High Quality Content by WIKIPEDIA articles! The 1961 Atlantic hurricane season officially began on June 15, 1961, and lasted until November 15, 1961. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The season had seven major hurricanes, the second highest number on record, despite having only eight total hurricanes. It is also one of only four seasons to have two or more hurricanes reach Category 5 status on the Saffir-Simpson Hurricane Scale, the others being the 1960, 2005, and the 2007 season.
