The 1991 Atlantic hurricane season was a below-average Atlantic hurricane season that produced twelve tropical cyclones, of which eight strengthened to become named tropical storms; four of these became hurricanes, of which two further intensified into major hurricanes. The season officially began on June 1, 1991, and ended on November 30. These dates, adopted by convention, historically describe the period in each year when most subtropical or tropical cyclogenesis occurs in the Atlantic Ocean. The first system, Tropical Storm Ana, developed on July 2 while the last system, the unnamed Perfect Storm, dissipated on November 2.

The 1992 Atlantic hurricane season was among the least active of any Atlantic hurricane season on record. It produced six named tropical cyclones. The season officially started on June 1, 1992, and ended on November 30. 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 Subtropical Storm One formed on April 21. This timeline documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipations during the season.
