The 1995–96 South-West Indian Ocean cyclone season was a moderately active season that included Cyclone Bonita, which was the first known tropical cyclone to cross from the southern Indian Ocean into the southern Atlantic Ocean. Tropical activity lasted for about six months from the middle of November 1995 to early May 1996. The first storm, Intense Tropical Cyclone Agnielle, formed in the adjacent Australian basin on November 16 and later reached peak winds in the south-west Indian Ocean. The next named storm after Agnielle was Bonita, which formed in early January and killed 42 people. The basin was most active in February, with two tropical cyclones, or the equivalent of a minimal hurricane, as well as a severe tropical storm. The first of these three was Doloresse, which killed 67 people due to a shipwreck in the Comoros. The next storm was Cyclone Edwige, which caused heavy crop damage on Mauritius before looping along the east coast of Madagascar. In March, both Cyclone Flossy and Tropical Storm Guylianne passed near the Mascarene Islands, producing heavy rainfall and gusty winds.
The 2006–07 South-West Indian Ocean cyclone season featured the second-most intense tropical cyclones for a season in the tropical cyclone basin, only behind the 2018–19 season. The basin contains the waters of the Indian Ocean south of the equator and west of 90°E. Météo-France's meteorological office in Réunion (MFR), the official Regional Specialized Meteorological Center for the South-West Indian Ocean, tracked 15 tropical disturbances, of which eleven attained gale-force winds. The season began in October 2006 with a short-lived tropical disturbance, followed by Anita in November, which was the first named storm of the season. Cyclone Bondo was the first of six intense tropical cyclones, which took a rare track through the southern Seychelles before making landfall on northwest Madagascar, killing 11 people. Severe Tropical Storm Clovis lasted from December 2006 to January 2007; it struck eastern Madagascar, killing four people.
The 2004–05 South-West Indian Ocean cyclone season was a near average season, despite beginning unusually early on August 30 with the formation of an early-season tropical depression. Météo-France's meteorological office in Réunion (MFR) ultimately monitored 18 tropical disturbances during the season, of which 15 became tropical depressions. Two storms – Arola and Bento – formed in November, and the latter became the most intense November cyclone on record. Bento attained its peak intensity at a low latitude, and weakened before threatening land. Tropical Cyclone Chambo was the only named storm in December. In January, Severe Tropical Storm Daren and Cyclone Ernest existed simultaneously. The latter storm struck southern Madagascar, and five days later, Moderate Tropical Storm Felapi affected the same area; the two storms killed 78 people and left over 32,000 people homeless. At the end of January, Severe Tropical Storm Gerard existed as an unnamed tropical storm for 18 hours due to discrepancies between warning centers.
The 2003–04 South-West Indian Ocean cyclone season featured the most intense tropical cyclone in the South-West Indian Ocean, Cyclone Gafilo, as well as nine other named storms. Tropical activity began on September 28 when Moderate Tropical Storm Abaimba formed at a low latitude. Activity continued until late May, following Severe Tropical Storm Juba, which marked the third year in a row that a storm formed in May. The final disturbance, one of sixteen, dissipated on May 24. Activity was near average, and the season was one of the longest on record.
The 2002–03 South-West Indian Ocean cyclone season was one of the longest lasting and the third-most active season in the South-West Indian Ocean. Storms during the season impacted the Mascarene Islands, Seychelles, Madagascar, and countries in south-eastern Africa. The season began early when an unnamed tropical storm struck Seychelles in September, becoming the most damaging storm there in 50 years. The next system, Atang, was the first named storm of the season, but was only a tropical depression; it was named due to the threat to an outer island of Mauritius. Atang later struck Tanzania in a climatologically unusual area in November, resulting in unconfirmed deaths of fishermen. The first named storm to reach tropical storm intensity was Boura, which brushed the Mascarene Islands with gusty winds and rainfall. In December, Cyclone Crystal threatened to strike Mauritius but instead veered eastward, and later, Tropical Storm Delfina lasted from late December through early January 2003. Delfina damaged or destroyed thousands of houses in Mozambique and Malawi, killing 54 people.
The 2001–02 South-West Indian Ocean cyclone season had the earliest named storm since 1992. Many storms formed in the north-east portion of the basin, and several more originated around Australia. The basin is defined as the waters of the Indian Ocean west of longitude 90°E to the coast of Africa and south of the equator. Eleven tropical storms formed, compared to an average of nine. Tropical systems were present during 73 days, which was significantly higher than the average of 58 for this basin.
The 1998–99 South-West Indian Ocean cyclone season was a quiet season that had the fourth-lowest number of days with tropical storm or tropical cyclone activity. Most of the storms formed either in the Mozambique Channel or in the far eastern portion of the basin, with five storms crossing from the adjacent Australian basin east of 90° E. As a result, few storms impacted Madagascar, and none made landfall on the African continent. Throughout most of the season, there was below-normal sea surface temperatures in the Indian Ocean east of Madagascar. In February, typically the peak in activity, Réunion island recorded its highest average monthly pressure since 1953. Due to generally unfavorable conditions, there were only six tropical storms tracked by the Météo-France office (MFR) on Réunion. There were only two tropical cyclones – a storm with winds of at least 120 km/h (75 mph).
