The 2024 Atlantic hurricane season was an extremely active and destructive Atlantic hurricane season that became the third-costliest on record, behind only 2017 and 2005. The season featured 18 named storms, 11 hurricanes, and 5 major hurricanes; it was also the first since 2019 to feature multiple Category 5 hurricanes. Additionally, the season had the highest accumulated cyclone energy (ACE) rating since 2020, with a total value of 161.5 units. The season officially began on June 1 and ended on November 30. These dates, adopted by convention, have historically described the period in each year when most subtropical or tropical cyclogenesis occurs in the Atlantic Ocean.
