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, as evidenced by the formation of Tropical Storm Bolaven in late December 2017, and Tropical Storm Pabuk on December 31, 2018. 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.
