In 2021, tropical cyclones have formed in six major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones will be assigned names by various weather agencies if they attain maximum sustained winds of 35 knots (65 km/h; 40 mph). During this year, 114 systems have formed and 67 were named, including one subtropical depression and excluding one system which was unofficial. So far, the most intense storm of the year was Typhoon Surigae, with maximum 10-minute sustained wind speeds of 220 km/h (140 mph) and a minimum pressure of 895 hPa (26.43 inHg). The deadliest tropical cyclone so far was Cyclone Seroja, which caused 272 fatalities in Indonesia, while the costliest so far was Hurricane Ida, which caused an estimated $50 billion USD in damage after striking Louisiana and the Northeastern United States.
Tropical cyclones are primarily monitored by a group of ten warning centers, which have been designated as a Regional Specialized Meteorological Centre (RSMC) or a Tropical Cyclone Warning Center (TCWC) by the World Meteorological Organization. These are the United States National Hurricane Center (NHC) and Central Pacific Hurricane Center, the Japan Meteorological Agency (JMA), the Indian Meteorological Department (IMD), Météo-France (MFR), Indonesia's Badan Meteorologi, Klimatologi, dan Geofisika, the Australian Bureau of Meteorology (BOM), Papua New Guinea's National Weather Service, the Fiji Meteorological Service (FMS) as well as New Zealand's MetService. Other notable warning centers include the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA), the United States Joint Typhoon Warning Center (JTWC), and the Brazilian Navy Hydrographic Center.

The La Niña from the previous year persisted into 2021,[1] though by March and April it had begun to weaken.[2][3] On May 13, the National Oceanic and Atmospheric Administration assessed that the El Niño–Southern Oscillation (ENSO) transitioned into its neutral phase.[4] Two systems, Tropical Depression 05 and Severe Tropical Storm Danilo persisted into 2021 after developing within the South-West Indian Ocean during December 2020. The COVID-19 pandemic disrupted responses and recovery in areas affected by tropical cyclones.[5][6]
Summary[]
North Atlantic Ocean[]
On May 22, a subtropical storm formed east of Bermuda, with the NHC assigning it the name Ana. The formation of Ana marked the seventh consecutive year in which a named storm formed before the official start date in the North Atlantic basin. Later on May 23, Ana transitioned into a tropical storm. Soon thereafter, the storm encountered unfavorable conditions, which resulted in its dissipation by the next day. On June 14, a non-tropical low offshore the coast of North Carolina quickly intensified to a tropical storm, being assigned the name Bill by the NHC. On June 11, a low-pressure area formed in the Gulf of Mexico. The low-pressure area started moving over favorable conditions, which prompted the NHC to mark the system as Potential Tropical Cyclone Three. The system gradually intensified into a tropical storm and was given the name Claudette before making landfall on the Louisiana coast. It then entered into the Atlantic Ocean on June 22, before dissipating by the same evening. On 28 June, a low pressure area rapidly intensified into Tropical Storm Danny despite being present in unfavorable high pressure area. It made landfall over South Carolina and dissipated by the next day. On July 1, another tropical depression has formed in the Atlantic's Main Development Region (MDR), and it further intensified into Tropical Storm Elsa by the same evening. Elsa later intensified into a category 1 hurricane. The storm made landfall in Cuba on July 5 with winds of 60 mph and a pressure of 1007 mb. The storm passed by The Florida Keys the following day with the same windspeed of 60 mph. Elsa later intensified to 70 mph, a high-end tropical storm. Elsa later became a low-end category 1 hurricane. The storm weakened down to a tropical storm that night and continued to weaken until it made landfall in Florida. Elsa made landfall in Florida the following day with winds of 65 mph and a pressure of 999 mb. Elsa moved into Georgia as a tropical storm.
