An off-season Atlantic hurricane is a recorded tropical or subtropical cyclone that existed in the Atlantic basin outside of the official Atlantic hurricane season. The National Oceanic and Atmospheric Administration currently defines the season as occurring between June 1 and November 30 each calendar year, which is when 97% of all Atlantic tropical cyclones occur. Peak activity is known to be between August and October. In the off-season, storms are most likely to occur in May, with approximately 60% of such storms occurring during that month. Occasionally, however, storms develop in or persist until December. As of 2016, there have been 77 off-season cyclones in the Atlantic hurricane database, which began in 1851. In addition, there were six storms before 1851, and one hurricane in 1863 that is not part of the official database. Off-season cyclones are most likely to occur in the central to western Atlantic Ocean, and most do not make landfall. Of the storms that did strike land, most affected areas surrounding the Caribbean Sea. (Full list...)
