2014–15 South-West Indian Ocean cyclone season#Tropical Storm Diamondra

During October 2014, the Mauritius Meteorological Services issued its seasonal outlook for the summer of 2014–15 and predicted that between ten and twelve named storms would develop during the season.{{cite web|date=October 10, 2014 |title=Summer 2014–2015 Outlook for Mauritius and Rodrigues |archive-url=https://web.archive.org/web/20140811064653/http://metservice.intnet.mu/climate-services/seasonal-climate-forecast.php |publisher=Mauritius Meteorological Services |url=http://metservice.intnet.mu/climate-services/seasonal-climate-forecast.php |archive-date=August 11, 2014 |access-date=October 15, 2014 |url-status=live }} The first tropical disturbance of the season developed on November 16, and quickly developed into the first named storm of the season and was named Adjali by Mauritius. The last tropical storm of this season, Tropical Depression 14, later known as Ikola, strengthened to a Category 1 tropical cyclone before it crossed on the Australian basin the next day. 2 storms, Bansi and Eunice, became Very Intense Tropical Cyclones.

An area of low pressure developed close to Diego Garcia on November 14. It slowly organized as it made a northwest–south-southeast loop over the next two days.

However, the MFR upgraded the depression into a moderate tropical storm, which was then named Glenda. It intensified slightly because of favourable conditions for further development, within moderate vertical wind shear. On February 25, the storm continued to intensify, and it reached peak intensity. It quickly weakened the next day, and continued to weaken on February 28, and it lost its energy on March 1. Thereafter, MFR announced their final advisory on the system soon after.{{cite web|title=Glenda (was 14S - South Indian Ocean)|url=https://www.nasa.gov/content/goddard/14s-south-indian-ocean/|publisher=NASA|access-date=29 November 2021|date=29 November 2021}}

On April 1, the MFR began to monitor Tropical Disturbance 13 several miles southeast of Diego Garcia. Post-storm analysis determined that it did not develop until April 2. Joalane rapidly intensified into a Tropical Cyclone strength system and reached peak intensity. Afterwards, Joalane kept strength while accelerating southward. Joalane became a remnant low late on April 11. The remnant low continued south until it degenerated to a trough by strong wind shear.{{cite web|title=Joalane (was 22S - Southern Indian Ocean)|url=https://www.nasa.gov/content/goddard/tropical-cyclone-22s-southern-indian-ocean|publisher=NASA|access-date=29 November 2021|date=29 November 2021}}

Within the South-West Indian Ocean, tropical depressions and subtropical depressions that are judged to have 10-minute sustained windspeeds of 65 km/h, (40 mph) by the Regional Specialized Meteorological Center on La Réunion Island, France (RSMC La Réunion) are usually assigned a name. However, it is the Sub-Regional Tropical Cyclone Advisory Centers in Mauritius and Madagascar who name the systems. The Sub-Regional Tropical Cyclone Advisory Center in Mauritius names the storm should it intensify into a moderate tropical storm between 55°E and 90°E, if the storm should intensify into a moderate tropical storm between 30°E and 55°E then the Sub-Regional Tropical Cyclone Advisory Center in Madagascar assigns the appropriate name to the storm. New name lists are used every year, while a name is normally only used once so there are currently no names are retired.{{cite web|year=2010|title=Tropical Cyclone Operational Plan for the South-West Indian Ocean|access-date=2012-06-07|author=Regional Association I Tropical Cyclone Committee|publisher=World Meteorological Organization|url=http://www.wmo.int/pages/prog/www/tcp/documents/TCP-12_2010_English.pdf}}

Of note is the presence of the name Nathan in this list. This is unrelated to Cyclone Nathan which coincidentally formed during the same cyclone season in the neighbouring Australian region.

This table lists all of the tropical cyclones and subtropical cyclones that were monitored during the 2014–2015 South-West Indian Ocean cyclone season. Information on their intensity, duration, name, areas affected, primarily comes from RSMC La Réunion. Death and damage reports come from either press reports or the relevant national disaster management agency while the damage totals are given in 2014 or 2015 USD.
