South Pacific tropical cyclone seasons 2001–02, 2002–03, 2003–04, 2004–05, 2005–06 |
The 2003–04 South Pacific cyclone season was a below-average season with only three tropical cyclones occurring within the South Pacific to the east of 160°E. The season officially ran from November 1, 2003 to April 30, 2004 with the first disturbance of the season forming on December 4 and the last disturbance dissipating on April 23.[A 1][A 2] This is the period of the year when most tropical cyclones form within the South Pacific Ocean.[1]
During the season at least 16 people were killed from tropical disturbances whilst overall damage was estimated at $218 million (2004 USD; $352 million 2024 USD). The most damaging tropical disturbance was Cyclone Heta which caused at least $211 million (2004 USD; $340 million 2024 USD) in damage to six different countries and left three dead.[2][3][4] The deadliest tropical disturbance of the season was Tropical Depression 10F, which was responsible for eleven deaths and caused $2.74 million (2004 USD) in damage.[5] Cyclone Ivy also caused 2 deaths and caused $4.17 million (2004 USD; $6.73 million 2024 USD) worth of damage to Vanuatu.[2][6] As a result of the impacts caused by Heta and Ivy, the names were retired from the tropical cyclone naming lists.[1]
Within the South Pacific, tropical cyclones are monitored by the Regional Specialized Meteorological Center (RSMC) in Nadi, Fiji, and the Tropical Cyclone Warning Center (TCWC) in Wellington, New Zealand. RSMC Nadi attaches a number and an F suffix to tropical disturbances that form in or move into the South Pacific. The United States Joint Typhoon Warning Center (JTWC) issues unofficial warnings within the South Pacific, designating tropical cyclones with a number and a P suffix. RSMC Nadi and TCWC Wellington both use the Australian Tropical Cyclone Intensity Scale, and measure windspeeds over a period of ten minutes, while the JTWC measures sustained winds over a period of one minute and uses the Saffir–Simpson Hurricane Scale.

Severe Tropical Cyclone Heta
Category 5 severe tropical cyclone (Australian scale) | |
Category 5 tropical cyclone (SSHWS) | |
![]() ![]() | |
Duration | December 28 – January 7 |
---|---|
Peak intensity | 215 km/h (130 mph) (10-min); 915 hPa (mbar) |
Cyclone Heta developed in the South Pacific Ocean and reached cyclone-force winds on January 1, 2004. It struck the island of Niue with a much more direct blow on January 6. Heta's eyewall hit Niue almost exactly at the height of the storm's power. It caused extensive property damage throughout the island, and two people were killed. Efforts to rebuild from the storm in Niue lasted almost the entire year of 2004.
Heta caused American Samoa to declare a state of emergency (officially a "Declaration of Emergency" in American Samoan law) on January 7, and even though officially the storm never made landfall there, it necessitated the emergency evacuation of 140 people and was responsible for property damage.[7]
The nation of Tonga was also affected by Heta, as the winds swept away trees that were needed for the country's food supply. However, Tonga did not receive a direct hit or suffer such extensive loss as Niue.

During April 11 a weak tropical low moved into the South Pacific basin from the Australian region, and was designated as Tropical Disturbance 13F by RSMC Nadi later that day.[12] 13F was last noted on April 13 as a Tropical Depression.
Other systems
The first numbered tropical disturbance of the season developed within a large area of atmospheric convection on December 4, to the northwest of the Fijian dependency of Rotuma.[16] During that day the depression slowly moved west, before it was classified as a weak tropical depression during the next day.[17][18] The system subsequently weakened and lost its organisation because of moderate to strong vertical windshear and was last noted during December 6.[19][20]
Tropical Disturbance 02F was first noted by the FMS during December 16, within an environment conducive for further development, about 340 km (210 mi) to the west of Honiara in the Solomon Islands.[21][22] Over the next few days, the system remained poorly organised and slow-moving within an area of moderate vertical windshear, before it was last noted by the FMS during December 20, as it entered the Australian region.[23][24] Tropical Disturbance 04F was subsequently first noted within a broad area of low pressure by the FMS, while it was located on the border with the South Pacific basin, about 100 km (60 mi) to the south of Honiara in the Solomon Islands.[25] The system was located in a moderate area of vertical windshear and was poorly organised with atmospheric convection confined to the system's eastern semicircle.[25] The system subsequently moved south-eastwards and remained poorly organised, before it was last noted by the FMS later that day while it was located to the south of San Cristobal Island.[26]
During April 6, the FMS reported that Tropical Depression 11F had developed within a monsoon trough, about 140 km (85 mi) to the north-east of Suva in Fiji.[27][28] Over the next day, the system moved south-eastwards towards Tonga, before it was last noted by the FMS later that day, while it was located about 300 km (185 mi) to the southwest of Tongatapu in Tonga.[28][29][12]
On April 18, RSMC Nadi reported that Tropical Disturbance 14F had developed within the monsoon trough, about 515 km (320 mi) to the northeast of Nukuʻalofa in Tonga.[12][30] During that day, the disturbance moved through the Tongan archipelago, before it was last noted later that day.[12]
During April 22, the FMS reported that Tropical Disturbance 15F had developed around 500 km (310 mi) to the northeast of Honiara in the Solomon Islands.[31] Over the next couple of days, the system remained poorly organised and near stationary to the northeast of the Solomon Islands, before it was last noted during April 24.[12][32]