Eastern & Central Pacific Oceans[]
On May 9, a tropical depression formed in the Eastern Pacific, with the NHC giving it the designation One-E. A few hours later, it strengthened into a tropical storm, being given the name Andres; Andres was the earliest named storm in the Eastern Pacific that formed east of 140°W, having formed 12 hours earlier before the previous record holder. The storm remained weak and dissipated on 11 May as it encountered high wind shear. Its outer bands caused moderate rainfall over the country of Mexico. In late May, another tropical depression formed and was later named Blanca as it strengthened into a tropical storm. However it dissipated on June 4 due to hostile conditions. On June 2 a low-pressure area was expected to develop into a tropical depression, however unfavorable conditions hindered its progress and the NHC stopped monitoring the system. On June 10, the low-pressure area began to once again organize over favorable conditions, and on June 12, the NHC designated it as Three-E. Six hours later it intensified into a tropical storm and was named Carlos. On June 14, Carlos weakened to a tropical depression as it became increasingly devoid of any convection. On June 15, a broad low-pressure system formed several miles offshore of southwestern Mexico. The low gradually organized, and on June 18, it was upgraded to a tropical depression, being given the designation Four-E. On the same day, it further intensified into a tropical storm and was given the name Dolores. Dolores made landfall on the southwestern coast of Mexico and rapidly weakened into a remnant low on June 20. Five days later, Tropical Storm Enrique formed on the same location and rapidly intensified into a hurricane by the next day becoming the season's first hurricane. Its outer bands brought heavy rainfall and landslides over the same places in Mexico where Tropical Storm Dolores affected earlier. On 30 June, the storm weakened to a low pressure area due to unfavourable conditions in the Gulf of California and made landfall over the Baja California peninsula and dissipated soon thereafter. On July 14, a tropical depression formed, not too long later, it was named Felicia. Felicia started to intensify. The storm became a hurricane the following day. Later that day, Felicia became a category 2 hurricane. The next day the storm became a category 3 major hurricane. The storm intensified until becoming a category 4 hurricane later that day. The storm stopped intensifying until Felicia intensified to 145MPH the next day. Tropical Depression Seven-E formed the same day and intensified into Tropical Storm Guillermo. A pair of tropical depressions formed on July 30, one of which intensified into Tropical Storm Hilda. The other tropical depression dissipated but a few days after that, reformed and later became Tropical Storm Jimena. On August 7, a tropical depression formed and later on in the day it intensified into Tropical Storm Kevin.
Western Pacific Ocean[]
On January 19, a tropical depression formed, becoming the first Northern Hemisphere tropical cyclone of the year and of the 2021 Pacific typhoon season. It brought minor damage to the Philippines. On February 16, another system formed, with the PAGASA giving it the name Auring and the JTWC designating the system as 01W. On February 17, it was named Dujuan by the JMA. After passing over Palau, it brought minor damage to the Philippines before dissipating on February 22. On March 14, a tropical depression formed near the Sulu Sea, though it was short-lived and it quickly degenerated back into a low-pressure area. On April 12, a tropical depression formed south of Woleai, and on the next day, the JMA upgraded it to a tropical storm, giving it the name Surigae. On April 16, it was given the name Bising by the PAGASA as it entered the Philippine Area of Responsibility. Surigae underwent rapid intensification, becoming the strongest tropical cyclone to form before May in the Northern Hemisphere. After bringing severe damages to the Philippines, it transitioned into an extratropical cyclone on April 24 and dissipated on April 30. On May 12, the JTWC began tracking a tropical depression, giving it the designation 03W with the PAGASA assigning it the local name Crising. It made landfall on the Philippines as a weak tropical storm, however damage was minimal due to the storm's small size. Two tropical depressions formed near Palau on May 29 and May 30 respectively, with the former being assigned the name Choi-wan by the JMA. Choi-wan moved through the Philippines before merging with the Meiyu front on June 4. After a week gap on June 11, another tropical depression formed over the South China Sea and it intensified further to a tropical storm named as Koguma. However, it remained short lived and made landfall over the nation of Vietnam by the next day and soon dissipated thereafter. After 10 days on June 21, Tropical Storm Champi formed. As a tropical depression, it affected the Mariana Islands and Guam before intensifying into a weak typhoon. It became extratropical on 27 June. A tropical depression with its Filipino name, Emong, formed a couple hundred miles from Mainland China. The storm remained a tropical depression and later dissipated. Another tropical depression formed near Vietnam a couple days later, the storm later made landfall in the country as a weak tropical depression. A tropical depression formed later in the month having the Filipino name Fabian.
North Indian Ocean[]
On April 2, a tropical depression formed in the north Andaman Sea near the Myanmar coast. It remained short-lived, however, dissipating the next day. It was the fourth system to form within the first fifteen days of April since the satellite era began in 1960. Formation during this time is considered rare since the first storm of a season usually forms in mid-April or May. A month later, on May 14, another tropical depression formed in the Arabian Sea. Later that day, it intensified into a cyclonic storm, being assigned the name Tauktae by the IMD. It intensified to an extremely severe cyclonic storm and made landfall on Gujarat. Ten days later another tropical depression formed in the Bay of Bengal in May 23, before strengthening into a cyclonic storm and receiving the name Yaas. It rapidly intensified further to a very severe cyclonic storm and made landfall in Odisha. Both of these storms caused considerable loss of lives and damage.
