The 1958 Pacific typhoon season was an event in the annual cycle of tropical cyclone formation. The season had no official bounds, but tropical cyclones in the Western Pacific Ocean normally develop between May and October. The season was below average in storms, with only twenty-three forming. However, all but two of those storms developed into typhoons, resulting in a well above-average number of typhoons, and a very high ACE figure of 445.8 units. In addition, there were also nine tropical storms tracked only by the JMA. The season began very early, with a very rare super typhoon in January, Typhoon Ophelia, and ended in early December with Typhoon Olga. It also featured Typhoon Ida, the strongest storm ever recorded at that time.
The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line. Storms that form east of the date line and north of the equator are called hurricanes; see 1958 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Fleet Weather Center on Guam.
