Timeline of the 2020 Atlantic hurricane season

The 2020 Atlantic hurricane season was the most active Atlantic hurricane season on record in terms of number of named storms. Additionally, it was an above-average season for tropical cyclones for the fifth consecutive year. The season officially began on June 1, 2020, and ended on November 30, 2020. These dates, adopted by convention, historically delimit the period each year when most Atlantic tropical systems form. However, storm formation is possible at any time of the year, as was the case this season, when its first two named storms, Tropical Storm Arthur and Tropical Storm Bertha, formed on May 16 and May 27, respectively. The final storm, Hurricane Iota, dissipated on November 18.

Altogether, the season produced 31 tropical or subtropical cyclones, all but one of which became a named storm. Of the 30 named storms, 14 became hurricanes, and 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.

This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. It includes information that was not released throughout the season, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not initially warned upon, has been included.

The time stamp for each event is first stated using Coordinated Universal Time (UTC), the 24-hour clock where 00:00 = midnight UTC. The NHC uses both UTC and the time zone where the center of the tropical cyclone is currently located. The time zones utilized (east to west) are: Greenwich, Cape Verde, Atlantic, Eastern, and Central. In this timeline, the respective area time is included in parentheses. Additionally, figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (miles, or kilometers), following National Hurricane Center practice. Direct wind observations are rounded to the nearest whole number. Atmospheric pressures are listed to the nearest millibar and nearest hundredth of an inch of mercury.