Intense Tropical Cyclone Kalunde was the strongest storm of the 2002–03 South-West Indian Ocean cyclone season. The eleventh named storm and sixth cyclone of the season, Kalunde formed on March 4 from an area of disturbed weather east-southeast of Diego Garcia. The storm steadily strengthened and attained severe tropical storm intensity on March 6. After starting a phase of rapid deepening, Kalunde attained cyclone intensity the next day. Kalunde attained its peak intensity on March 8, as an intense tropical cyclone. It maintained its peak strength for a day; shortly thereafter, the system began to weaken. After undergoing an eyewall replacement cycle, the storm brushed Rodrigues. Shortly after doing so, Kalunde weakened into a tropical cyclone and later a severe tropical storm. Two days later, on March 16, the cyclone transitioned into an extratropical cyclone and dissipated the next day.
The 1990–91 South-West Indian Ocean cyclone season was fairly quiet, although activity began early and the final named storm formed at a record late date. There were seven named storms classified by the Météo-France office (MFR) on Réunion, as well as three depressions; an additional depression was classified by the Joint Typhoon Warning Center (JTWC), an unofficial warning agency. The JTWC tracked storms in both September and October, although neither affected land. In late November, another short-lived depression formed in the northeastern portion of the basin. Activity remained minimal until January, when Tropical Storm Alison formed in the eastern portion of the basin. Later in the month, Cyclone Bella became the strongest storm of the season, reaching 10‑minute maximum sustained winds of 155 km/h (96 mph). It passed near the island of Rodrigues, becoming the worst cyclone there in 20 years and killing half of the population of one endangered species. Bella also likely caused a cargo ship to go missing with 36 people on board. Three storms developed in short succession in the second half of February. Cyclone Cynthia developed rapidly in the Mozambique Channel on February 16 and struck western Madagascar, killing 36 people and ruining local rice harvests. A residual trough after Cynthia dissipated spawned Tropical Storm Debra, which looped in the Mozambique Channel. Toward the end of the month, Tropical Storm Elma exited the basin into the adjacent Australian region, only to re-enter the south-west Indian Ocean and dissipate. Long-lived Cyclone Fatima originated in the Australian basin in late March and changed directions before becoming extratropical. On April 2, a tropical depression struck eastern Madagascar, killing 18 people. The final storm, Gritelle, was named on June 10, the latest on record.
The 1991–92 South-West Indian Ocean cyclone season was an average cyclone season in which most storms remained over open waters. At the time, the season's official bounds lasted from November 15, 1991, to April 30, 1992, although this season began early when three tropical depressions formed before the official start. The second, designated Tropical Depression A2 by the Météo-France office (MFR) on Réunion, passed north of Madagascar on October 16 before weakening.
The 1992–93 South-West Indian Ocean cyclone season lasted longer than normal, with the first storm Aviona forming on September 27 and the final storm Konita not dissipating until May 7. It was an above-average season, with four tropical cyclones – the equivalent of a minimal hurricane – along with six tropical storms, one subtropical depression, and several depressions including one that was named. The basin is defined as the area west of 90°E and south of the Equator in the Indian Ocean, which includes the waters around Madagascar westward to the east coast of Africa. Tropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion (MFR), as well as by the Joint Typhoon Warning Center (JTWC).
The 1984–85 South-West Indian Ocean cyclone season was an average cyclone season. Tropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion. The first storm formed in mid-November, though it was not officially named. A few days later, the first official storm of the year (Anety) formed. In December, one storm formed. During January 1985, two tropical cyclones formed towards the end of the month. Three more systems developed in a short period of time in early to mid-February. After nearly two more months of inactivity, an unusually powerful late season storm developed (Helisaonina) in mid-April, which was the strongest storm of the year. While a number of storms during the season reached severe tropical storm status, only one of those intensified further. Even though two tropical cyclones this year made landfall, no known damage was recorded.
The 1982–83 South-West Indian Ocean cyclone season was the least active cyclone season in the basin since 1961–1962. There were six systems that were named, although three of them – Arilisy, Clera, and Fely – failed to intensify beyond tropical depression status. No storms reached tropical cyclone status, according to the official warning agency for the basin, Météo-France, although the two strongest storms – Bemany and Elinah – peaked just below that intensity. The first named storm, Arilisy, formed on October 27, and dissipated without having affected land. However, the Joint Typhoon Warning Center (JTWC), which is an unofficial warning center for the basin, briefly tracked a tropical depression in July. The next storm was Bemany, which passed east of Mauritius near peak intensity in early December. Tropical Depression Clera existed briefly in the middle of September, and Tropical Storm Dadafy moved across the eastern portion of the basin in late December.
