The 2018 Pacific typhoon season was formerly the costliest Pacific typhoon season on record before being surpassed the following year. The season had no official boundaries, and storms can form year-round. Despite this, activity usually peaks between May and November. The season featured above-average activity, with 29 named storms, 13 typhoons, and 7 super typhoons forming in the West Pacific.[2][4][nb 2] The season's first named storm, Bolaven, developed on January 3, while the season's last named storm, Man-yi, dissipated on November 28. The season's first typhoon, Jelawat, reached typhoon status on March 29, eventually becoming also the first super typhoon the next day.
This timeline documents all of the events of the 2018 Pacific typhoon season. Most of the tropical cyclones form between May and November. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. The Japan Meteorological Agency (JMA) is the official Regional Specialized Meteorological Centre for the Western Pacific Basin. As such, it is responsible for assigning names to all tropical cyclones that reach 10-minute maximum sustained winds of at least 65 kilometres per hour (40 mph) in the region.[6] The Joint Typhoon Warning Center (JTWC) also monitors systems in the Western Pacific Basin, assigning systems a number with a "W" suffix if the system is a tropical depression or stronger. PAGASA also assigns local names to tropical depressions or stronger which form within or enter their area of responsibility, regardless if the JMA has assigned the cyclone a name; however, these names are not in common use outside of PAGASA's area of responsibility.[7] In this season, 21 systems entered or formed in the Philippine Area of Responsibility (PAR), of which 7 of them made landfall over the Philippines.

Notes
- While Pabuk formed during the 2018 season as being the last system, it was considered to be part of the 2019 Pacific typhoon season, based on the JMA's annual report, thus, 35W (Usman) would be the last system of this season while Pabuk would be the first system for the following season.[1][2][3]
- Super typhoons are an unofficial classification given by the Joint Typhoon Warning Center for storms whose strength are 130 knots (240 km/h; 150 mph) or above.[5]
