The 1963 Atlantic hurricane season was a below average North Atlantic hurricane season, with nine total storms completing tropical cyclogenesis. Despite the below-average number of storms, the number of hurricanes and major hurricanes (Category 3 or higher on the SSHS) were near average.

The first storm, Tropical Storm Arlene, formed on August 1, and the last storm, Tropical Storm Irene, dissipated on October 6. The strongest storms, Hurricanes Cindy and Ginny, both reached a minimum barometric pressure of 963 millibars (mbar). Mainly due to Hurricanes Beulah and Flora, the season caused 245 fatalities and $200 million (1963 USD) dollars in damage.


Season summary

As a whole, the 1963 season was below average. This was due to a moderate El Niño persisting throughout the season's entire duration. An abnormal feature of this season was a streak of seven tropical storms (Beulah, Cindy, Debra, Edith, Flora, Ginny, and Helena) making landfall within American soil, an all time record.

August saw four total tropical cyclones: Tropical Storm Arlene, Tropical Depression Two, Hurricane Beulah, and Hurricane Cindy. Arlene and Tropical Depression Two stayed out in the open Atlantic Ocean, while Beulah and Cindy respectively made landfall near Louisiana and Savannah, Georgia as Category 1 hurricanes, causing 100 deaths and $75 million (1963 USD) and 47 deaths and $20 million (1963 USD), respectively. Despite the active August, an even more active September was on the way.

September saw seven tropical cyclones: Tropical Storm Debra, Hurricane Edith, Hurricane Flora, Tropical Depression Eight, Tropical Depression Nine, Hurricane Ginny, and Hurricane Helena. Debra caused 13 deaths and $5 million (1963 USD) following its Sabine Pass, Texas landfall. Edith was the only hurricane on record (doing so at Category 1 intensity over Jacksonville, Florida) to make landfall on the First Coast region of Florida until Hurricane Dora the next year. Fortunately, due to advanced preparations, Edith only caused 4 deaths and $3 million (1963 USD) in damages. Tropical Depressions Eight and Nine stayed out to sea, causing no known damage or deaths. Flora was the deadliest and costliest storm of the year. Following its Category 2 landfall near Mobile, Alabama, it caused 120 deaths and $130 million (1963 USD) in damages. Ginny, on the heels of Hurricane Flora, was steered into Florida near Punta Gorda as a Category 1 hurricane, causing a death and $5 million (1963 USD) dollars in damage. The final storm, Hurricane Helena, made a landfall near Daytona Beach, Florida as a tropical storm, but fortunately did not kill anyone and had an extremely low damage total of $2 million. Following an active September, activity in October rapidly slowed down.

October saw only one tropical cyclone, Tropical Storm Irene, capping off the season. It did not affect land.

The season's activity was reflected with an extremely low accumulated cyclone energy (ACE) rating of 29, which is categorized as below normal. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength. Subtropical cyclones are excluded from the total. The reason the ACE was so low this year was because almost all of the storms were short-lived and did not have much time to intensify.