South-West Indian Ocean[]
January - June[]
From the 2020 season, two systems crossed into the 2021 season after having formed during the previous year. The systems were Danilo, which peaked as a high-end severe tropical storm and briefly passed near the Mascarene Islands, and a tropical depression designated as 05 which entered the South-West Indian Ocean basin on December 28, causing a Fujiwhara effect with Danilo before dissipating on January 3. In the 2021 season, a tropical disturbance formed in the South-West Indian Ocean, which intensified into a tropical storm, being given the name Eloise. After making landfall on Madagascar, it rapidly intensified into a tropical cyclone in the Mozambique Channel before making a second landfall on Beira. Its remnants affected Zimbabwe, Eswatini, and South Africa. Joshua entered the basin from the Australian Region on the same day. On January 27, 10U from the Australian region entered the basin and was designated as Tropical Depression 09 before quickly dissipating thereafter.
On February 4, a tropical depression formed and intensified into a tropical cyclone named Faraji which further intensified into the season's first intense and very intense tropical cyclone. On February 10, a subtropical depression intensified into a tropical cyclone, being named Guambe and peaking as a Category 2 equivalent tropical cyclone. On March 1, Marian briefly entered the basin before exiting the basin the next day. On March 2, two tropical disturbances formed, and both intensified, being given the names Habana and Iman respectively. While Iman peaked as a moderate tropical storm and then dissipated, Habana continued to intensify and became the season's second intense tropical cyclone. After a short period of inactivity, a tropical depression designated as 15 formed on March 25, though it remained weak and dissipated by March 28.
On April 10, a low-pressure area formed, but due to unfavorable conditions, development was limited. By April 19, the low-pressure area intensified into a tropical depression. The tropical depression intensified shortly into a moderate tropical storm earning the name Jobo. It then rapidly intensified into a tropical cyclone before weakening due to an increase in wind shear, dissipating on April 24. Its remnant made landfall on Tanzania, causing little damages in the area.
July - December[]
Australian region[]
January - June[]
At the beginning of the 2021 season, a new tropical low formed in the Australian region near the Northern Territory of Australia, which further intensified into the first named cyclone of 2021, being given the name Imogen before making landfall on Far North Queensland. Another tropical low formed northeast of the Cocos Islands which lasted for five days and dissipated on January 10. Joshua formed on January 13 and crossed into the South-West Indian Ocean basin four days later. A new tropical low formed on January 16 near Queensland, which intensified into a cyclone named Kimi on the next day. Four additional tropical lows formed after Kimi, of which one managed to intensify into Tropical Cyclone Lucas before crossing into the South Pacific basin on February 3, while the other three had minor effects on land.
In the month of February, four tropical disturbances formed out of which two were named, being given the names Marian and Niran respectively. Marian formed on February 23 and rapidly intensified into a Category 3 severe tropical cyclone on the Australian scale. It briefly entered the MFR's area of responsibility between March 1 and March 2 before re-entering into the basin on March 3, where it peaked as a Category 4 severe tropical cyclone on the Australian Scale. Niran formed on February 27 and also rapidly intensified, peaking as a Category 5 severe tropical cyclone. Although it remained offshore, its slow-motion caused damage to banana crops in Queensland. Niran exited the basin on March 5. In March, three tropical lows developed, though they did not intensify into tropical cyclones.
In the month of April, four systems have formed, with two being named Seroja by TCWC Jakarta and Odette by BoM. The two systems engaged in a Fujiwhara interaction, with Seroja eventually absorbing Odette. The former would go on to intensify and strike Australia as a Category 3 severe tropical cyclone. On April 9, a tropical low formed off the east coast of Australia and quickly exited on the same day. On April 23, a late-season tropical low formed to the east of the Arafura Sea. On May 31 a very rare tropical low formed near the Cocos Islands and dissipated without any significant intensification on 4 June.
July - December[]
South Pacific Ocean[]
January - June[]
In January 2021, four tropical disturbances formed in the South Pacific, all four of which intensified into tropical depressions, with Ana and Bina intensifying into tropical cyclones. On February 1, Lucas entered from the Australian region and affected New Caledonia and Vanuatu. A tropical depression designated as 09F formed on February 7, before it was upgraded into a tropical storm by the JTWC. However, it accelerated southwards and became extratropical on February 11. Another tropical depression designated as 10F formed on February 22, before dissipating on February 24. Niran entered the basin on March 5 and caused extensive damage in New Caledonia before accelerating southeast as it transitioned into an extratropical cyclone. On March 5, a short-lived tropical depression designated as 11F existed from March 5 to March 6. On April 9, a tropical depression designated as 13F entered the basin, however, it dissipated on April 11 without intensifying into a tropical cyclone.
