон:Infobox hurricane small Jacinthe existed from 1 February to 7 February. On February 3, the cyclone passed between Mauritius and Rodrigues, producing wind gusts of Шаблон:Convert and Шаблон:Convert on the respective islands.
