2020–21 South Pacific cyclone season
The 2020–21 South Pacific cyclone season is the period of the year when most tropical cyclones form within the South Pacific Ocean to the east of 160°E. The season officially runs from November 1, 2020 to April 30, 2021, however a tropical cyclone could form at any time between July 1, 2020 and June 30, 2021 and would count towards the season total. During the season, tropical cyclones will be 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) will also monitor the basin and issue 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).

Storm names
Within the Southern Pacific a tropical depression is judged to have reached tropical cyclone intensity should it reach winds of 65 km/h, (40 mph) and it is evident that gales are occurring at least halfway around the center. With tropical depressions intensifying into a tropical cyclone between the Equator and 25°S and between 160°E - 120°W named by the RSMC Nadi. However should a tropical depression intensify to the south of 25°S between 160°E and 120°W it will be named in conjunction with RSMC Nadi by TCWC Wellington. Should a tropical cyclone move out of the basin and into the Australian region it will retain its original name. The next 10 names on the naming list are listed here below.[1]

Season effects
This table lists all the storms that developed in the South Pacific to the east of longitude 160°E during the 2019–20 season. It includes their intensity on the Australian tropical cyclone intensity scale, duration, name, landfalls, deaths, and damages. All data is taken from RSMC Nadi and/or TCWC Wellington, and all of the damage figures are in 2020 USD.
