The 1933 Atlantic hurricane season set the pre-weather satellite record for most tropical storms formed within a single season, and currently ranks as the third-most active Atlantic hurricane season, only behind 2005 and 2020. It also produced the highest Accumulated Cyclone Energy (ACE) on record in the Atlantic basin, with a total of 259. The season ran through the summer and the first half of fall in 1933, with activity as early as May and as late as November. A tropical cyclone was active for all but 13 days from June 28 to October 7.
