1935 Atlantic hurricane season

The 1935 Atlantic hurricane season was a near-normal hurricane season. Altogether, ten tropical cyclones developed, eight of which intensified into tropical storms. Five of those tropical storms strengthened into hurricanes, while three of those reached major hurricane intensity. The season ran from June 1 through November 15, 1935.

There were five notable systems in 1935. A weakening late-August hurricane sank numerous ships off the coast of Newfoundland, causing 50 fatalities. In early September, the Labor Day hurricane made landfall in Florida twice, the first time as a Category 5 hurricane on the modern day Saffir–Simpson scale, the first Category 5 U.S. landfall on record, resulting in about 490 deaths and $100 million (1935 USD) in damage along its path. It was the most intense Atlantic hurricane on record in terms of barometric pressure, a record later surpassed by Hurricane Gilbert in 1988, as well as the strongest at landfall by 1-minute sustained winds, a record equalled by Hurricane Dorian in 2019. It is also one of only four Category 5 hurricanes on record to strike the contiguous United States, along with Hurricane Camille (1969), Hurricane Andrew (1992), and Hurricane Michael (2018).

Late in September, the Cuba hurricane struck the country as a Category 3 and later the Bahamas as a Category 4. The hurricane caused 52 fatalities and roughly $14.5 million in damage. The Jérémie hurricane caused significant impacts in Cuba, Haiti, Honduras, and Jamaica in the month of October. Overall, the storm was attributed to about 2,150 deaths and $16 million in damage, with more than 2,000 fatalities in Haiti alone. The Yankee hurricane struck the Bahamas and Florida in early November. The system resulted in 19 deaths, while damage totaled roughly $5.5 million. Collectively, the tropical cyclones of the 1935 Atlantic hurricane season caused roughly $136 million in damage and 2,761 fatalities.

The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 106 units, slightly higher than the 1931–1943 average of 91.2. 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.
