The 2021 Atlantic hurricane season was a below average season, featuring 10 named storms, 5 hurricanes, and 2 major hurricanes, which caused a total of over $102.845 billion (2021 USD) in damages. The season officially began on June 1, 2021, and ended on November 30, 2021. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, tropical cyclogenesis is possible at any time of the year.
The following list of names was used for named storms that formed in the North Atlantic in 2021. The names not retired from this list were used again in the 2027 season. This was the same list used in the 2015 season, with the exceptions of Elsa and Julian, which replaced Erika and Joaquin, respectively. The names Elsa and Julian were used for the first (and only, in the case of Elsa) time this year.
On April 8, 2021, at the 44th session of the RA IV hurricane committee, the World Meteorological Organization retired the names Elsa and Henri from their rotating naming lists due to the number of deaths and amount of damage they caused, and they will not be used again for another Atlantic hurricane. They will be replaced with Eva and Hudson for the 2027 season, respectively.
