2025 Atlantic hurricane season (Cooper)

The 2025 Atlantic hurricane season was the second most active Atlantic hurricane season on record, with 21 named storms forming. It officially began on June 1, 2025, and ended on November 30, 2025. These dates historically describe the period of year when most tropical cyclones form in the Atlantic basin. However, as shown by Tropical Storm Andrea in early May, tropical cyclone formation is possible at other times of the year.
