2020 Atlantic hurricane season (Blackford)

The 2020 Atlantic hurricane season was the first below-average season since 2015, and ended the series of above to well above-average seasons from 2016 to 2019. Despite this, it was the record sixth-consecutive season in a row where a tropical or subtropical storm formed before the official start of the season.

After this season, starting in 2021, the Atlantic hurricane season would begin on May 15. This season also contained one of the least-active Septembers ever recorded.
