Timeline of the 2018 Pacific hurricane season
The 2018 Pacific hurricane season was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the eastern Pacific Ocean. The season officially started on May 15 in the eastern Pacific—east of 140°W—and began on June 1 in the central Pacific—between the International Date Line and 140°W, and ended on November 30. These dates typically cover the period of each year when most tropical cyclones form in the eastern Pacific basin.[1] The season's first storm, Tropical Depression One-E, developed on May 10; the season's final storm, Tropical Storm Xavier, dissipated as a tropical cyclone on November 5.

The 2018 hurricane season was exceptionally active and featured the highest Accumulated Cyclone Energy since reliable records began in 1971.[2] Throughout the season, 26 tropical depressions developed, 23 of which became tropical storms, 13 of them reached hurricane strength, and 10 achieved major hurricane intensity.[3][nb 1] The basin saw above-average activity across all regions from the International Dateline to the west coast of Mexico and Central America. Activity peaked during a 10-week period from early August to early October, with several long-lived and powerful hurricanes developing. Several storms had significant land impacts, including Hurricane Lane in Hawaii and Hurricane Willa in Mexico. In contrast to the similarly active 2015 Pacific hurricane season, 2018 was not significantly influenced by the El Niño–Southern Oscillation. Instead, low pressures and increased sea surface temperatures associated with the Pacific Meridional Mode supported the development intense and long-lived storms.[2]
Four time zones are utilized in the basin: Central for storms east of 106°W, Mountain between 114.9°W and 106°W, Pacific between 140°W and 115°W,[5] and Hawaii–Aleutian for storms between the International Date Line and 140°W. However, for convenience, all information is listed by Coordinated Universal Time (UTC) first with the respective local time included in parentheses. This timeline includes information that was not operationally released, meaning that data from post-storm reviews by the National Hurricane Center is included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.

Notes
- A major hurricane is a storm that ranks as Category 3 or higher on the Saffir–Simpson hurricane wind scale.[4]
- Formation indicates the date when a system became a tropical or subtropical cyclone.
- Dissipation indicates the date when a system ceased being a tropical or subtropical cyclone by way of dissipation, degeneration into a remnant low, or transition into an extratropical cyclone.
- Hurricane Hector moved west of the International Dateline on August 13 and exited the Central Pacific Hurricane Center's area of responsibility. The system ultimately dissipated on August 16.[15]
- Although not officially warned upon, Invest 96C was analyzed as a subtropical cyclone by the Central Pacific Hurricane Center and a tropical cyclone by the National Oceanic and Atmospheric Administration's Satellite Products and Service Division.
- The figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (miles per hour, kilometers per hour, miles, or kilometers), following the convention used in the National Hurricane Center's operational products for each storm. All other units are rounded to the nearest digit.
- The record for earliest tropical cyclone formation in the Eastern Pacific proper as of 2021 is 2020's Tropical Depression One-E on April 25.[36]
- Operationally, the depression that became Hurricane Walaka was not warned upon until 21:00 UTC (11 a.m. HST) by which time it was already a tropical storm.[40] It would have received the designation "One-C" prior to being named.[30]
