In the middle of February, an area of convection persisted in the Mozambique Channel.

Subsequently, convection became more pronounced and Météo France classified the system as a tropical disturbance on February 18.{{cite web|work=RSMC La Réunion |publisher=Météo France |date=February 18, 2013 |accessdate=February 24, 2013 |title=Tropical Disturbance 9 Tropical Cyclone Forecast Warning |url=http://gwydir.demon.co.uk/advisories/WTIO30-FMEE_201302181248.htm |type=Report |archiveurl=https://archive.today/20130219082123/http://gwydir.demon.co.uk/advisories/WTIO30-FMEE_201302181248.htm |archivedate=February 19, 2013 |url-status=dead }} On February 19, the system attained gale-force winds and was upgraded to Moderate Tropical Storm Haruna.{{cite web|work=RSMC La Réunion |publisher=Météo France |date=February 19, 2013 |accessdate=February 24, 2013 |title=Moderate Tropical Storm Haruna Tropical Cyclone Forecast Warning |url=http://gwydir.demon.co.uk/advisories/WTIO30-FMEE_201302190641.htm |type=Report |archiveurl=https://archive.today/20130219082120/http://gwydir.demon.co.uk/advisories/WTIO30-FMEE_201302190641.htm |archivedate=February 19, 2013 |url-status=dead }} The structure of Haruna continued to become more symmetrical with a large radius of maximum winds, developing a ragged eye early on February 20.

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, whilst a name is normally only used once so thus far no names are retired.{{cite web|year=2010|title=Tropical Cyclone Operational Plan for the South-West Indian Ocean|accessdate=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}} For the first time this year tropical cyclones that move into this region from the Australian Region will not be renamed by the Sub-Regional Tropical Cyclone Advisory Center in Mauritius.

This table lists all of the tropical cyclones and subtropical cyclones that were monitored during the 2012–2013 South-West Indian Ocean cyclone season. Information on their intensity, duration, name, and areas affected, primarily comes from RSMC La Réunion.[http://www.meteo.fr/temps/domtom/La_Reunion/ Météo France (RSMC La Réunion)] {{webarchive |url=http://arquivo.pt/wayback/20090712010756/http%3A//www%2Emeteo%2Efr/temps/domtom/La_Reunion/ |date=July 12, 2009 }} Death and damage reports come from either press reports or the relevant national disaster management agency while the damage totals are given in 2012 USD.
