The 2014–15 South Pacific cyclone season was a period of the year when most tropical cyclones form within the South Pacific Ocean, to the east of 160°E. The season officially ran from November 1, 2014 to April 30, 2015. During the season, tropical cyclones were officially monitored by the Regional Specialized Meteorological Center (RSMC) in Nadi, Fiji and the Tropical Cyclone Warning Centers in Brisbane, Australia and Wellington, New Zealand. The United States Armed Forces through the Joint Typhoon Warning Center (JTWC) also monitored the basin and issued unofficial warnings for American interests. RSMC Nadi attaches a number and an F suffix to tropical disturbances that form in or move into the basin while the JTWC designates significant tropical cyclones with a number and a P suffix. RSMC Nadi, TCWC Wellington and TCWC Brisbane all use the Australian Tropical Cyclone Intensity Scale and estimate windspeeds over a period of ten minutes, while the JTWC estimated sustained winds over a 1-minute period, which are subsequently compared to the Saffir–Simpson hurricane wind scale (SSHWS).
Ahead of the cyclone season, the Fiji Meteorological Service (FMS), Australian Bureau of Meteorology (BoM), New Zealand's MetService and National Institute of Water and Atmospheric Research (NIWA) and various other Pacific Meteorological services, all contributed towards the Island Climate Update tropical cyclone outlook that was released during October 2014. The outlook took into account the ENSO neutral conditions that had been observed across the Pacific and analogue seasons that had ENSO neutral and weak El Nino conditions occurring during the season. The outlook called for a near average number of tropical cyclones for the 2014–15 season, with eight to twelve named tropical cyclones, to occur between 135°E and 120°W compared to an average of 10. At least four of the tropical cyclones were expected to become category 3 severe tropical cyclones, while three could become category 4 severe tropical cyclones, they also noted that a Category 5 severe tropical cyclone was unlikely to occur. In addition to contributing towards the Island Climate Update outlook, RSMC Nadi and the BoM issued their own seasonal forecasts for the South Pacific region.