July - December[]
South Atlantic Ocean[]
On February 6, a weak system unofficially designated as 01Q was briefly tracked by the NOAA. The system formed and dissipated on the same day without being monitored by the Brazilian Navy. Another system formed on February 14 near Rio Grande do Sul, being designated as a subtropical depression by the Brazilian Navy. On April 19, a subtropical depression formed, although its precursor formed off the coast of Rio de Janeiro. On April 20 the subtropical depression gained strength and was classified as a subtropical storm by the Brazilian Navy, being assigned the name Potira. It brought gale-force winds to Copacabana. On June 28, an extratropical cyclone in Uruguay transitioned into a subtropical depression on the evening of the same day, being given the designation Invest 1N by the NOAA. A day later, the storm strengthened into a subtropical storm. On June 29, as the subtropical storm entered Brazilian maritime territory, the Brazilian Navy named it Raoni.[7]
Systems[]
January[]
January was unusually above-average, with fourteen tropical cyclones forming and seven being named. Before that, two systems crossed into the 2021 season after having formed during the previous year. Danilo was one of the systems that crossed over, peaking as a severe tropical storm and briefly passing near the Mascarene Islands. A tropical depression designated as 05 entered the South-West Indian Ocean basin on December 28 and caused a brief interaction with Danilo before dissipating on January 3. In the Australian region, Cyclone Imogen formed on January 1 and affected Far North Queensland, bringing minimal damage to the area. Following Imogen, Cyclone Joshua, Cyclone Kimi, and Cyclone Lucas developed, with Joshua later entering the South-West Indian Ocean on January 17. Kimi threatened to strike the coast of Queensland, but weakened suddenly due to unexpected wind shear, remaining just offshore instead. Lucas formed on January 25 and entered the South Pacific basin on February 1. Additionally, four tropical lows formed in the basin, out of which one system entered the South-West Indian Ocean basin. In the South-West Indian Ocean, Cyclone Eloise formed and first made landfall on Madagascar as a severe tropical storm. It rapidly intensified over the Mozambique Channel and became the strongest storm of the month shortly before making a damaging landfall on Mozambique, with its remnants entering Zimbabwe, Eswatini, and South Africa. In the South Pacific, two tropical depressions formed, which were later assigned the names Ana and Bina, both of them affected Fiji and Vanuatu. In the West Pacific, a tropical depression formed, which became the first Northern Hemisphere tropical cyclone of 2021 and also marked the beginning of the 2021 Pacific typhoon season.

February[]
February was slightly above-average, featuring eleven systems, of which five were named. One system was unofficial and another was subtropical. In the Australian region, two tropical lows formed on February 6 and 18 respectively. Cyclone Marian formed on February 23 and rapidly intensified, reaching Category 3-equivalent strength on February 28 with Niran following on February 27 and reaching Category 5 strength on both the Australian scale and the Saffir–Simpson scale, bringing impacts to Queensland and New Caledonia. In the South Pacific, a tropical depression formed north of Fiji and strengthened, though it accelerated southwards and became extratropical on February 11. Another tropical disturbance also briefly existed from February 22 to 24. In the South-West Indian Ocean, Cyclone Faraji formed and rapidly intensified, being classified as a very intense tropical cyclone before becoming the strongest storm of the month as it strengthened into the first Category 5-equivalent tropical cyclone in the basin since Cyclone Fantala in 2016. It also became the first very intense tropical cyclone recorded in the month of February. It then began to gradually weaken, dissipating on February 13. Another system formed on February 10 and made landfall on Mozambique before re-emerging back over water, and was given the name Guambe before reaching tropical cyclone status. In the Western Pacific, Tropical Storm Dujuan formed and became the basin's first named storm, bringing minor damage to the Philippines. In the South Atlantic, one system was unofficially monitored by NOAA, being given the unofficial designation of 01Q. However, the Brazilian Navy did not monitor the system. Another system formed near Rio Grande do Sul and was designated as a subtropical depression by the Brazilian Navy.

March[]
March was slightly below-average, featuring nine tropical cyclones with only two being named. In the Australian region, five tropical lows formed on March 10, 18, 21, and 29 respectively. In the South Pacific, a tropical depression formed and was designated as 11F, though it was short-lived, dissipating the next day. In the South-West Indian Ocean, Cyclone Habana formed and explosively intensified to an intense tropical cyclone, persisting for two weeks and reaching three individual peak intensities. Forming along with Habana was Tropical Storm Iman, which made landfall on Madagascar as a tropical depression and bringing heavy rainfall to Réunion, dissipating a few days later. In the West Pacific, a tropical depression formed on March 14, however it was short-lived, dissipating the same day.

