The 2025 Atlantic hurricane season was a near-average season in the Atlantic Ocean in the Northern Hemisphere. The season officially began on June 1, and ended on November 30. These dates, adopted by convention, historically describe the period in each year when most subtropical or tropical cyclogenesis occurs in the Atlantic Ocean (over 97%).[1] No subtropical or tropical development occurred in the Atlantic prior to the start of the season, as the first system, Tropical Storm Andrea, did not form until June 23. Overall, 13 named storms formed; 5 of those became hurricanes, of which 4 strengthened into major hurricanes.[nb 1] The season featured three Category 5 hurricanes, the highest rank on the Saffir-Simpson scale. Among the three was Hurricane Melissa, the final storm of the season, which dissipated on October 31.

This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. It includes information that was not released throughout the season, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not initially warned upon, has been included.

The time stamp for each event is first stated using Coordinated Universal Time (UTC), the 24-hour clock where 00:00 is midnight UTC.[3] The NHC uses both UTC and the time zone where the center of the tropical cyclone is currently located. The time zones utilized (east to west) are: Greenwich, Cape Verde, Atlantic, Eastern, and Central.[4] In this timeline, the respective area time is included in parentheses. Additionally, figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (miles, or kilometers), following National Hurricane Center practice. Direct wind observations are rounded to the nearest whole number. Atmospheric pressures are listed to the nearest millibar and nearest hundredth of an inch of mercury.

Notes

  1. ^ Hurricanes reaching Category 3 and higher—1-minute sustained winds higher than 110 miles per hour (178 km/h)—on the Saffir–Simpson scale are described as major hurricanes.[2]
  2. ^ Due to the threat the developing system posed to the Bahamas, the National Hurricane Center initiated advisories on it, designating it Potential Tropical Cyclone Nine at 21:00 UTC (5:00 p.m. EDT) on September 26.[15]
