It made landfall in Louisiana with maximum sustained winds of 150 mph (240 km/h), destroying coastal communities in its path; parts of the New Orleans metropolitan area were left without power for several weeks. The storm caused an estimated $75 billion in damages in the U.S. and it was responsible for 87 deaths. Over half of those deaths occurred in New York and New Jersey, as the hurricane's remnants brought rains that triggered widespread flooding throughout that region. Additionally, heavy rains caused widespread flooding and landslides across Venezuela as Ida's precursor tropical wave passed though the southeastern Caribbean Sea, resulting in at least 20 deaths. In April 2022, the name Ida was retired from reuse in the North Atlantic by the World Meteorological Organization due to the extraordinary amount of damage and number of fatalities it caused.

The season's first storm, Tropical Storm Alex, formed on June 5, and the last, Hurricane Nicole, dissipated on November 11.
