Summary

[edit]
Description
English: An image showing a total of 94 tropical cyclones formed around the globe during the year 2021, which ties 1994 for the tenth most since 1981. Despite this above-normal number of named storms, the overall global tropical cyclone activity was down in 2021. Only 37 tropical cyclones made hurricane strength (>74 mph), which is the fewest on record since 1981. The previous record was 38 in 2009. In addition, 16 storms reached major hurricane strength (>111 mph), which tied 1986 for the third-fewest. Six storms reached category 5 strength (>157 mph) on the Saffir-Simpson Hurricane Wind Scale (SSHWS), which is slightly above the normal. The global accumulated cyclone energy (ACE: an integrated metric of the strength, frequency, and duration of tropical storms) was about 22% below the 1991-2020 average.
