Timeline of the 1980 Atlantic hurricane season

The 1980 Atlantic hurricane season was an average Atlantic hurricane season in which eleven named storms formed. Although Tropical Depression One formed on July 17, the season officially began on June 1 and ended on November 30, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The season's final storm, Hurricane Karl, dissipated on November 27.

The season produced fourteen tropical depressions, of which twelve intensified into tropical storms, four became hurricanes, and two became major hurricanes. The only significant storm during the season was Hurricane Allen, a long-lived Cape Verde-type hurricane that became one of the strongest hurricanes recorded in the Atlantic Ocean, as well as the earliest Category 5 hurricane on the Saffir–Simpson Hurricane Wind Scale ever recorded, a record that stood until Hurricane Emily during the 2005 season. Allen reached its peak intensity with maximum sustained winds of 190 mph (310 km/h) with a minimum barometric pressure of 899 mbar (hPa; 26.55 inHg).