The 1988–89 South-West Indian Ocean cyclone season was an active season that featured several storms moving near or over the Mascarene Islands or Madagascar. The eleven tropical storms was two greater than average, of which five became tropical cyclones – a storm with maximum sustained winds over 10 minutes of 120 km/h (75 mph) or greater. Storms were monitored by the Météo-France office (MFR) on Réunion island in an official capacity, as well as the American Joint Typhoon Warning Center (JTWC) on an unofficial base. The season began early with Moderate Tropical Storm Adelinina forming in early November, and continued through the middle of April. Adelinina was one of two storms to form in November, the other being Tropical Cyclone Barisaona which crossed from the adjacent Australian basin.
The 1986–87 South-West Indian Ocean cyclone season was below average due to an ongoing El Niño and a weak monsoon that suppressed convection and storms. There were only five named storms tracked by the Météo-France office (MFR) on Réunion. The United States–based Joint Typhoon Warning Center (JTWC) followed four other storms in the basin, which is the waters of the Indian Ocean south of the equator and west of 90° E to the coast of Africa. The JTWC tracked a storm on August 1 in the northeastern portion of the basin, unusual for the time of year. The first named storm was Severe Tropical Storm Alinina, which originated from the Intertropical Convergence Zone east of Madagascar in the middle of January. However, there was an unnamed tropical depression that produced heavy rainfall in Réunion and Madagascar, causing two deaths in the latter country.
The 1985–86 South-West Indian Ocean cyclone season was the first in which the Météo-France office (MFR) on Réunion tracked cyclones as far east as 90° E in Indian Ocean, south of the equator. Previously, the agency's area of responsibility was limited to 80° E. It was an active season with twelve named storms, of which five strengthened into tropical cyclone with 10 minute sustained winds of at least 120 km/h (75 mph). The first named storm was Tropical Storm Alifredy, which originated in the Mozambique Channel in late December and moved across Madagascar. However, the unofficial Joint Typhoon Warning Center (JTWC) tracked a short-lived storm in September.
The 1993–94 South-West Indian Ocean cyclone season was the most active season in the basin since the start of reliable satellite coverage in 1967, until the record was surpassed 25 years later in the 2018–19 South-West Indian Ocean cyclone season. Activity lasted from mid-November, when Moderate Tropical Storm Alexina formed, until mid-April, when Tropical Cyclone Odille became extratropical. Four tropical cyclones – Daisy, Geralda, Litanne, and Nadia – struck eastern Madagascar, of which Geralda was the costliest and deadliest. With gusts as strong as 350 km/h (215 mph) accompanied by heavy rainfall, Geralda destroyed more than 40,000 homes and left 356,000 people homeless. Geralda killed 231 people and caused more than $10 million in damage. Cyclone Nadia was the second deadliest cyclone, having killed 12 people in northern Madagascar and later severely damaging portions of northeastern Mozambique, killing about 240 people and leaving $20 million in damage in the latter country. In February, Cyclone Hollanda struck Mauritius near peak intensity, causing $135 million in damage and two deaths.
The 1994–95 South-West Indian Ocean cyclone season was fairly active, with storms forming regularly from October through April. It was much less damaging than its predecessor, and most of the storms in the season remained over water or only brushed land. The first system was Tropical Depression A1, which formed in October and passed north of Madagascar. The first named storm was Albertine, which formed on November 23 in the northeastern portion of the basin and became one of three intense tropical cyclones. The last storm was Marlene, which was also an intense tropical cyclone and dissipated on April 11.
The 2014–15 South-West Indian Ocean cyclone season was an above average event in tropical cyclone formation. It began on November 15, 2014, and ended on April 30, 2015, with the exception for Mauritius and the Seychelles, for which it ended on May 15, 2015. 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.
Tropical Storm Clotilda was a destructive tropical cyclone that inundated Réunion in February 1987. A tropical disturbance first formed between Madagascar and Réunion on February 9 and slowly intensified thereafter. While meandering, the storm fluctuated in intensity before it reached its peak intensity on February 13, with winds of 110 km/h (70 mph). After passing near Réunion, it began to weaken. On February 16, however, Clotilda began to regain strength, and reached its secondary peak on February 17. Two days later, Clotilda became an extratropical cyclone. By February 22, Clotilda was no long being tracked by meteorologists. While active, it brought torrential rains to the island of Réunion during a span of 72 hours. A total of 1,855 mm (73.0 in) of rain was recorded in La Plaine-des-Palmistes; rainfall totals occasionally exceeded the totals measured during Cyclone Hyacinthe, the last major storm to affect Réunion. However, the peak total measured in Hyacinthe was lower than the total measured during Clotilda. Furthermore, about 250 homes were damaged and roughly 120 homes were destroyed. Eighty-nine trees were also brought down during the storm. Throughout the island, damage totaled $2 million (1987 USD) and 10 people were killed. In addition to the destruction on Réunion, 5% of crops on Mauritius were impacted by the storm. During the aftermath of the cyclone, 1,000 people on Réunion were evacuated to shelters.
