1930 Atlantic hurricane season

The 1930 Atlantic hurricane season was the second least active Atlantic hurricane season on record in terms of tropical storms formed, only behind 1914, with only three systems reaching tropical storm intensity. Of those three, two reached hurricane status, both of which also became major hurricanes, Category 3 or higher storms on the Saffir–Simpson hurricane wind scale. The first system developed in the central Atlantic Ocean on August 21. Later that month, a second storm, the Dominican Republic hurricane, formed on August 29. It peaked as a Category 4 hurricane with winds of 155 mph (250 km/h). The third and final storm dissipated on October 21.

Due to the lack of systems that developed, only one tropical cyclone, the second hurricane, managed to make landfall during the season. It severely impacted areas of the Greater Antilles, particularly the Dominican Republic, where an estimated 2,000 to 8,000 people died, before making subsequent landfalls on Cuba and the U.S. states of Florida and North Carolina, with less severe effects.

The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 50, below the 1921–1930 average of 76.6. ACE is a metric used to express the energy used by a tropical cyclone during its lifetime. Therefore, a storm with a longer duration will have high values of ACE. It is only calculated at six-hour increments in which specific tropical and subtropical systems are either at or above sustained wind speeds of 39 mph (63 km/h), which is the threshold for tropical storm intensity. Thus, tropical depressions are not included here.