April[]
April was above-average, featuring nine systems, of which five were named. In the Australian region, Cyclone Seroja formed near East Timor and Indonesia. Its precursor caused catastrophic damage and deadly landslides in the West Nusa Tenggara and East Nusa Tenggara provinces of Indonesia and East Timor, causing 229 fatalities before strengthening to a Category 3 severe tropical cyclone and making a rare landfall on Midwestern Australia, becoming the first since Elaine in 1999. Cyclone Odette also formed in the region near the Cocos Islands before undergoing a Fujiwhara interaction with Seroja quickly after its formation and later being absorbed by it. Additionally, two tropical lows formed on April 7 and April 9, of which one entered the South Pacific basin. In the North Indian Ocean, a short-lived tropical depression formed off the Myanmar coast in the north Andaman Sea, however it dissipated the next day. In the Australian region, a tropical low formed before later moving into the South Pacific basin, being designated as 13F; it was short-lived and dissipated on April 11. In the South-West Indian Ocean, Cyclone Jobo developed near the Seychelles, undergoing a brief period of rapid intensification before dissipating near Tanzania on April 24. In the West Pacific, Typhoon Surigae formed south of Woleai and rapidly intensified into a Category 5-equivalent typhoon, becoming the strongest typhoon recorded in the month of April as it passed near the Philippines. In the South Atlantic, Subtropical Storm Potira formed just off the coast of Rio de Janeiro, causing gale-force winds in Copacabana.

May[]
May was well above average, even though tropical cyclogenesis started in mid-May. It featured the formation of nine systems, with six being named. In the Australian region near the Cocos Islands, an off-season tropical low formed before dissipating on June 3. In the East Pacific, Tropical Storm Andres formed and peaked as a tropical storm, becoming the earliest named storm in the basin in the East Pacific east of 140°W, breaking the previous record of Adrian in 2017 by twelve hours. Tropical Storm Blanca also formed and peaked as a tropical storm near the end of the month. In the North Atlantic, Tropical Storm Ana formed northeast of Bermuda as a subtropical storm before later transitioning into a tropical storm, marking the seventh consecutive Atlantic hurricane season to feature a storm formed before the official start date. In the North Indian Ocean, Cyclone Tauktae formed off the coast of Kerala and Lakshadweep and rapidly intensified to Category 4 equivalent storm, becoming the strongest storm of the month. It made a devastating landfall in Gujarat. Ten days later, Cyclone Yaas formed in the Bay of Bengal and intensified into a Category 1 equivalent strength, eventually making landfall in northwestern Odisha on May 26. Both storms brought considerable damage and loss of lives. In the West Pacific, a tropical depression formed on May 12 before making landfall on the Philippines and dissipating shortly thereafter. Tropical Storm Choi-wan and a tropical depression also formed later in the month, with Choi-wan peaking as a tropical storm. Choi-wan made several landfalls in the Philippines, causing severe damage. It later weakened into a tropical depression before transitioning into an extratropical cyclone.

August[]
August was average, featuring eighteen tropical cyclones, with sixteen of them being named. In the East Pacific, Tropical Storm Ignacio formed, but dissipated a few days later due to strong wind shear partially due to its proximity to Hurricane Hilda. Tropical Storm Kevin would then form a couple of days later, off the coast of Mexico with Hurricane Linda following shortly after, peaking as a low-end Category 4-equivalent hurricane. Linda was to be followed by Tropical Storm Marty and Hurricane Nora. In the West Pacific, tropical storms Lupit, Mirinae, Nida and Omais formed, with Lupit making landfall in China and Japan. In the North Atlantic, Tropical Storm Fred formed south of Puerto Rico and made landfall in the Florida Panhandle, with Hurricanes Grace and Henri forming later. Grace impacted the Caribbean before making landfall on the Yucatán Peninsula before rapidly intensifying in the Bay of Campeche and making landfall as a category 3 hurricane in mainland Mexico. Henri would impact the Northeastern United States as a tropical storm, becoming the first tropical cyclone to make landfall in Rhode Island since Hurricane Bob in 1991. At the end of the month, Hurricanes Ida and Larry, as well as tropical storms Julian and Kate, and formed. Ida, which became the strongest storm of the month, brought impacts to Cuba before striking Louisiana on August 29, notably on the 16th anniversary of Hurricane Katrina, tying with Hurricane Laura of the previous season and the 1856 Last Island Hurricane as the strongest hurricane to make landfall in the state by maximum winds.
