The 1916 Atlantic hurricane season featured eighteen tropical cyclones, of which nine made landfall in the United States, the most in one season until 2020, when eleven struck. The first storm appeared on May 13 south of Cuba, while the final tropical storm became an extratropical cyclone over the southeastern Gulf of Mexico on November 15. Of the 18 tropical cyclones forming that season, 15 intensified into a tropical storm, the second-most at the time, behind only 1887. Ten of the tropical storms intensified into a hurricane, while five of those became a major hurricane. The early 20th century lacked modern forecasting tools such as satellite imagery and documentation, and thus, the hurricane database from these years may be incomplete.

The 2020 Atlantic hurricane season was the most active Atlantic hurricane season on record, in terms of number of systems. It featured a total of 31 tropical or subtropical cyclones, with all but one cyclone becoming a named storm. Of the 30 named storms, 14 developed into hurricanes, and a record-tying seven further intensified into major hurricanes. It was the second and final season to use the Greek letter storm naming system, the first being 2005, the previous record. Of the 30 named storms, 11 of them made landfall in the contiguous United States, breaking the record of nine set in 1916. During the season, 27 tropical storms established a new record for earliest formation date by storm number. This season also featured a record ten tropical cyclones that underwent rapid intensification, tying it with 1995, as well as tying the record for most Category 4 hurricanes in a singular season in the Atlantic Basin. This unprecedented activity was fueled by a La Niña that developed in the summer months of 2020, continuing a stretch of above-average seasonal activity that began in 2016. Despite the record-high activity, this was the first season since 2015 in which no Category 5 hurricanes formed.
